    摘要: A rotary compressor includes a cylindrical-shaped housing, a rotor rotatably mounted in the housing and formed with diametrically extending slits, and a pair of movable vanes each slidably disposed in each of the slits with its opposite ends extending beyond the associated slit in abutting relation to the inner surface of the housing. The clearances between the movable vanes and the slits of the rotor are made larger about the central portion of the rotor than adjacent to the outer periphery thereof by making each of the vanes thinner about its central portion than at its opposite end portions or making each of the slits wider about the central portion of the rotor than adjacent to the outer periphery of the rotor. With the arrangement, shearing stresses caused by shearing of oil in the compressor can be suppressed to thereby reduce a loss in the torque of the compressor, and the maximum stress on the movable vanes can be limited below an allowable stress to improve the anti-breakage characteristics of the vanes.

    摘要: A compressor bypass passage has an inlet portion and an outlet portion which is connected to the suction passage. The inlet portion of the bypass passage has an opening which is able to be open to the compression chamber when the compression chamber is in a decreasing volume stroke, thereby to spill the refrigerant from the compression chamber into the suction passage. A control pressure chamber is formed in the housing. A valve member is arranged in the inlet portion of the bypass passage. The valve member is actuated in response to a variety of pressures of the refrigerant in the control pressure chamber for adjusting the area of the opening of the inlet portion of the bypass passage. A pressure supply passage for supplying a refrigerant, which pressure is higher than the pressure in the suction passage, is connected to the control pressure chamber. A spill passage for spilling a part of the refrigerant interconnects the control pressure chamber to the suction passage. A pressure control valve is arranged in the pressure supply passage or in the spill passage for controlling the pressure in the control pressure chamber.

    摘要: A rotary compressor formed with an unloading port maintaining a working space in communication with a suction chamber and opened and closed by a valve, to vary the capacity of the compressor. The internal pressure of the working space is sensed in a compression stroke or this pressure and the pressure of a fluid drawn by suction are both sensed, so as to open and close the valve based on the sensed internal pressure of the working space or the pressure differential between the internal pressure of the working space and the pressure of the fluid drawn by suction, to give suitable hysteresis to the operation characteristics of the on-off valve to stabilize the operation of the on-off valve.

In its simplest form, the modulator comprises a body in which are formed a main hydraulic passage adapted to connect the master cylinder to a wheel cylinder, and a pressure relief passage for relieving the pressure in the wheel cylinder. The main passage is opened and closed by a normally open shutoff valve operated by a piezoelectric actuator, and the relief passage is controlled by a normally closed shutoff valve operated by an associated piezoelectric actuator. Adjusting mechanisms are provided to adjust the axial position of the piezoelectric elements of the actuators in such a manner that the valve clearance of the shutoff valves is adjusted to an optimal amount.

    摘要: A wheel cylinder and brake piston are formed in the brake caliper of each wheel of a vehicle. A piezoelectric device, which is formed of laminated piezoelectric elements, is formed in the brake caliper such that it is connected with the wheel cylinder. By applying a voltage to the piezoelectric elements the piston device is made to expand and contract to thereby vary the volume of the wheel cylinder. Brake fluid is supplied from the master cylinder to the wheel cylinder via fluid passage formed in the brake caliper and a control valve for opening and closing this passage is formed in the passage. When there is a high pressure in the wheel cylinder, the piezoelectric device expands and the control valve closes. Then, by lowering the voltage the piezoelectric device contracts and the pressure in the wheel cylinder decreases.
