摘要： PROBLEM TO BE SOLVED: To provide good operational responsiveness in the event of sudden braking and provide sufficient outputs.
SOLUTION: Silicone oil 33 is sealed in the recessed part 27a of an output shaft 27 by means of a reaction disc 28. Thus in the event of sudden braking whereby a brake pedal is operated abruptly, the part 28b of the shank of the reaction disc 28 can easily expand more to its front than to its outer peripheral part. Therefore, the amount of opening of an atmospheric pressure valve can be increased and sufficient outputs can be obtained.

摘要： PROBLEM TO BE SOLVED: To prevent lowering of oil resistance of the thin section a diaphragm in a position overlapped with a power piston and to provide a further increased life for a diaphragm than that of a conventional type.
SOLUTION: An annular groove 5a is formed in a position near to the outer peripheral part 5A of a power piston 5. An annular protrusion 6a is formed on a diaphragm 6 and the annular protrusion 6a is engaged with the annular groove 5a. Even when, during operation of a brake boosting device 1, the diaphragm 6 is radially externally pulled, no tensile force is exerted on the thin section of the diaphragm 6 positioned further radially internally than the annular protrusion 6a.

摘要： PROBLEM TO BE SOLVED: To ensure reliable accumulation of a predetermined hydraulic pressure in an emergency accumulator, with suppressing or preventing generation of contact noises. SOLUTION: When an accumulated pressure in an emergency accumulator 9 reaches a predetermined value, a second ball valve 112 opens. Hydraulic fluid in a compartment 101 is throttled by a throttle 81, and discharged to the reservoir at a low flow rate. Accordingly, upward movement of a shoulder piston 70 becomes slower. This makes it difficult for the upper end of the shoulder piston 70 to contact a housing 93 contact less, and thereby generation of contact noises is suppressed. Even if the shoulder piston 70 contacts the housing 93, it does slowly. Therefore, contact noises are barely generated. Since the shoulder piston 70 and the housing 93 contact via an elastic member 80, generation of contact noises can be prevented reliably. Also, when a valve part 98 is mounted onto a valve seat 97, since the valve seat 97 is formed by anelastic member, contact noises are not generated, either.

摘要： PROBLEM TO BE SOLVED: To suppress the generation of pressure fluctuation and noise caused by the vibration of valve constituent parts due to the flow of a fluid passing through a valve part during the operation of a relief valve. SOLUTION: A relief valve 70 for relieving fluid pressure to the tank side when the fluid pressure in a fluid pressure circuit becomes specified pressure has a ball 76 for opening/closing a relief hole 75a of a valve seat, a ball receiver 77 for holding the ball 76, and a compression coil spring 78 for energizing the ball 76 in the direction of closing the relief hole 75a. A passage hole for returning the pressure fluid relieved from the relief hole 75a, to the tank side is opened to the internal wall surface of a valve hole 70a with the ball 76, ball receiver 77 and compression coil spring 78 arranged and built therein. An annular elastic member 90 is fittingly mounted to a part of the ball receiver 77 and the ball receiver 77 is movably held in the valve hole 70a by the elastic member 90. A spring chamber 81 provided with a compression coil spring is formed at one end side of the valve hole 70a, and the spring chamber 81 is connected to the tank side through a throttle passage 92.
