    • A fluid-filled type vibration-damping device having a movable rubber plate housed within a partition member partitioning a pressure-receiving chamber and an equilibrium chamber from each other. The movable rubber plate is moved owing to the pressure difference between the two chambers. The movable rubber plate comprises the movable rubber plate formed of a generally disk shaped rubber elastic body having formed thereon in alternating fashion concave grooves and convex ribs each extending in a circumferential direction about a same center axis, the convex ribs have tapered cross section gradually narrowing in width towards an distal end thereof, and the concave grooves and convex ribs are disposed at the same locations in a diametrical direction on either face of the movable rubber plate so that the thickness of the movable rubber plate is varied in the circumferential direction.
    • 一种流体填充式减震装置,其具有容纳在分隔部件内的活动橡胶板,所述分隔部件将压力接收室和平衡室分隔开。 活动橡胶板由于两个腔室之间的压差而移动。 活动橡胶板包括由大致圆盘状的橡胶弹性体形成的可动橡胶板,该橡胶弹性体在其上形成有交替的凹槽和凸肋,每个圆周方向围绕相同的中心轴线延伸,凸肋具有逐渐变细的锥形 并且凹槽和凸肋在可动橡胶板的任一面上沿直径方向设置在相同位置处,使得可动橡胶板的厚度在圆周方向上变化。

    • A control valve includes an accommodation cylinder, a coil, a stator, a plunger, and a valve body. Electromagnetic force is generated between the stator and the plunger and the plunger moves relative to the stator. The valve body adjusts the opening degree of a valve hole. A flat surface and a peripheral wall are formed in an end of the stator. The peripheral wall has a tapered cross-section with an inclined inner surface. The inclined inner surface and the flat surface define a recess. The plunger has a frustum portion. The frustum portion includes a flat distal surface and an annular inclined surface. The taper angle of the peripheral wall is equal to or less than twenty degrees. The diameter of the flat distal surface of the frustum portion is equal to or greater than eighty percent of the largest diameter of the annular inclined surface.

    • A piston compressor having cylinder blocks, each defining cylinder bores in which a piston is axially reciprocally arranged. Front and rear housings are connected to the cylinder blocks via valve port plates, so that compression chambers are formed between the valve port plates and the cylinder blocks and inlet and outlet chambers are formed between the valve port plates. The valve port plates form inlet and outlet ports for each of the compression chambers and inlet valves and outlet valves formed as thin resilient web members are provided for the inlet and outlet ports, respectively, to control the feeding and discharge of the gas, respectively. The valve port plates having, on the surfaces thereof facing the outlet valve around the inlet ports, a roughened area having a surface roughness value R.sub.z of between 10 to 25 .mu.m and an average spacing value L of between to 50 to 100 .mu.m.

    • A fluid filled type vibration damping device having a pressure-receiving chamber and an equilibrium chamber disposed on either side of a partition member. A movable cover member juxtaposed against the partition member from the pressure receiving chamber side to cover a communicating hole of the partition member. An outside peripheral edge of the movable cover member is held in intimate contact against the partition member through urging force of an elastic retainer portion. Pressure of both chambers will acts on both faces of a movable rubber film, thereby constituting a pressure fluctuation absorbing mechanism. The outside peripheral edge of the movable cover member is separated from the partition member in opposition to the urging force by negative pressure in the pressure receiving chamber for providing a shunting mechanism for preventing excessive negative pressure in the pressure receiving chamber.
    • 一种流体填充型减震装置,具有设置在分隔构件的任一侧的受压室和平衡室。 可动盖部件从压力接收室侧并排配置在分隔部件上,以覆盖分隔部件的连通孔。 通过弹性保持器部分的推动力,可动盖部件的外周边缘保持与分隔部件的紧密接触。 两个室的压力将作用在可移动橡胶膜的两个面上,从而构成压力波动吸收机构。 可动盖构件的外周边缘与压力接收室中的压力相反的压力与分隔构件分离,用于提供用于防止压力接收室中的过大负压的分流机构。
