摘要： A piston seal is provided in a circumferential groove formed in a cylinder body. The piston seal is capable of sealing a pressure chamber, which supplies fluid pressure to a discharge passage, from a supply passage, which communicates with a reservoir. The piston seal comprises: an annular base portion; an inner circumferential lip portion projecting from an inner circumferential side of the base portion and being in slidable contact with an outer circumferential surface of a piston; an outer circumferential lip portion projecting from an outer circumferential side of the base portion and being in abutment with the circumferential groove of the cylinder body; and an intermediate projecting portion which is formed between the inner circumferential lip portion and the outer circumferential lip portion of the base portion and which is projected beyond the outer circumferential lip portion. Cutout grooves are formed on a tip side of the intermediate projecting portion. Therefore, when releasing air, a sufficient amount of brake fluid can be supplied through a gap between the piston seal and a bottom surface of the circumferential groove, and the cutout groove. As a result, the number of repetitions of an air releasing operation can be minimized.

摘要： A large-diameter bore portion is formed in a portion defining a pressure chamber in a cylinder body on a side opposite to a circumferential groove relative to a slidable inner-diameter portion. A communication groove capable of allowing communication between the circumferential groove and the large-diameter bore portion is formed in an upper portion of the slidable inner-diameter portion. A point of maximum depth of the communication groove is located radially outward of a bottom of the circumferential groove. The master cylinder of the present invention is capable of preventing the supply of a brake fluid from being restricted in an evacuation process, and enables a reduction in length to be machined of the communication groove, thus reducing the time for machining and suppressing an increase in cost.

摘要： A master cylinder has a cylinder member in the shape of a cylinder, one end of which is closed, and a piston inserted in the cylinder member to form a pressure chamber in the cylinder member. The cylinder member is formed with a port for providing communication between the pressure chamber and a reservoir. The port is formed during casting of the cylinder member, thereby eliminating the need to form the port by boring, and forming the port into an elongated-hole shaped sectional configuration.

摘要： A master cylinder comprises a cylinder body in a cylindrical form having one end closed and including a discharge passage and a supply passage for a brake fluid, the supply passage being communicated with a reservoir. A piston is slidably disposed in the cylinder body, so as to form a pressure chamber for supplying a fluid pressure to the discharge passage. A piston seal is provided in a circumferential groove formed in the cylinder body, which has an inner circumferential surface thereof in slidable contact with the piston and is capable of sealingly disconnecting the supply passage and the pressure chamber. The cylinder body includes a communication groove which opens into the circumferential groove and extends from the circumferential groove toward the closed end of the cylinder body to thereby connect the circumferential groove and the discharge passage. The communication groove is formed outwardly beyond a bottom surface of the circumferential groove relative to a radial direction of the cylinder body.

摘要： A pneumatic booster has a valve member arranged to operate stably even under a large differential pressure. The inside of a housing is divided into a constant-pressure chamber and a variable-pressure chamber by a diaphragm. A plunger and a valve member are disposed in a valve body supported by the diaphragm such that the plunger and the valve member are slidable relative to each other. The valve member is formed from a rigid reinforcing member and an elastic member bonded to the reinforcing member. The plunger is movable in association with an input shaft. The movement of the plunger is transmitted to the valve member through a valve spring, causing the valve member to separate from a seat portion provided on the plunger. Thus, compressed air is introduced into the variable-pressure chamber from a pneumatic device through passages to produce a differential pressure between the variable-pressure chamber and the constant-pressure chamber, which is supplied with a negative pressure from an engine, thereby driving the valve body.
摘要翻译：气动助力器具有阀构件，其布置成即使在较大压差下也能稳定地运行。壳体的内部通过隔膜被分为恒压室和可变压力室。柱塞和阀构件设置在由隔膜支撑的阀体中，使得柱塞和阀构件相对于彼此可滑动。阀构件由刚性加强构件和结合到加强构件的弹性构件形成。柱塞可与输入轴相关联。柱塞的移动通过阀弹簧传递到阀构件，使得阀构件与设置在柱塞上的座部分离。因此，压缩空气从气动装置通过通道被引入到可变压力室中，以产生可变压力室和恒压室之间的压力差，该压力腔被供给来自发动机的负压，从而驱动阀体。
