摘要： An auto-tensioner for engine accessories is proposed which can smoothly follow shrinkage and expansion of a belt and which can minimize the amplitude of vibration of the belt. A seal member 13 is mounted to a cylinder 11 at its top open end. A rod 16 slidably extends through the seal member 13. A return spring 21 biases the rod 16 outwardly. A plunger 24 is slidably received in a sleeve 12 having a bottom and received in the cylinder 11, and is connected to the bottom of the rod 16. The plunger 24 has a passage 27 through which a lower pressure chamber 25 and an upper reservoir chamber 26 communicate with each other. A check valve 28 is provided at the passage 27. A return chamber 29 is defined under the sleeve 12 so as to communicate with the reservoir chamber 26. In the bottom of the sleeve 12, a valve hole 31 is formed through which the return chamber 29 communicates with the pressure chamber 25. A relief valve 32 is provided at the valve hole 31. The relief valve 32 prevents the pressure in the pressure chamber 25 from rising above a set pressure, thereby preventing an excessive increase in the tension of the belt. This makes it possible to reduce oil leak gaps defined between the sliding surfaces of the sleeve 12 and the plunger 24, thereby keeping the vibration amplitude of the belt. This improves the responsiveness of the auto-tensioner to the expansion of the belt while the relief valve 32 is open.

摘要： In a tension adjusting device for an engine accessory driving belt by tightening a bolt 7 threaded into an engine block 8, a fulcrum shaft 6 is fixed. A tension pulley 1 is rotatably supported by a pulley arm 2 pivotally supported about the fulcrum shaft 6. A regulating force of a hydraulic auto-tensioner is applied to the pulley arm 2 to press the tension pulley against the belt B. A washer 10 is disposed between a boss 3 formed on the pulley arm 2 and the head 7a of the bolt 7. The washer 10 has an outer cylindrical portion 11 covering one end of the boss 3. A slinger 12 is mounted on the end of the boss 3 to define a labyrinth 13 between the slinger 12 and the cylindrical portion 11, thereby preventing entry of muddy water and dust into the bearing portion pivotally supporting the pulley arm 2.

摘要： Contact between the top portion and the spherical seat of the piston is avoided through a simple arrangement and even if the swash plate angle is increased, a suitable contact portion is obtained. To this end, the top portion of a shoe for swash plate type compressors is composed of a partial spherical surface having a larger radius of curvature than that of the outer peripheral surface which contacts a seat surface formed in the piston, the top portion being smoothly continuous with the outer peripheral surface. Further, the generatrix of the outer peripheral surface of the shoe in contact with the seat surface is an arc whose center of curvature is radially spaced from the centerline of the shoe and whose radius of curvature is shorter than that of the seat surface, whereby the outer peripheral surface of the shoe contacts the seat surface of the piston at a predetermined position; this makes it easier to control the contact of the shoe for swash plate type compressors.

摘要： A hydraulic auto-tensioner includes a cylinder containing hydraulic oil, a rod inserted in the cylinder, and two coupling pieces mounted to the bottom of the cylinder and the top end of the rod, respectively. A support ring is inserted in the mounting hole of each coupling piece, and a bush is inserted in the support ring. One of the radially inner surface of the mounting hole and the radially outer surface of the support ring is a curved surface such that the support ring is alignable. Radially outwardly extending flanges are formed at one end of the support ring and at the other end of the bush such that the flanges axially face the respective end surfaces of the coupling piece with gaps left therebetween. A coupling arrangement is provided between the support ring and the bush which is adapted to engage both the support ring and the bush when the bush is inserted into the support ring, thereby axially inseparably coupling them together.

摘要： An object of the present invention, in an idler pulley having a pulley main body formed of steel sheet, is to prevent the pulley main body and the outer ring of a bearing from creeping and the pulley main body from slipping off. An idler pulley according to the invention comprises a pulley main body adapted to have a belt entrained therearound, a ball bearing fitted in the pulley main body, and a shaft member fitted in the inner ring of the ball bearing, wherein a layer of a soft metal whose Young's modulus is lower than those of the pulley main body and the outer ring of the bearing is interposed between the inner surface of the pulley main body of steel sheet and the outer surface of the outer ring of the bearing. When a belt is entrained, this soft metal layer elastically deforms to thereby function to fill a clearance which develops between the pulley main body and the outer ring of the bearing, thereby minimizing the decrease of the joining force between the pulley main body and the outer ring of the bearing, thus preventing drawbacks, such as creep, from occurring.
