摘要： In a hydraulic pressure control valve for use with a brake master cylinder, a hollow body of one-piece structure has an internal stepped bore through which outlet and inlet bores formed respectively in one and other ends of the body communicate with each other. A mounting portion to the master cylinder is provided adjacent the other end of the body. A piston is arranged in the stepped bore for reciprocative movement therealong in response to hydraulic pressure from the master cylinder. One end of the piston remote from the outlet bore has an end face serving as a valve seat. A substantially tubular cap element is arranged in the inlet bore and supports the one end of the piston. The cap element is fixed to the body by fixing arrangement which is accompanied with no relative rotation between the cap element and the body. A valve element arranged in a valve chamber defined by the cap element is normally spaced away from the valve seat, but is seated thereon when the hydraulic pressure reaches a predetermined level to move the piston toward the valve element.

摘要： A pump apparatus includes a plunger, an eccentric cam for moving the plunger toward a pressure chamber, a drive shaft supporting the eccentric cam, and an output shaft of a motor for imparting a rotational force to the drive shaft. A convex portion is formed on one end of one of the drive shaft and the output shaft whereas a concave portion is formed in one end of the other of the two shafts. The convex portion is fitted in the concave portion to interconnect the drive shaft and the output shaft. The convex portion is fitted in the concave portion with a clearance therebetween. A holder member for always holding the convex portion and the concave portion in engagement with each other in the direction of rotation of the drive shaft is provided at an area of fitting between the convex portion and the concave portion. With this arrangement, noises resulting from the impingement of one of the convex portion and the concave portion upon the other during the operation of the pump apparatus are eliminated.

摘要： This invention not only positively reduces the vibrations and noises due to pulsation pressure generated by a hydraulic pressure pump 10, but also effectively prevents the generation of foreign sounds that may occur when a liquid-operated booster 90 is abruptly activated. For this purpose, a throttle valve unit 80 (180, 280) for greatly reducing the flow area until the pressure differential or flow rate reaches a predetermined value is provided between an accumulator 70 for accumulating pressurized liquid and the liquid-operated booster 90 which utilizes the pressurized liquid as an operation source. When the pressure accumulated within the accumulator 70 is at a predetermined value or less, the throttling function of the throttle valve unit 80 (180, 280) is cancelled.

摘要： A plastic piston of master cylinder has a first member having a small diameter portion and a second member having a large bore portion. Excess welding resin is prevented from being leaked into a seal ring mounting groove formed on a part of the outer peripheral surface of the small diameter portion by provision of welding portions in the form of a space defined between an outer peripheral surface of the small diameter portion of the first member and the large bore portion of the second member, and a gap defined between a tip end of the small diameter portion of the first member and the bottom of the large bore portion, the space and gap being provided respectively for preventing the excess welding resin from being leaked into the seal ring mounting groove. The plastic piston has no parting lines along the seal ring mounting groove which results in achieving a superior seal effect.
