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 tensioner lever assembly for a chain transmission, an auxiliary lever, arranged to pivot relative to a main tensioner lever, engages a free span of the chain approaching the main lever from a driving sprocket. The auxiliary lever can be pivoted coaxially with the main lever, and can extend either toward the center of the main lever, or toward the driving sprocket. Alternatively, the auxiliary lever can be pivoted on the main lever at a location remote from the pivot axis of the main lever, and engaged with a free span of the chain moving away from the main tensioner lever and approaching a driven sprocket.

摘要： A guide for an engine timing chain comprises a shoe mounted on a guide body, and having opposed, chain-restricting, side walls integrally molded with a chain-contacting shoe bottom. Each wall comprise a low portion, and an outwardly stepped high portion. The height of the low portion less than the distance between the connecting pins of the chain and the chain-contacting surface of the shoe bottom. The height of the high portion, however, is greater than the distance between the connecting pins and the chain-contacting surface. The high portion of each wall is stepped outward sufficiently to provide a clearance between the end of a connecting pin and the inwardly facing side of the high portion when the adjacent outer link plate of the chain is in contact with the corresponding low portion. The height of the high portion, however is greater than the overall height of the timing chain.

摘要： A plastic movable guide for a chain or other traveling transmission medium, comprises a guide body composed of a shoe and a slotted plate-receiving portion integrally molded as a unit from a resin, and a reinforcing plate inserted into the slot. A mounting hole adjacent one end of the guide body is aligned with a hole adjacent one end of the reinforcing plate. The diameter of the hole in the reinforcing plate is larger than the diameter of the mounting hole in the guide body, so that the inner periphery of the hole in the reinforcing plate does not extend inward past the edge of the mounting hole. The guide so configured exhibits excellent quietness and assembly efficiency and can be produced at a relatively low cost.

摘要： A plastic movable guide for a belt or chain transmission has a plunger-engaging portion for contact with the plunger of a tensioner at a location remote from its pivot axis. A reinforcing plate is located in a slot in a resin guide body, and is slightly recessed at the location of the plunger-engaging portion so that it does not protrude from the slot opening and is not contacted by the plunger of the tensioner. Superior quietness of operation, ease of assembly, and reduction of production cost are achieved.

摘要： A ratchet tensioner includes a plunger releasing mechanism for turning a ratchet pawl against the force of a plunger spring to disengage a locking prong of the ratchet pawl from a rack tooth of a plunger. The plunger releasing mechanism has a pin insertion hole formed in a plunger housing transversely across a recessed groove formed in the housing for mounting the ratchet pawl, and a sloped surface formed on the ratchet pawl and normally extending obliquely across the axis of the pin insertion hole. The sloped surface, upon abutment with the tip end of a pin which is inserted in the pin insertion hole, is capable of causing the ratchet pawl to turn against the force of the ratchet spring to thereby disengage the locking prong of the ratchet pawl from the rack tooth of the plunger for releasing the plunger.

摘要： A ratchet tensioner includes a plunger locking and releasing mechanism for selectively locking and releasing a plunger relatively to a ratchet pawl pivotally mounted to a housing. The plunger locking and releasing mechanism has a lever-like pin contact portion formed integrally with a ratchet pawl body, a pin member-fitting hole formed in two opposed side walls of the housing in registry with the lever-like pin contact portion such that there being two pin-accommodating spaces defined between the lever-like pin contact portion and an inner peripheral surface of the pin member-fitting hole on opposite sides of the lever-like pin contact portion, and a pin member removably and selectively inserted in the pin-accommodating spaces. When the pin member is inserted in one of the two pin-accommodating spaces, the ratchet pawl body is turned in one direction to keep the engagement between the ratchet pawl and ratchet teeth formed on the plunger, thereby locking the plunger in position against movement relative to the housing, and when the pin member is inserted in the other pin-accommodating space, the ratchet pawl body is turned in the opposite direction to disengage the ratchet pawl from the ratchet teeth on the plunger against the force of a ratchet pawl spring, thereby allowing the plunger to project outward from the housing by the force of a plunger spring.

摘要： In an engine timing chain guide composed of a synthetic resin shoe supported on a frame by L-shaped and strip-shaped engagement members integrally molded as unitary parts of the shoe, the L-shaped members are formed with oblique tongues that resiliently engage side edges of the frame member, and the strip-shaped engagement members include surfaces that extend obliquely toward, and resiliently engage, a side edge of the frame member. Laterally extending legs of the L-shaped members are also formed with bulged portions, and the frame member is sandwiched between the bulged portions and a back side of the shoe.
