摘要： A vane pump includes slits formed in a base portion of a rotary unit rotating in a casing and extend radially from a rotation axis of a rotary unit to be opened outwardly in a radial direction, a vane received in each of the slits to be protruded from or retreated into the slit, an annular chamber formed around the base portion in the casing and pump rooms formed by defining the annular chamber by using the vanes. The vane pump is operated to discharge fluid sucked into an associated pump room by rotating the rotary unit and thereby periodically increasing or reducing volume of the pump rooms. The vane pump further includes a fluid force generating portion provided on at least one of the rotary unit and the casing to generate fluid force to the upper side in an axial direction of the rotation axis by rotation of the rotary unit.

摘要： This invention provides a chain tensioner that is compact, excellent in operation, easy to maintain and handle and low in manufacturing cost. This chain tensioner has a tubular housing 1 having a bottom, a plunger 3 installed in the inner periphery 1a of the housing so as to smoothly slide inside the housing, a return spring 5 providing the plunger 3 with a force pushing outward, a plurality of latching grooves 33a–33d formed on the outer periphery of the plunger 3, a resister ring 7 capable of locking in the latching grooves, and a check valve 6 that is mounted on the bottom of the housing inner periphery 1a, provides the housing inner periphery 1a with operating oil and prevents its reverse flow. The range of backward movement of the plunger 3 is limited by mating the resister ring 7 locked in the latching grooves 33a–33d with a first stopper 21 formed on the housing inner periphery 1a.

摘要： In a tube for a heat exchanger, a plurality of passages is defined. The passages are arranged in rows parallel to a major axis of the tube cross-section and staggered. When the tube is extruded, an extrusion material can flow around dies for forming passages and easily merge between the dies. Since walls between adjacent passages can be easily formed, formability of the tube is improved.

摘要： A lash adjuster in a valve actuator includes a lifter body having an end plate having its top surface in contact with a cam and formed with a threaded hole in its bottom surface. An adjuster screw is inserted in the threaded hole with its external thread in engagement with the internal thread of the threaded hole. An elastic member is mounted in the threaded hole over the adjuster screw to bias the adjuster screw axially downward. Both of the threads have a sawtooth-shaped section with its pressure flank having a greater flank angle than its clearance flank. One of the pressure flanks is formed with a satin-finished rugged surface which is covered by a hard film which is non-reactive with a low-friction oil. With this arrangement, even after the threads have become worn, the friction coefficient between the thread surfaces is kept substantially constant.

摘要： An installation structure allows easy installation of vibration-proofing members in an electric motor, which avoid resonance due to vibration of an engine, without increasing the number of components. A bottom wall of an installation hole for receiving the electric motor is spaced from a bottom wall of a yoke. Also, flexible tabs are formed on the bottom wall of the yoke. In this arrangement, the electric motor is installed in the installation hole in a manner such that the flexible tabs are pressed into contact with a step portion arranged on the bottom wall of the installation hole.

摘要： A valve lifter includes a guide cap mounted between a cam and the top end of a valve stem and which is slidably supported so as to be capable of moving in the axial direction. The guide cap has an end wall formed with a threaded through-hole. An adjusting bolt is threadedly engaged in the threaded hole. The adjusting bolt is biased toward the valve stem by a spring. The threaded hole and the adjusting bolt have serration-shaped threads so that the adjusting bolt can be moved toward the valve stem under the force of the spring. Since the adjusting bolt is threaded into the threaded hole formed in the guided cap, the axial length of the valve lifter is short.

摘要： A direct valve drive device which can open and lose a valve with accuracy even if a negative valve clearance forms between the cam and the valve stem due to a difference in thermal expansion coefficient between the cylinder head made of aluminum alloy and the iron valve. A valve lifter is mounted between the cam and the valve stem being biased toward the cam by a valve spring. An adjuster bolt is threaded into a threaded hole formed in the valve lifter. The force of a spring is applied to the adjuster bolt so that the adjuster bolt move, while rotating, toward the valve stem. Formed between the threadedly engaging portions of the adjuster bolt and the threaded hole is an axial hole which is smaller than the height of a ramp formed on the cam but large enough to absorb any difference in thermal expansion between the cylinder head and the valve. Even if the valve clearance changes toward the negative side, the axial gap absorbs such a change, thus preventing the valve from being pushed by the base circle of the cam.
摘要翻译：即使由于铝合金气缸盖与铁阀之间的热膨胀系数不同，即使在凸轮和阀杆之间形成负阀间隙也能够精确地打开和断开阀的直接阀驱动装置。气门挺杆安装在凸轮和阀杆之间，阀门通过阀弹簧朝向凸轮偏压。调节螺栓拧入形成在阀提升器中的螺纹孔中。弹簧的力被施加到调节螺栓上，使得调节螺栓在旋转的同时朝向阀杆移动。形成在调节螺栓的螺纹接合部分和螺纹孔之间的轴向孔小于形成在凸轮上的斜面的高度，但足够大以吸收气缸盖和阀之间的热膨胀差异。即使阀间隙向负侧变化，轴向间隙吸收这种变化，因此防止阀被凸轮的基圆圈推动。

摘要： An inside wall surface of a cap covering the end portion of a header tank is formed into a spherical shape, and a connecting portion between the inside wall surface of the cap and a inside wall surface of a tank portion is separated away from a connecting portion between the inside wall surface of the tank portion and an outside wall surface of a tube. Thus, the brazing material is suctioned into both connecting portions (both gaps) sufficiently, and both connecting portions are brazed firmly.
