摘要： Deaeration of the high pressure oil chamber of a hydraulic tensioner takes place though a helical orifice formed by opposed flanks of the threads of a threaded hole in the tensioner housing and the threads of a screw inserted into the hole. The opposed flanks are maintained in spaced relationship by a force exerted by a spring washer disposed between the head of the screw and a surface of the tensioner housing surrounding the opening of the threaded hole. The flank of the thread of the hole that forms part of the boundary of the helical orifice can have a concave curvature in order to increase the aperture of the air flow path. A groove in the surface surrounding the opening of the threaded hole prevents the washer from sealing off the flow of air. This groove is disposed with its exit end at a level above its entry end.

摘要： An air bleeding valve includes an annular valve element for removing air from oil contained in a hydraulic circuit of a hydraulic tensioner and for suppressing the removal of the oil. An air bleeding valve body is fitted in an air bleeding valve accommodating hole formed in the hydraulic tensioner. A circumferential groove having a rectangular cross section is formed on an outer circumferential surface of the air bleeding valve body. The annular valve element having a rectangular cross section is fitted in the circumferential groove so as to be movable in an axial direction parallel to the axis of the annular valve element, and displaceable in a radial direction toward and away from the axis of the annular valve element. Such air bleeding valve removes air in a hydraulic circuit while suppressing the removal of oil in the hydraulic circuit during starting operation of an engine.

摘要： In a hydraulic tensioner, a deairing valve unit comprising a synthetic resin ball guide, a check ball a biasing spring, a ball seat, and a retaining disc, is press-fit into a hollow plunger, and disposed adjacent the protruding end of the plunger. The ball and seat of the deairing valve unit are arranged to block flow of oil out of the tensioner when the oil is under pressure, but open to allow air to flow out of the tensioner, through a vent in the protruding end of the plunger, after a negative pressure condition occurs inside the oil chamber of the tensioner.

摘要： A tensioner (10) for an endless loop power transmission member can include a piston (12) operably engageable with an endless loop power transmission member, and a cylinder (14) guiding the piston (12) for sliding coaxial movement in a direction of the endless loop power transmission member. The piston (12) and cylinder (14) defining an oil reservoir or pressure chamber (26) for receiving hydraulic fluid. A bearing (28) has bearing balls (30) located in a counter bore (32) coaxial with cylinder bore (34). The counter bore (32) has a steep taper (36) on which the bearing balls (30) ride. As the cylinder (14) moves in an extending direction, the bearing balls (30) move out of the counter bore (32) allowing free extending movement of the cylinder (14). As the cylinder (14) moves in a retracting direction, the bearing balls (30) are driven down into the steep taper (36) preventing the cylinder (14) from retracting.

摘要： A push-to-release mechanism may be reset to a shipping condition from any piston position by opening a ratchet clip by applying an external force on the ratchet clip legs. A tensioner with a push-to-release mechanism includes a piston housing, a piston, a piston spring, and a ratchet clip. When the piston is released with the ratchet clip contacting a reset portion of the ratchet groove of the piston housing and axially aligned with one of the tooth grooves of the piston, the ratchet clip is captured between one of the piston teeth of the piston and the reset portion of the piston housing in a shipping condition. Methods of placing the tensioner in the shipping condition and releasing the tensioner from the shipping condition are also disclosed.
