摘要： A fluid pressure operated electrical switch has a piston element subject to an operating fluid pressure on its acting end face for actuating an electrical switch. The switch employs a limiting member for limiting motion of the piston element to a predetermined extent in order to prevent the switch from being damaged due to overstroke of the piston element. The limiting member includes a flange at the rearmost end of the piston element and an annular shoulder in a bushing which is closely fitted within a port of a switch body for the operating fluid pressure. The piston element is loosely fit in the bushing with the flange in engagement within the shoulder of the bushing such that the flange and shoulder cooperate to provide limitation of the stroke of the piston element.

摘要： A hydraulic system in which pressurized fluid fed from a hydraulic pump is distributed through a distributor valve, on one part to a hydraulic booster for a brake and on the other part to a power steering unit or other hydraulic device. The distributor valve has a spool valve slidably fitted in a casing, the spool being displaced according to a fluid pressure differential acting at opposite ends thereof to increase the discharge pressure of the hydraulic pump in response to an increase in the fluid pressure at a first outlet port of the casing leading to the hydraulic booster or in the fluid pressure at a second outlet port leading to the power steering unit. Upon application of brake, a fluid passage which drains the first outlet port through a power piston is closed by movement of an input piston which is associated with a brake pedal, thereby slidingly displacing a valve piston. At this time, the discharge pressure of the hydraulic pump is increased and a third outlet port of the distributor valve is opened to admit the pressurized fluid from the hydraulic pump into a pressure chamber of the power piston through a valve which is opened by the displacement of the input piston for applying brake. An accumulator which is connected to the third outlet port of the distributor valve stores the pressurized fluid when the discharge pressure of the hydraulic pump is high, supplying the stored fluid to the pressure chamber of the power piston in the event of trouble with the pump or when a valve for the pressure chamber is opened.

摘要： A hydraulic power booster system having a power piston which may be adapted to be connected with an input member of a brake master cylinder and which is actuated when hydraulic pressure fluid is introduced into a power pressure chamber defined at one side of the power piston. An orifice is disposed between a hydraulic pressure source and hydraulic pressure reservoir with an opening that is restrictable for establishing a hydraulic pressure drop thereacross when a brake pedal is actuated. A control valve introduces the hydraulic pressure fluid from the pressure source to the power pressure chamber in response to a pilot hydraulic pressure established in a pilot chamber defined by the control valve upstream of the orifice. The flow of controlled hydraulic fluid through the pilot chamber becomes restricted for establishing the pilot hydraulic pressure therein when the brake pedal is actuated for restricting the opening of the orifice and thus establishing a hydraulic pressure drop thereacross.
