摘要： In a decompression braking apparatus which is applicable to a Diesel engine and is capable of switching an engine braking condition so as to achieve an engine revolution speed area when a decompression braking request is issued, a sleeve portion of an eccentric bushing member is pivotally interposed between an inner periphery of a rocker arm and an outer periphery of a rocker shaft fitted into the rocker arm so as to be enabled to displace a swing center of the rocker arm toward a downward direction aligned with an open direction of an exhaust valve whose degree of openings in a closure stroke thereof is varied, a first actuator is so constructed and arranged as to actuate the eccentric bushing member to be pivoted so that the swing center of the rocker arm is displaced to a second position at which the degree of openings of the exhaust valve in the closure stroke is relatively large and a second actuator is so constructed and arranged as to limit the pivotal movement of the eccentric bushing member according to the actuation by means of the first actuator so that the swing center of the rocker arm is displaced to a first position at which the degree of openings of the exhaust valve during the closure stroke is relatively small.

摘要： A relative angular phase between a timing sprocket 1 and a camshaft 2 is changed by rotating a vane rotor 3 in a normal-rotation direction or in a reverse-rotation direction by way of relative application of hydraulic pressure to one of a timing-advance phase hydraulic pressure chamber 32 and a timing-retard phase hydraulic pressure chamber 33 both defined in a housing 6 and relative release of hydraulic pressure from the other of the hydraulic pressure chambers, in order to vary the opening and closing timing of an intake valve. A restricting mechanism 10 is also provided for reverse rotation of the vane rotor, which may occur during rotating from the timing-retard phase to the timing advance phase owing to a positive fluctuating torque of the camshaft. In the restricting mechanism, a plunger 52 is projected outward by way of a hydraulic pressure supplied to a high-pressure chamber 54, so that the plunger is constantly in abutted-contact with one side wall 13a, and whereby the plunger 52 produces a pushing a force or thrust by virtue of a check valve 56, so as to counteract the positive fluctuating torque. A turning-back phenomenon of the vane rotor can be restricted in presence of torque fluctuations of the camshaft during rotation of the vane rotor, thus enhancing the responsiveness of valve timing control.

摘要： A decompression brake device comprises a valve drive mechanism for driving an exhaust valve of an internal combustion engine. The valve drive mechanism has first, second and third conditions, the first condition being a condition wherein the exhaust valve assumes a fully closed rest position during intake, compression and expansion strokes of the engine and a full open position during an exhaust stroke of the engine, the second condition being a condition wherein the exhaust valve assumes the fully closed rest position during the intake stroke of the engine, a slightly open rest position during the compression and expansion strokes of the engine and the full open position during the exhaust stroke of the engine, and the third condition being a condition wherein the exhaust valve assumes the fully closed rest position during the intake stroke of the engine, a largely open rest position during the compression and expansion strokes of the engine and the full open position during the exhaust stroke of the engine. An actuator is used, which has a hydraulically actuated rod which has first, second and third positions to cause the valve drive mechanism to assume the first, second and third conditions respectively. A hydraulic circuit is used for feeding or drawing a pressurized oil to or from the actuator to move the rod to one of the first, second and third positions.

摘要： A connector for connecting the end of a chemical tube, a blood tube or a tracheal tube inserted to a human body with that of an external circuit. The connector comprises a male terminal part (2) and a conically-connectable female terminal part (3) composed of an inner cylindrical body (5) and an outer cylindrical body (6) which can rotate relative to each other. On the outer surface of the inner cylindrical body (5) and the inner surface of the outer cylindrical body (6), projected lines (11) and grooves (12) which function as engaging means which can stop the rotation inside the connector by contacting with one another due to elastic deformation of the outer cylindrical body are formed. Accordingly, the conically-connectable rotary connector can be detached easily while a rotation mechanism is provided inside the connector.

摘要： A valve lifter of a valve mechanism for an internal combustion engine is provided with a crown-shaped valve lifter body which has a center plate with a recess. A fixing projection is integrally formed with the center plate and is formed along a side wall which defines the recess. An inner shim of a disc shape has a plurality of grooves to which the fixing projection is filled by caulking the fixing projection for fixedly connecting the inner shim with the valve lifter body. Therefore, the inner shim is easily and securely assembled in the recess of the valve lifter body so as not to generate the looseness between the inner shim and the valve lifter body while the assemble performance is improved.

摘要： A valve lifter and processing method therefor include a valve lifter surface to be installed in a recess of a cylinder head of an internal combustion engine. The method includes a grinding step for beveling, or tapering, the circumferential end of a cylindrical wall portion of the valve lifter which slidingly contacts the recess. Excess material resulting from the beveling process is then removed for smoothing the beveled circumferential end. The smoothed surface is then coated with a hardening layer for abrasion protection and smoother operational movement. As a final step, the hardening layer may be polished for further enhancement of operating performance.
