摘要： A hydraulic tensioner having a porous vent formed of sintered powder metal adapted to permit air to readily escape from within the tensioner while inhibiting air ingestion during cycling and limiting oil leakage. The vent is located within an aperture of the plunger near the highest point of the tensioner or at the top of the spring within the interior space of the plunger. Alternatively, the air vent may be located at the oil supply inlet before the oil enters the tensioner's fluid chamber.

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 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 hydraulic tensioner is designed for low cost and ease of manufacturing. A piston housing has a bore and a bore cup member received within the bore. A piston is slidably received within the bore cup member, forming a high pressure fluid chamber with the bore cup member. The piston housing can be constructed of inexpensive materials such as aluminum or plastic. The piston and bore cup member are constructed of drawn metal. A single channel connects the pressure chamber to an external source of fluid, and a single valve system regulates the flow of fluid into the pressure chamber. The inexpensive materials and simple design provide for a low cost hydraulic tensioner.

摘要： A compact arrangement for a continuously variable transmission and power train system is provided to be used in rear wheel drive vehicles. In one arrangement, the input shaft is in-line with the output shaft. In this arrangement, the input shaft, having a hydraulic pump, is connected to an engine by a torque converter. A first transfer gear assembly transfers power from the input shaft to the adjustable input pulley of a continuously variable transmission assembly. The adjustable input pulley transfers power to an adjustable output pulley through a belt. A second transfer gear assembly transfers power from the adjustable output pulley to an output shaft in-line with the input shaft. A forward and reverse gear system having a compound planetary gear set and clutch on the output shaft provides forward, neutral, and reverse gears.
