摘要： In a hydraulic tensioner (100), an oil pressure control recess (124), at a proximal end (121a) of a cylindrical, plunger-receiving hole (121), receives from an oil supply, and also receives oil which oozes past a check valve and an inner sleeve (150) inside the plunger (110), thereby returning the oil, which would leak to the outside in a conventional hydraulic tensioner, to the interior of the plunger (110).

摘要： The present invention provides a hydraulic tensioner with a ratchet mechanism simple in structure. The hydraulic tensioner (1) includes a hollow plunger (3) that is slidably received in a bore (2a) of the housing (2) that has an inner space (3a) defining a fluid chamber (20) with the bore (2a) and a rack member (7) provided slidably in axial direction in a groove (3b) on an outer circumference of the plunger (3). The hydraulic tensioner (1) further includes a spring (4) biasing the plunger (3) in a protruding direction, a ratchet member (8) that that is provided slidably in a ratchet hole (2b) extending in an inclined direction intersecting an axis (L) of the plunger (3) and that has a cylindrical head portion (88) adapted to engage rack teeth (7a) of the rack member (7), permitting travel of the plunger (3) in a protruding direction but preventing retraction of the plunger (3) in a backward direction, and a coil spring (85) that biases the ratchet member (8) in an engaging direction of the rack teeth (7a) with an outer circumferential edge portion (80a) of the distal end of the head portion (80).

摘要： A timing belt antotensioner includes a mechanism actuated by the reversal of timing belt movement direction. In automotive applications reversal of timing belt direction occurs only rarely under inadvertent or accidental circumstances. Such reversals can cause belt slackening sufficient for a toothed belt to jump gear teeth thereby changing engine cam shaft timing. Four related mechanisms are disclosed, each of which will, upon actuation by belt reversal cause the autotensioner pulley axis of rotation to move in a direction that tightens the belt during reverse movement of the belt. Thus, the belt remains tight to the toothed pulleys preventing jump or skip of the belt until the belt returns to proper forward belt movement.

摘要： A chain drive assembly for an internal combustion engine comprises a chain tensioner (6) that acts upon a chain (2) that is used to drive the cam shafts (4) of the engine. The tensioner has a hydraulically actuated plunger (30) which is moveable within a housing and biasing means in the form of a solenoid (34), compression spring or motor that urges the plunger outwards of the housing at least when there is no hydraulic pressure. The tensioner is controlled by means of a control unit (8) that receives signals from various transducers that transmit signals providing information in relation to the performance of the engine. The control unit receives the measured information, calculates the desired tension to be applied to the chain and transmits the control signal to the chain tensioner so as to operate the biasing means or control the hydraulic pressure so that the desired chain tension is applied.

摘要： A hydraulic tensioner (100) is designed for low cost and ease of manufacturing. A housing (102) has a bore (104) and a sleeve member (105) received within the bore. A piston (130) is slidably received within the sleeve member, forming a high pressure fluid chamber (180) with the sleeve member. The housing can be constructed of inexpensive materials such as aluminum or plastic. The piston and sleeve member are constructed of drawn metal. The housing may be formed by injection molding. The sleeve member and other components of the tensioner may be assembled within the tensioner by inserting them into the mold during the injection molding process.
