摘要： A piston defines in a cylinder housing a pressure chamber connected to a brake pipe and a fluid supply chamber connected to an oil reservoir. The piston has a recess facing the pressure chamber at one end thereof. A valve member is provided in the recess for making or breaking fluid communication between the pressure chamber and the oil reservoir through the supply chamber. A compression spring is disposed in the recess for urging the valve member into its closed position. A spring retainer is fitted about the end of the piston for holding the spring in the recess. A supporting member is provided in the housing on the opposite side of the pressure chamber from the piston. The valve member is supported by a connecting rod extending axially movably through the spring retainer and the supporting member. A compression spring is connected between the spring retainer and the supporting member for urging the connecting rod in the direction which causes the valve member to open. The spring retainer is movable axially of the piston, while the supporting member is fixed to the housing.

摘要： A relief valve used for hydraulic devices such as the master cylinder for motor vehicles, comprising a housing for passing hydraulic fluid therethrough to adjust the hydraulic pressure, a ball valve disposed in the housing, a coil spring for pushing the ball valve in the housing and plural finger-like portions formed in the inside of the housing to resiliently nip the ball valve so as to prevent the vibration of ball valve in the direction of diameter of the housing at the time of releasing hydraulic fluid through the inside of the housing, thereby making it possible to avoid the generation of strange noise by the vibration of ball valve. It is desirable to form the surface of valve body or the valve body side surface of the finger-like portions so that it has a surface roughness within a specific range in order to make the noise prevention effect more perfect.

摘要： A valve apparatus for prevention of a shocking torque in a clutch mechanism includes a housing having a chamber, the housing including an inlet port for being connected with the master cylinder and an outlet port for being connected with the release cylinder. A valve member is slidably disposed in the chamber to partition the chamber into a first chamber and a second member. The valve member includes a restricted passage connected to the first chamber and the second chamber when the valve member is closed. A first elastic member biases the valve member toward a closed position and a second elastic member biases the valve member in the counter direction of the biassing direction of the first elastic member. A wall member is disposed between the outlet port and the valve member for directing fluid flowing from the outlet port to the valve member. At least one of the first elastic member and the second elastic member is made of a shape memory so that the valve member is biassed by the first elastic member and the second elastic member so as to be opened when the temperature of a fluid flowing into the chamber is under a predetermined value and so that the valve member is biassed by the first elastic member and the second elastic member so as to be closed when the temperature of the fluid flowing into the chamber exceeds a value.

The housing is composed of a cup-shaped shell section having a broad cylindrical outer wall and a flange shaped rear shell section. A bead of the first diaphragm is situated between the inner surface of the front sell section and a securing member of the partition wall for defining the first and second chambers. The second diaphragm has inner and outer beads and through-holes at its periphery. The inner bead is compressed between the peripheral edge of the partition wall and the inner surface of the rear shell section and the outer bead is air-tightly secured between both peripheral edges of the front shell section and rear shell section. The partition wall and the second diaphragm define the third chamber and the second diaphragm and the rear shell section define the fourth chamber. The second and fourth chambers are connected through the cylindrical space formed between the inner surface of the cylindrical outer wall of the front shell section and the outer surface of the partition wall and through-holes of the second diaphragm.

摘要： A fluid pressure servomotor for automotive vehicle brakes embodying a housing provided by assembling two shells, a pressure responsive power wall in the housing, a valve mechanism associated with the power wall and being movable relative thereto to control the differential pressure across the power wall, an actuating member connecting the pedal for manually moving the valve mechanism, and an output member for connecting the power wall to a brake master piston. The shells are assembled by being locked together and can be disassembled and reassembled due to the provision of a mechanism for resiliently restoring a yieldable portion in a locking structure so that the shells are reassembled by a uniting axial movement and a subsequent rotative movement to lock the shells with each other in position against such resiliency.

摘要： A portless-type master cylinder for use in an automotive fluid brake system has a supporting means which resiliently supports the end of a piston adjacent to a push rod so as to preserve a predetermined gap between the end of a valve rod and a stopper member when the master cylinder is not operating. With this arrangement, the wasteful stroke is minimized and the impact at the time of start-up of the master cylinder is reduced.
