摘要： In a ratchet-type hydraulic tensioner for use with a timing chain of an internal combustion engine, two or more oil reservoirs gradually receive oil fed under pressure from an external source, and supply the oil through a hydraulic valve mechanism to a high pressure oil chamber formed by a plunger and a housing in which the plunger is slidable. Throttle holes, formed in partition walls separating the reservoirs, control the flow of oil from one reservoir to another. An excess oil discharge hole is optionally provided in one of the reservoirs. The invention prevents abnormal protrusion of the plunger, reduces chain noise and component damage due to wear, and rapidly re-establishes proper tension on engine start-up.

摘要： In the check valve of a hydraulic tensioner, a bell-shaped retainer is provided with plural, branched, leg portions which resiliently grip the outer surface of a ball seat. Oil induction slots are formed between adjacent branched leg portions of the retainer to provide oil flow paths that are unimpeded by the plunger-biasing spring of the tensioner.

摘要： In a ratchet-type hydraulic tensioner for a chain transmission, having a plunger and a housing forming a high pressure oil chamber, an excess supply oil discharge passage is provided. The discharge passage communicates with an oil supply passage leading from an oil supply opening, which receives oil under pressure from a oil pump, to a hydraulic check valve mechanism in the housing, which delivers oil to the high pressure oil chamber. Excess oil is discharged to the exterior of the tensioner housing and directed toward the chain. Excessive chain tension is avoided, and smooth and reliable chain travel, and suppression of whistling sounds, are achieved.

摘要： In a chain transmission, the guide-contacting portions of inner and outer plates of a chain each comprise a pair of front and rear flat surfaces, an intermediate concave oil-retaining surface and convex connecting surfaces. The lengths of the flat surfaces are such that adjacent flat surfaces of overlapping inner and outer plates overlap even when the plates in contact with the portion of a convex guide surface having the smallest radius of curvature.

摘要： A plunger stop for temporarily holding the plunger of a ratchet type chain tensioner in place during installation of the tensioner, or during mounting or removal of the chain, comprises a bifurcated part inserted into a groove in which a pivoted ratchet pawl is situated. The bifurcated part is sandwiched between the pivoted ratchet pawl and a part of the tensioner housing, with the bifurcated part straddling a ratchet pawl-biasing spring in the groove. A grip, which is integral with the bifurcated part protrudes outside the tensioner housing so that it can be grasped manually for removal.

摘要： In a transmission chain having link plates with convex edges for sliding contact with a guide surface, the plates are asymmetric in shape so that the distance from a line connecting the centers of the connecting holes and the convex edge is greatest at a position other than at the midpoint between the connecting holes. A pivoting action of the link plates takes place as they slide over a guide surface, changing the abutment point.

摘要： In a silent chain, a link plate is formed by punching, followed by simultaneous shearing of the inner surfaces of the pin holes, the inner engagement surfaces of the teeth, the outer engagement surfaces of the teeth, the connecting arc continuous with the inner connecting surfaces, and the back of the link plate over at least 70% of the plate thickness. The plates are arranged at random to form a link, and engage a sprocket first by engagement of an inner engagement surface with a sprocket tooth, and thereafter seat on the sprocket with outer engagement surfaces of the link teeth in engagement with the sprocket teeth.
