摘要： For preventing very small amplitude vibrations of the rod in a tensioner during high speed movement of a belt to be tensioned by the tensioner, a tube which is connected to a plunger which moves together with the rod is overlapped with a stationary member so as to define an annular clearance therebetween in an operating chamber of the tensioner. By filling an operating fluid in the clearance, shear strain is generated upon high speed movement of the plunger, which resists movement of the plunger.

摘要： A hermetically sealed autotensioner used for adjusting tension of engine belts comprises a cylinder, a plunger slidably fitted in the cylinder and having a rod projeced from the cylinder, a free piston slidably fitted in the cylinder, and a rod guide fitted in the tip portion of the cylinder so as to slidably support the rod. When a large thrust force acts on the rod, the rod guide serves as a bearing for the rod so that no scuffing or rocking motion occurs between the cylinder and the plunger.

摘要： A tensioner for vehicle belts produces reduced rattling because radial forces are not transferred to the plunger. A tensioner body has a columnar hole extending from an open end toward a closed end. The plunger is fitted into the columnar hole and separates the columnar hole into first and second chambers. The plunger has sufficient clearance with respect to the body to permit restricted passage of fluid between the chambers. A rod pressed by the belt extends into the columnar hole and presses the plunger against the biasing force of a spring. In order to reduce the transfer of radial forces from the rod to the plunger, either the lower surface of the rod or the upper surface of the plunger is formed in a semi-spherical shape.

摘要： A cylinder control device for a variable-cylindered engine. The device comprises a body slidable within a bore formed in a block and urged by a spring always in contact with a cam, a plunger mounted in the body and slidable by hydraulic pressure in the direction perpendicular to the direction of sliding of the body, the plunger having a groove which is adapted to be engaged by the upper end of a valve stem 40 and an escape bore which is adapted to be positioned right above the upper end of the valve stem when the plunger is slided to a cylinder-inoperative position; and means for controlling said application of the hydraulic pressure to the plunger under the control of a computer. When the computer provides an instruction for normal operation of the cylinder, the plunger is held at a position where the upper end of the valve stem engages with the groove in the plunger so that, when the cam is rotated, the valve stem is depressed through the body thereby to open the valve port, whereas, when the hydraulic pressure is applied to the plunger so as to urge the plunger to a valve-inoperative position, the upper end of the valve stem escapes into the escape bore in the plunger when the body is depressed by the cam, so that the valve stem is not depressed and the valve is kept closed, thereby keeping the cylinder inoperative.

摘要： An automatic tensioner for adjusting the tension in a timing belt, V belt, or the like has a locking mechanism. The tensioner has a plunger always biased toward a large oil chamber containing oil. A rod having a head that is pressed against the timing belt or the like is inserted in the body of the tensioner so as to form a small oil chamber. A piston is received in the body of the tensioner. Normally, the piston bears against the plunger. If oil should leak from the large oil chamber, then the plunger will move downward, permitting the piston to engage the rod. Thus, the rod is locked.
