    摘要: A rolling piston type compressor of a simplified design having a single rolling piston, capable of reducing a variation in torque. The compressor has a housing in which a rolling piston 42 is arranged so that an orbital movement of the rolling piston is obtained about the axis of a crankshaft 5, so that a first operating chamber 40 is formed between the rolling piston 42 and the housing. A cylindrical pillar 47 which is stationary is arranged in the rolling piston, so that a second operating chamber is formed between the rolling piston and the pillar. The medium compressed in the first operating chamber is introduced into the second operating chamber for obtaining two step compression.

    摘要: A rotary compressor including two rotary disc-shaped members having a diameter slightly smaller than that of a rotor each disposed on opposite ends of the rotor and supported on the same rotary shaft as the rotor for rotation, and two disc-shaped recesses each formed on one of inner opposite end surfaces of a housing for receiving therein one of the plurality of rotary disc-shaped members. A small gap is formed between the inner end surfaces of the housing and the end surfaces of the rotor, and small gaps are formed between surfaces of the rotary disc-shaped members and surfaces of the disc-shaped recesses. The area through which a fluid leaks from the high pressure side to the low pressure side in the housing is minimized, and resistance is offered by the tortuous path to the flow of the fluid toward the rotary shaft, to thereby minimize the leakage of fluid during operation of the compressor.

    摘要: A scroll type compressor having movable and fixed scrolls forming a working chamber with a movable scroll supporting arrangement to prevent tilting of the movable scroll into the fixed scroll thereby making it possible to extend the axial length of the scrolls. A main supporting plate is fixed on a housing between two other supporting plates which are spacedly fixed on the movable scroll, or vice versa. The other supporting plates press on the main supporting plate from both sides via ball bearings. When the movable scroll is about to tilt, the supporting plate arrangement prevents the movable scroll from tilting.

    摘要: Antiskid hydraulic braking system comprising a first shutoff valve operable to shutoff hydraulic pressure from a master cylinder to wheel cylinder as the brakes tend to lock the wheels of a vehicle. Wheel cylinders are connected to a reservoir through a second shutoff valve which relieves hydraulic pressure at the wheel cylinders until the tendency toward wheel lock disappears. The system further comprises an intermittently operable high speed hydraulic pump, such as a piezoelectric pump, which serves to pump the brake fluid in the reservoir to the wheel cylinders to restore hydraulic pressure in the wheel cylinders. The piezoelectric pump comprises a pump plunger having a small diameter head defining a pumping chamber and a large diameter base defining a delivery or pressure chamber. The brake fluid under pressure in the delivery chamber acts upon the plunger base to hydraulically preload the piezoelectric elements.

    摘要: Hydraulic fluid supply system for supplying high pressure hydraulic fluid to power actuators for power steering systems includes a pumping mechanism having independent pumping chambers adapted to discharge fluid to a supply line leading to the power actuator. The supply line contains a variable orifice and a flow control valve responsive to the pressure difference generated by the variable orifice. The pumping chambers include at least first and second pumping chambers connected to first and second feed lines. A switching valve operatively interconnected to the variable orifice and actuated by an electrically operable drive mechanism selectively connects the second feed line to the supply line or to the first feed line. When the drive mechanism shifts the switching valve so that the second feed line leading to the second pumping chamber is switched from the first feed line to communicate with the supply line, a part of the high pressure fluid flowing through the fluid line is returned to the second pumping chamber by bypassing the power actuator thereby disabling the second pumping chamber and reducing the flow rate of the fluid flowing to the power actuator. Disablement of the second pumping chamber during "drooping" reduces the effective overall displacement capacity of the pumping mechanism thereby saving a considerable amount of power. The system may be electronically controlled depending on various operational conditions of the vehicle and the like.

    摘要: A rotary compressor including a housing having therethrough a cylindrical bore, end plates attached to the housing to close the open axial ends of the bore respectively, an eccentric rotor rotatable in the bore and vanes slidably mounted in the rotor. A working chamber defined between the adjacent pair of vanes communicates with a discharge chamber outside of the housing through a discharge opening in the wall of the housing. First and second passages have their respective one ends opening to the cylindrical bore and the respective other ends communicating with the discharge chamber. The one end of the first passage is positioned at a location or adjacent thereto where the leading one of the adjacent pair of vanes is positioned when the working chamber defined therebetween has its volume starting to decrease. The one end of the second passage is positioned at a location where the one end of the second passage together with the discharge opening is opened to one of the discharge chambers with the latter having its volume decreased and communicating with the discharge opening. First and second check valves respectively in the passages are opened only when the working chambers respectively associated with the passages have therein pressures higher than respective predetermined values.
