摘要： PROBLEM TO BE SOLVED: To surely prevent sliding on a bad road causing reverse input application from a road surface side, to reduce belt clamping force (frictional force) on a flat road causing hardly reverse input application as much as possible and to further reduce power loss by friction. SOLUTION: Car navigation information including traveling path information is taken from a navigation system (S1). Based on the traveling path information, whether the present traveling path and a near future traveling path are flat roads or bad roads is decided (S2). Surely avoiding sliding of a transmission belt caused by irregular parts of a road surface on the bad road by selecting a map for bad road having higher belt clamping force of a belt type continuously variable transmission as compared with the flat road in the case of the bad road (S6), belt clamping force is remarkably lowered on the flat road and power loss is reduced.

摘要： PURPOSE:To improve the extent of finishing accuracy in the cam end face of a camshaft. CONSTITUTION:Each of pistons 17, 18 is fitted in two cylinder parts 12 and 16 connected to a spindle 5. Each of disks 3, 4 equipped with lapping wheels 3a, 4a is attached to these pistons 17 and 18. A hydraulic circuit 24 is connected to the cylinder parts 12, 16 and a controller 29 is connected to an electrohydrostatic control valve 25. A work W (camshaft) is set to a turning shaft 2, rotating this shaft 2 and the spindle 5, and both end face of a cam C are machined by the lapping wheels 3a and 4a. On the basis of a turning angle of the work W detected by a phase detector 30, the electrohydrostatic control valve 25 is controlled by the controller 29 according to a contact area between the lapping wheels 3a, 4a and a machining surface of the cam C. In succession, hydraulic pressure being supplied to the cylinder parts 12, 16 from the hydraulic circuit 24 is regulated and thereby contact pressure between the lapping wheels 3a, 4a and the machining surface of the cam C is kept constant. In consequence, the extent of machining progress becomes constant and finishing accuracy on the machined surface is thus improved.

摘要： PURPOSE:To reduce torque fluctuation of a cam shaft in the variable valve device in an internal combustion engine so as to easily disassemble and assemble two parts discriminated from view of their functions. CONSTITUTION:A variable valve timing device(VVT) 1 comprises a phase conversion part 9 for converting rotational phase of a cam shaft 5 and a hydraulic driving part 10 for driving the phase conversion part 9. The phase conversion part 9 is provided rotatably in one body together with the cam shaft 5, and the casing 22 of the driving part 10 is provided on-rotatably on a cylinder head 3. The ring gear 13 of the phase conversion part 9 is connected to the operating rod 24 of the driving part 10 in such a way that a bearing 26 is fit in the sleeve 20 of the ring gear 13 to be prevented from slipping off by a cisclip 37. It is thus possible to reduce an inertia load applied on the cam shaft 5 at the time of rotation by only an amount due to the driving part 10. The cisclip 37 is operated from the outer circumferential side of the sleeve 20, and thereby, the sleeve 20 is disconnected and/or connected from/to the bearing 26.

摘要： PURPOSE:To improve fuel consumption by preventing a decrease in an engine output while reducing any pumping loss during low load running of an internal combustion engine. CONSTITUTION:An intake air control device comprises a variable valve timing device, a throttle valve 14, a bypass passage 16, an intake air regulating valve 17, an acceleration opening sensor 20, and a number of revolution sensor 21. A CPU decides an operation state by means of signals from both sensors 20 and 21 and controls the variable timing device and the intake air pressure regulating valve 17. The CPU closes the bypass passage 16 at other time than low load running to stop the feed of auxiliary air to a combustion chamber 4, and adjusts the closing timing of an intake air valve 7 to a predetermined timing. Further, during low load running, the bypass passage 16 is opened to feed auxiliary air to a combustion chamber 4 so that a pressure in an intake air pipe is reduced to a given pressure slightly lower than the atmospheric pressure. Simultaneously, the closing timing of the intake valve 7 is further delayed than a predetermined timing so as to regulate an intake air amount.

摘要： PURPOSE:To achieve miniaturization in the axial direction by varying a rotating phase without moving an operating member in the axial direction in a valve timing controller for an internal combustion engine. CONSTITUTION:A timing pulley 10 is disposed at one end of a camshaft 1. An external tooth rotor 16 and an internal tooth rotor 17 are provided in the camshaft 1 and the timing pulley 10, respectively, for integral rotation. The internal tooth rotor 17 is connected to the external tooth rotor 16, thus constituting a pair of trochoid gears 18 together with the external tooth rotor 16. The internal tooth rotor 17 is integrally incorporated In a containing recess portion 7 of a casing 8 mounted on the camshaft 1. A motor 36 is drivingly connected to an external tooth 34 of the casing 8. When torsion is applied to the camshaft 1 with respect to the timing pulley 10, the casing 8 is rotated by the motor 36. Consequently, a deviated position of the internal tooth rotor 17 with respect to the external tooth rotor 16 is shifted around the center of the external tooth rotor 16, thereby changing a rotating phase of the timing pulley 10 and the camshaft 1.

摘要： PURPOSE:To reduce engaging noise at the time of operation, and prevent large resistance from being generated when a ring gear is moved, in a variable valve timing device for moving the ring gear interposed between a timing pulley and a cam shaft in an axial line direction so as to change a phase between the timing pulley and the cam shaft. CONSTITUTION:Rotation is transfered from a timing pulley 3 to a cam shaft 1 through a ring gear 15 interposed between the cam shaft 1 and the timing pulley 3 and provided with helical splines 11a, 11b. The ring gear 15 is moved between a first and second operating positions which are separated from each other in an axial line direction so as to change a phase between the timing pulley 3 and the cam shaft 1. Stoppers 30, 32, 34, 36 are provided respectively on the first and second operating positions of of a sleeve 5 and a housing 11. When the ring gear 15 is positioned in the first and second operating positions, the ring gear 15 is pushed elastically along circumference direction through blocks 31, 33, 35, 37 so as to prevent relative rotation between the timing pulley 3 and the cam shaft 1.

摘要： PURPOSE:To provide a variable valve timing device by giving a backlash at the time a ring gear moves and reducing the backlash at the time the ring gear stops. CONSTITUTION:A ring gear 13 is interposed between a cam shaft 1 and a timing pulley assembly 6 to connect both components 1 and 6 and at the same time gives torsion to the cam shaft 1 by rotation and movement in the axial direction. The ring gear 13 is moved by control oil pressure applied to its one end through a shaft passage 23. The ring gear 13 consists of a pair of divided gears 14 and 15 capable of relatively moving in the axial direction by a predetermined distance. When the ring gear 13 stops, the lines of teeth of both divided gears 14 and 15 are not lined up to make backlash small. When the ring gear 13 is moved in the axial direction by the control oil pressure, control oil is supplied through an oil pressure supply passage 29 between both divided gears 14 and 15 to make a gap G between both divided gears 14 and 15. As a result, the lines of both of the divided gears 14 and 15 are lined up to increase the backlash.

摘要： PROBLEM TO BE SOLVED: To provide a fuel injection valve having improved mountability by reducing the axial length of the fuel injection valve.
SOLUTION: The fuel injection valve 11 comprises an actuator 28 consisting of a piezoelectric element, a displacement enlarging mechanism 30, and a needle valve 22. The displacement enlarging mechanism 30 has a first piston 31 and a second piston 32 arranged via a fixed-capacity displacement enlarging chamber 33 in which fuel is stored. The pressure receiving area of the second piston 32 is smaller than that of the first piston 31. The displacement enlarging mechanism 30 enlarges the displacement of the first piston 31 in the displacement enlarging chamber 33 with the expansion of the actuator 28 and transmits it to the second piston 32. In this fuel injection valve 11, both pistons 31, 32 are arranged so that the second piston 32 is displaced in the opposite direction to the first piston 31 and at least part of the movable range of the second piston 32 is overlapped with the movable range of the first piston 31. The displacement enlarging chamber 33 is provided at the ends (the lower ends) of both pistons 31, 32 on the same side.

摘要： PURPOSE:To simplify a power steering device compared with the case where a torsion bar is arranged in a through hole of an input shaft by elastically holding a rolling body between an input side member and an output side member which are respectively fixed to the input shaft and an output shaft, and thereby generating the return torque. CONSTITUTION:When a steering wheel 18 is operated in order to change the direction of steered wheels, an input shaft 12 is relatively rotated to an output shaft 22. If the relative rotational angle is set to theta, the elliptical external circumferential surface 74 of a cylindrical member 70 of uneven wall thickness is moved in the circumferential direction by the angle theta relative to a ball 104. That means, the ball 104 is rolled to permit the movement of the cylindrical member 70 of uneven wall thickness, and the elastic force of the cylindrical member 70 of uneven wall thickness is increased thereby, and the return torque is generated between the input shaft 12 and the output shaft 22. As a thick part of the cylindrical member 70 of uneven wall thickness is brought into contact with the ball 104, the elastic force is increased. In addition, when the operating force of the steering wheel 18 is released, the input shaft 12 is reversely rotated, and the input shaft 12 and the output shaft 22 are returned to the original relative phase.

摘要： PURPOSE:To miniaturize a valve timing control device in axial direction so as to rotate a timing pulley around the same center as that of a cam shaft by varying a rotating phase without moving an operating member in axial direction. CONSTITUTION:A timing pulley 10 and an external gear rotor 16 are provided on a cam shaft 1, and a trochoid gear pair 18 comprises an external gear rotor 16 and an internal gear rotor 17. The internal gear rotor 17 is assembled to the storing recessed part 7 of a casing 8. The internal gear rotor 17 is connected to the timing pulley 10 through a slider group 22. A motor 40 is drivingly- connected to the external gear 38 of the casing 8. The internal gear rotor 17 revolves around the external gear rotor 16 by rotating the casing 8 by means of the motor 40 so as to change a rotational phase between the cam shaft 1 and the timing pulley 10. At this time, motion in radial direction at the time of revolution of the internal gear rotor 17 is absorbed by the slider group 22, and only turning effort of the internal gear rotor 17 is transmitted to the timing pulley 10 by the slider group 22.
