摘要： Disclosed is a variable valve mechanism for an internal combustion engine. The variable valve mechanism accurately adjusts the valve operating angle although its structure is simple. The variable valve mechanism includes a control pin 48, which is inserted into a pin insertion hole 38 in a control shaft 16; a bearing hole 44, which is formed in a control member 26; and an adjustment pin 50, which is rotatably supported by the bearing hole 44. The adjustment pin 50 comes into surface contact with the control pin 48 to inhibit the control member 26 from rotating relative to the control shaft 16. The valve operating angle is adjusted by replacing the adjustment pin 50 with another having a different dimension B. Such adjustment pin replacement changes the distance A between the center line of the bearing hole 44 and the center line of the control pin 48, thereby changing the relative angle θ between the control shaft 16 and control member 26. When the adjustment pin 50 rotates within the bearing hole 44, the surface contact between the adjustment pin 50 and control pin 48 is maintained irrespective of the magnitude of the relative angle θ.

摘要： An internal combustion engine including a variable valve mechanism that can avoid an unnecessary friction increase while preventing a hydraulic lash adjuster from pumping up. When a first engine speed is a critical rotation speed at which the inertia force of the variable valve mechanism exceeds the maximum load on a lost motion spring and a second engine speed is a critical rotation speed at which the inertia force of a valve and rocker arm exceeds the maximum load on a valve spring, the maximum loads are set such that the first engine speed is lower than the second engine speed.

摘要： A valve drive system comprises a power transmitting mechanism (13) that converts rotary motion of an electric motor (12) into opening and closing motion of an intake valve (3) provided in a cylinder (2) of an internal combustion engine (1) to transmit power from the electric motor (12) to the valve (3) via a cam (152); and a rotational angle restricting mechanism (16) that is provided in a motion transmission path that extends from the electric motor (12) to the cam (152) and restricts rotation of the cam (152) within a predetermined angular range that is set so that a piston (5) of the engine (1) and the intake valve (3) do not interfere with each other. The rotational angle restricting mechanism (16) comprises a flange (161) that rotates as a unit with a camshaft (151) and forms a slotted groove hole (161a) thereon; and a stopper pin (162) that is inserted into and retracted from the groove hole (161a).

摘要： The rotary motion of a camshaft is transmitted from a first drive cam to a slide surface of a swing cam arm via intermediate members so that the swing cam arm lifts a valve. In this instance, the operating characteristic of the valve changes when the rotation position of a control shaft changes to change the positions of the intermediate members on the slide surface. When the operating characteristic control mode for the valve is to be changed from variable control to fixed control, coupling means couples the swing cam arm and input arm, thereby causing a second drive cam to swing the swing cam arm. The setting for the lift amount of the valve that is obtained when the second drive cam swings the swing cam arm is not smaller than a maximum lift amount setting for a situation where the first drive cam swings the swing cam arm.

摘要： Disclosed is a valve mechanism for an internal combustion engine that uses a motor to open/close a valve body of each cylinder. The valve mechanism includes a camshaft that is rotated by the motor and equipped with cams for driving the valve body of a plurality of cylinders; control means that drives the motor while making a mode switch between a normal rotation drive mode in which the camshaft is continuously rotated in one direction to drive the valve body and a swing drive mode in which the camshaft is swung to drive the valve body; and change means that changes the relative angular positions of cylinder-specific cams on the camshaft.

摘要： Engine starting apparatus comprising a one way clutch. A first oil seal is located on the outer side of a second oil seal in the radial direction of a ring gear. Upon starting of an engine, the time that the first oil seal is slid on the ring gear is short, and after the start of the engine, the first oil seal is not slid on the ring gear. The second oil seal is located on the inner side of the first oil seal in the radial direction of the ring gear. Therefore, the second oil seal hardly deteriorates even if slid on a flywheel at high speed after the start of the engine. By locating the first and second oil seals at different positions in the radial direction of the ring gear, it is possible to improve the startability and the lifetime of a starting apparatus. At least one oil seal has a taper shape in order to generate a thrust force which forces the ring gear away from the flywheel.
摘要翻译：发动机起动装置，包括单向离合器。第一油封位于第二油封的外侧沿齿圈的径向方向。发动机起动时，第一油封在齿圈上滑动的时间短，在发动机起动之后，第一油封不会在齿圈上滑动。第二油封沿着齿圈的径向位于第一油封的内侧。因此，即使在发动机起动之后高速地在飞轮上滑动，第二油封也几乎不劣化。通过将第一和第二油封定位在环形齿轮的径向上的不同位置，可以提高起动装置的起动性和使用寿命。至少一个油封具有锥形形状，以产生迫使齿圈远离飞轮的推力。

摘要： The present invention relates to a variable valve operating device and makes it possible to reduce the loss in driving force transmission from a camshaft to a valve during a valve lift.The rotary motion of a drive cam 122 is transmitted to a swing member 140 via intermediate rollers 172, 174. A coupling member 164 couples the intermediate rollers 172, 174 to a swing fulcrum 166 that is fastened to a control shaft 132. The swing fulcrum 166 is positioned eccentrically to the center of the control shaft 132. Further, when the control shaft 132 is positioned at a predetermined rotation position, the swing fulcrum 166 is positioned so that the control shaft 132 is placed between the swing fulcrum 166 and the intermediate rollers 172, 174. Preferably, the swing fulcrum 166, the control shaft 132, and the intermediate rollers 172, 174 are aligned.
