摘要： A variable camshaft timing system (VCT system) for an internal combustion engine having a rotatable crankshaft (22) and a rotatable camshaft (26, 126). The camshaft (26, 126) is position variable relative to the crankshaft (22). A spool valve (192) including a spool (200) slidable within a cylindrical member (198) selectively controls the movement of hydraulic fluid for actuating the oscillation of the hydraulic operators (54, 56, 160a, 160b) within the housing recess (132a, 132b) as the housing oscillates with respect to the camshaft (26, 126). In accordance with various aspects of the present invention, the VCT system also includes a means for controlling the position of the spool (200), a means for removing air from the VCT system and seals (160h) for sealing the housing (130) outer periphery to prevent hydraulic fluid from draining out of the VCT system when the engine is shut down.

摘要： A camshaft (326) has a vane (360) secured to an end thereof for a non-oscating rotation therewith. The camshaft also carries a timing belt driven pulley (332) which can rotate with the camshaft but which is oscillatable with respect to the camshaft. The vane has opposed lobes (360a, 360b) which are received in opposed recesses (332a, 332b), respectively, of the pulley. The recesses have greater circumferential extent than the lobes to permit the vane and sprocket to oscillate with respect to one another and thereby permit the camshaft to change in phase relative to a crankshaft whose phase relative to the sprocket is fixed by virtue of the timing belt (338) drive extending therebetween. The camshaft tends to change in reaction to torque pulses which it experiences during its normal operation and it is permitted to advance or retard by selectively blocking or permitting the flow of engine oil from the recesses by controlling the position of a spool (400) within a valve body (392) of a control valve in response to a signal from an engine control unit (408). The spool is urged in a given direction by rotary linear motion translating means (682) which is rotated by an electric motor (686), preferably of the stepper motor type.

摘要： A phase shift device utilized for the camshaft sprockets in a chain control device for an engine having separate camshafts for intake and exhaust valves in an internal combustion engine. A device supporting one or a pair of idler sprockets is shiftable, either pivotally or longitudinally to vary the chain path between a driving and a driven camshaft sprocket in such a way as to vary the phase of the driven sprocket relative to the driving sprocket. This device comprises a bracket which carries at least one idler sprocket and is either pivotally or longitudinally shiftable to vary the phase thus facilitating proper chain control.

摘要： A driveshaft in the form of a crankshaft (12) or a camshaft (212) drives a camshaft (16, 216) by means of a chain (20, 220) which is trained around a sprocket (14, 214) on the driveshaft and another sprocket (18, 218) on the driven camshaft. The driven camshaft is selectively advanced or retarded in its position by lengthening or shortening one portion (20a, 220a) of the chain and simultaneously lengthening or shortening another portion (20b, 220b) thereof by extending one hydraulic tensioning device (22, 122, 222, 322) and simultaneously retracting another hydraulic tensioning device (24, 124, 224, 324). A spool valve member (50) is controllably positioned within a valve body (48), in response to instructions from an engine control unit (58) which acts through a pulse width modulated solenoid (56) to increase or decrease a load acting on one end of the spool, to permit or prevent hydraulic fluid from flowing from one tensioner to another as a result of a pressure differential between the tensioners. The pressure differential exists as a result of torque reversals in the driven camshaft during its normal rotation, the torque reversals having the effect of changing the levels of tension within the portions of the chain that are engaged by the tensioners.

摘要： A camshaft (426) has a vane (460) secured to an end thereof for non-osciling rotation therewith. The camshaft also carries a sprocket (432) which can rotate with the camshaft but which is oscillatable with respect to the camshaft. The vane has opposed lobes (460a, 460b) which are received in opposed recesses (432a, 432b), respectively, of the sprocket. The recesses have greater circumferential extent than the lobes to permit the vane and sprocket to oscillate with respect to one another, and thereby permit the camshaft to change in phase relative to a crankshaft whose phase relative to the sprocket is fixed by virtue of a chain drive extending therebetween. The camshaft tends to change in reaction to pulses which it experiences during its normal operation, and it is permitted to change only in a given direction, either to advance or retard, by selectively blocking or permitting the flow of hydraulic fluid, preferably engine oil, through the return lines (494, 496) from the recesses by controlling the position of a spool (500) within a valve body (498) of a control valve in response to a signal indicative of an engine operating condition from an engine control unit (508).

摘要： A variable camshaft timing arrangement for an internal combustion engine inhich a camshaft, for example, an intake valve operating camshaft in a dual camshaft engine, is advanced or retarded in its position relative to the crankshaft and to the exhaust valve operating camshaft in reaction to torque pulsations in such intake valve operating camshaft. In an engine having cam followers of the friction type, the unidirectionally acting torque on the camshaft which results from the friction between the camshaft and the followers can be offset by providing resilient means to act on one of the opposed cylinders to introduce a countertorque into the camshaft which is oppositely directed to the frictional torque.

摘要： A variable camshaft timing arrangement for an internal combustion engine in which a camshaft, for example, an intake valve operating camshaft in a dual camshaft system, is advanced or retarded in its position relative to the crankshaft and to the exhaust valve operating camshaft in reaction to torque pulsations in such intake valve operating camshaft. The other camshaft of the dual camshaft engine has a sprocket oscillatingly mounted thereon. The other camshaft also has a bracket or another sprocket keyed thereto and the bracket or another sprocket is chain driven by the rotation of the crankshaft. A pair of single acting hydraulic cylinders interconnect the oscillating sprocket and the bracket or other sprocket, with the piston ends of the cylinders pivotably attached to the oscillating sprocket and with the body ends of the cylinders pivotably attached to the other sprocket or bracket. The cylinders act in opposite directions and are hydraulically interconnected so that one extends as the other retracts and vice versa. The hydraulic system includes a control valve which is controlled by an engine controller to selectively permit one of the cylinders to extend, and the other to retract, in reaction to torque pulsations in the camshaft which is being advanced or retarded to provide desired engine operating characteristics. The bracket or other sprocket whose position is phase adjustable in this manner is connected by a chain to a sprocket which is keyed to the intake valve operating camshaft. An adaptation of the system to the synchronous phase adjustment of the positions of both camshafts of a dual camshaft engine is also specifically disclosed.

摘要： A continuously variable transmission including a driving shaft connected to an engine output member and a driven shaft. The shafts are interconnected by a stepless variable coupling. A bidirectional gear drive mechanism connects the driven shaft to a differential mechanism having two output shafts extending therefrom. The drive mechanism includes a two gear forward and a three gear reverse drive path, each of which is controlled by a fluid-actuated starting clutch mechanism. Each gear path is adapted to drive a transfer gear which continually intermeshes with a ring gear of the differential defining another gear mesh. By such construction, the output shafts and the engine output memeber may rotate in the same direction during a forward drive mode of operation.
