摘要： A hydraulic tensioning device, which is used in traction drives of internal combustion engines and which includes a piston (19) that is supplied with a hydraulic fluid, is provided. The piston is movably guided in a linear manner in a cylinder and is spring-loaded against a traction device. The hydraulic fluid can flow into a pressure chamber (17) via a non-return valve or out of the pressure chamber (17) via a pressure-relief valve (20), depending on an adjustment movement direction of the piston (19). For this purpose, the pressure-relief valve (20) is inserted in a central receiving area (16) of the piston (19) on the pressure-chamber side as a premountable valve group (21) and includes a pot-shaped valve housing (18) and into which a guide element (25) with a corresponding valve seat (29), a valve element designed as a valve plate (30), and a pressure spring (31) are integrated.

摘要： To provide a tensioner which can circulate a sufficient amount of oil even if there is a long time lag until pressurized oil starts to be supplied, and which exhibits a lower level of leak of oil stored therein, and which is structured simply without increasing the number of components therefore. The tensioner includes: a tensioner body having a plunger bore; a cylindrical plunger slidably inserted into the plunger bore; and biasing means for urging the plunger outward. When the tensioner is fixed to a wall surface, a body hole that extends from the wall surface up to a circumferential surface of the plunger bore is located lower than an oil discharge hole in the wall surface.

摘要： A tensioner for an engine accessory drive system includes a tensioner arm pivotally mounted for movement between a free arm position and a load stop position. The tensioner arm includes a pulley which engages a belt. A piston, disposed in a cylinder, is pivotally linked to the tensioner arm. A spring urges the tensioner arm towards the free arm position. A moveable load stop member, controlled by an actuator, projects into the cylinder. The load stop member abuts the piston to thereby arrest movement of the tensioner arm and define the load stop position. The actuator may drive the load stop member against the piston to move the tensioner arm towards the free arm position so as to increase belt tension.
