摘要： In a hydraulic tensioner having a coiled plunger-biasing spring, the volume of the high pressure oil chamber is reduced by incorporating a bar inside the spring. One of both ends of the spring are formed to block passage of the bar, so that the bar and spring can be installed as a pre-assembled unit, and dropping of the bar out of the spring can be avoided.

摘要： A transmission guide comprises a synthetic resin shoe and a more rigid synthetic resin base, integrally molded by two-member molding. The base is formed with a pair of spaced, opposed, side walls extending in the direction of elongation of the base along opposite edges of a shoe-supporting surface of the base. These side walls engage respective side edges of the shoe, and extend past the front surface of the shoe so that they can restrict lateral movement of a transmission chain sliding along the front surface of the shoe. Indentations in the side walls receive protrusions formed on the edges of the shoe. Edges of the openings of the indentations are chamfered or convexly curved to avoid interference with the movement of the chain along the guide.

摘要： In a chain guide mechanism, fixed and movable guides are attached to a guide bridge by cooperation of bosses on the guides with boss-receiving holes formed in spaced-apart elements of arms of the bridge. A fixed guide is held against rotation by cooperation of a projection on its mounting boss with a notch in a boss-receiving hole in a guide bridge arm element. A base, extending from an intermediate location at which the arms come together has a pressing structure that engages bosses on a driving sprocket, and a groove for receiving teeth of the driving sprocket.

摘要： The hollow plunger of a hydraulic tensioner, slidably receives a sleeve that divides the high pressure oil chamber into two parts. The first part is formed by the plunger and a plunger-accommodating hole of the tensioner housing. The second part is formed by the plunger and the sleeve. Two springs, one being in the first part, and the other being in the second part, urge the plunger in the protruding direction. When the second part is filled with oil during ordinary engine operation, a negative pressure in the second part exerts a force opposing protruding movement of the plunger. Therefore, the springs can be made strong enough to prevent excessive chain vibration and noise during engine start-up when the parts of the high pressure oil chamber are not filled with oil, without causing the tensioner to exert excessive force on the chain during ordinary engine operation.

摘要： A guide for a traveling transmission medium such as a timing chain comprises a resin shoe for sliding contact with the transmission medium, supported on a base frame having an two flanges and a web in an I-shaped cross-section. The base frame is produced from aluminum by die casting, using a three-part mold. Two parts of the mold cooperate to form a part of the mold cavity that forms one of the flanges and the web of the base frame, and a third part of the mold cooperates with the first two parts to form a part of the cavity in which the other flange of the base frame is formed without a draft.
