摘要： In a ring-type tensioner, an expansible elastic ring disposed in a groove formed in the wall of a plunger-accommodating hole cooperates with teeth formed on the plunger to restrict axial movement of the plunger. The ring and the groove in the wall of the plunger-accommodating hole have flat radial surfaces for mutual engagement. However the ring also has oblique plunger-tooth engaging surfaces. The ring has manipulable end parts that can be locked in fixed relation to each other by a tool to secure the plunger against axial movement. The tool can also be inserted into a gap between the manipulable end parts to expand the ring and thereby release the plunger.

摘要： In a chain tensioner, an expansible ring is disposed in an internal groove formed in the inner wall of a plunger-accommodating hole near an open end thereof. The ring cooperates with grooves formed on the plunger to exert a ratchet action. The relationship between the angles of the surfaces of the internal groove and the grooves on the plunger allows the plunger to protrude, restricts retraction of the plunger on start-up of a chain transmission, but allows retraction when chain tension becomes excessive. In one embodiment, in which the ring is a C-ring, the tensioner housing can be formed with external threads for mounting in a threaded hole on a timing chain cover or other engine part. In other embodiments, the ring can have externally protruding levers for manipulation of the ring.

摘要： This invention provides a chain tensioner that is compact, excellent in operation, easy to maintain and handle and low in manufacturing cost. This chain tensioner has a tubular housing 1 having a bottom, a plunger 3 installed in the inner periphery 1a of the housing so as to smoothly slide inside the housing, a return spring 5 providing the plunger 3 with a force pushing outward, a plurality of latching grooves 33a–33d formed on the outer periphery of the plunger 3, a resister ring 7 capable of locking in the latching grooves, and a check valve 6 that is mounted on the bottom of the housing inner periphery 1a, provides the housing inner periphery 1a with operating oil and prevents its reverse flow. The range of backward movement of the plunger 3 is limited by mating the resister ring 7 locked in the latching grooves 33a–33d with a first stopper 21 formed on the housing inner periphery 1a.

摘要： A tensioning device is provided for an endless drive device, having a housing, a spring-loadable tensioning piston in a piston bore of the housing, a transport locking device, and a device to adjust the working range of the tensioning piston with a retainer element on the housing having at least one spring arm and a retainer profile arranged in the forward section of the tensioning piston in the tensioning direction. The transport locking device comprises a transport groove in the tensioning piston, the spring arm of the retainer element being engageable into the transport groove, and an unlocking element, wherein the unlocking element has at least one ramp section potentially in functional contact with the spring arm. The ramp section exerts an unlocking force on the spring arm over a travel path of the unlocking element relative to the tensioning piston, forcing said spring arm out of the transport groove.
