摘要： A variable cam timing phaser for an internal combustion engine with at least one camshaft includes a housing (144), a rotor (138), and a phaser control valve (168). The phase control valve is offset from a center axis of rotation through the camshaft of the phaser and may also be parallel to the center axis of rotation. The phaser control valve directs fluid flow to shift the relative angular position of the rotor relative to the housing. The phaser may be cam torque actuated, oil pressure actuated, or torsion assist.

摘要： A phaser comprising a housing, a rotor, and first and second passages. The housing has at least one chamber defined by an advance wall, an arcuate outer wall, and a retard wall. The rotor has at least one vane projecting from an outer circumference, separating the chamber in the housing into advance and retard chambers. The first passage facilitates fluid communication to a first port in the advance or retard chamber and a second passage to a second port in the other advance or retard chambers. Each port is spaced apart form the first wall or second wall of the vane, such that when the vane is moved towards the advance or retard wall of the chamber far enough, the passages are obstructed by the housing and fluid flow to the passages is restricted, such that impact of the vane with the walls of the chamber is cushioned.

摘要： A variable camshaft timing system having a camshaft with a vane-type rotor, where oscillation of the housing relative to the vane is actuated by pressurized engine oil, derived in part from a torque pulse in the camshaft. An annular locking plate is positioned coaxially with the camshaft and the housing. It is moveable relative to the housing along the longitudinal central axis of the camshaft between two positions, the teeth on the locking plate engaging the teeth on the housing and where the teeth on the locking plate are disengaged from the teeth on the housing, each position preventing circumferential movement of the housing relative to the rotor. The locking plate is biased by a plurality of metallic straps towards engagement of the teeth on locking plate with the teeth on the housing. The straps have one end secured to the locking plate and another end secured to the rotor.

摘要： A variable camshaft timing phaser for an internal combustion engine that varies rotation phase including a housing, a rotor, a locking pin, and a piston. The locking pin is moveable in a first direction, which urges a tapered end of the locking pin to engage a tapered recess in the rotor, and a second direction, opposite the first direction, to disengage the rotor. The is driven by an engine output in synchronism with the engine revolutions, the rotor is connected to the camshaft and has a fluid passage connecting a source of engine oil to the tapered recess in the rotor. The piston is located within the fluid passage and has a piston surface contacting the locking pin. The piston has a cross-section that is less than the cross-section of the locking pin, and blocks the fluid passage when the locking pin is locked, moving to a position which allows fluid to pass by the piston in the recess and press on the locking pin, so that higher pressure is required to unlock the locking pin than to hold it in its unlocked position.
摘要翻译：用于内燃机的可变凸轮轴正时相位器，其改变包括壳体，转子，锁定销和活塞的旋转相位。锁定销可沿第一方向移动，该第一方向推动锁定销的锥形端部与转子中的锥形凹部以及与第一方向相反的第二方向接合以使转子脱离。由发动机输出与发动机转数同步地驱动，转子连接到凸轮轴，并且具有将发动机油源连接到转子中的锥形凹部的流体通道。活塞位于流体通道内并且具有接触锁定销的活塞表面。活塞具有小于锁定销的横截面的横截面，并且当锁定销被锁定时阻塞流体通道，移动到允许流体在活塞中在凹部中通过的位置并且被按压锁定销，因此需要更高的压力来解锁锁定销，而不是将其保持在其解锁位置。

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.
