摘要： A hydraulic tensioner (100) having a piston (130) slidably received in a housing bore (104) and biased in a protruding direction by a spring (170). A pressure relief valve (300) is positioned in the nose of the piston (130). The pressure relief valve (300) includes a valve member (302) and seat member (306). The valve member (302) biased by a spring (316) disposed between the seat member (306) and a retaining plate (310) on the valve member (302).

摘要： A hydraulic tensioner includes a piston that is pivotally mounted to a tensioner arm. The piston is slidably received within a hollow body that is pivotally mounted to a mounting block or engine. In different embodiments, the body is mounted to the tensioner arm while the piston is biased against the mounting block or pivotally connected to the mounting block or engine.

摘要： A hydraulic tensioner (10) having a porous vent (70) formed of sintered powder metal adapted to permit air to readily escape from within the tensioner (10) while inhibiting air ingestion during cycling and limiting oil leakage. The vent (70) is located within an aperture (46) of the plunger (40) near the highest point of the tensioner or at the top of the spring (60) within the interior space of the plunger (40). Alternatively, the air vent (70) may be located at the oil supply inlet (24) before the oil enters the tensioner's fluid chamber (22).
