    Abstract: A tensioner comprising a piston slidably received within a piston bore of the housing having a plurality of grooves formed on an outer circumference, the piston forming a first pressure chamber with the piston bore. The tensioner uses a mechanism to remove a sliding pawl or expandable clip from engaging the grooves on the piston, such that the piston can move towards the housing and reduce chain load when fluid pressure is reduced in the first pressure chamber during engine shutdown, but not so much as to leave the chain uncontrolled during engine restart. The mechanism may for example be a fluid biased spool piston which engages the expandable clip or a pawl piston that engages a sliding pawl.

    Abstract translation: 一种张紧器，包括可滑动地容纳在所述壳体的活塞孔内的活塞，所述活塞孔具有形成在外周上的多个槽，所述活塞与所述活塞孔形成第一压力室。 张紧器使用机构来移除滑动爪或可膨胀夹与接合活塞上的凹槽，使得当发动机关闭期间流体压力在第一压力室中减小时，活塞可以向壳体移动并减小链条负载，但不 在发动机重新启动期间，使链条不受控制。 该机构可以例如是与可膨胀夹或接合滑动爪的棘爪活塞接合的流体偏压卷轴活塞。

    Abstract: A parking mechanism located on a final drive or primary drive of a vehicle to engage or disengage an output shaft connected to wheels of the vehicle. The parking mechanism includes a back drive chain on the final drive or primary drive that engages with a parking pawl. A cam assembly biases the parking pawl to engage with the back drive chain to prevent rotation of the wheels.

    Abstract: A hydraulic tensioner (10) and method of manufacture can include a housing (12), a piston (16) moveable from a retracted position toward an extended position with respect to the housing (12) in response to fluid pressure, and a tensioner spring (36) biasing the piston (16) toward the extended position. The hydraulic tensioner (10) can include a modular sleeve (14) supported by the housing (12) and defining an aperture (15) for slidably receiving the piston (16) and defining an expandable fluid chamber (18). The housing (12) can provide a fluid passage (39) for fluid communication between the expandable fluid chamber (18) and a source of pressurized fluid. The housing (12) can have a seat (25) in fluid communication with the aperture (15). An end (38) of the modular sleeve (14) can be seated with respect to a seat (25) of the housing (12) to seal the fluid passage (39).
