    摘要： A control valve for a variable displacement compressor is provided. A retainer cylinder in the control valve includes a first cylindrical member made of non-magnetic material and a second cylindrical member having a bottom portion made of magnetic material. A shim is intervened a bottom surface of a plunger and inner bottom surface of the second cylindrical member. The retainer cylinder has good magnetic permeability between a coil and the plunger, even though the wall of the cylinder thickens to improve the withstanding pressure to internal refrigerant pressure.

    摘要： A displacement control mechanism used for compressor is installed in a refrigerant circuit. The compressor has a bleed passage and a supply passage. The displacement control mechanism includes a first control valve and a second control valve. The first control valve includes a first valve body and a pressure sensitive member. The first valve body adjusts the opening size of the supply passage. The pressure sensitive member moves in accordance with a pressure in the refrigerant circuit. A pressure detection region is located downstream of the first valve body. The second control valve includes a second valve body. The second valve body adjusts the opening size of the bleed passage. The second valve body moves in accordance with the pressure of the pressure detection region. When the pressure of the pressure detection region increases, the second control valve decreases the opening size of the bleed passage. This permits to start with rapid cooling performance.

    摘要： A scroll type refrigerant compressor having a stationary scroll unit including a spiral member, a movable scroll unit including an orbiting spiral member engaged with the stationary spiral member to define gas-pocket-like variable-volume compression chambers in which the refrigerant gas is compressed in response to a rotation of a drive shaft having an eccentrically arranged drive key member, a drive bushing member having an aperture formed therein in which the drive key of the drive shaft is inserted so as to cause an eccentric motion of the drive bushing member which is operatively engaged with the movable spiral member of the movable scroll unit to thereby drive an orbiting motion of the movable spiral member, and a mechanical space-control unit for suppressing an uncontrolled play of the drive bushing member to thereby move the movable scroll unit in a correct orbiting path with respect to the stationary scroll unit.

    摘要： A scroll type compressor comprising mutually mating stationary and movable scroll members, a drive shaft, a counterweight, a slide key extending from the drive shaft, and a drive bush slidably fit on the slide key. The counterweight is immovably fit on the drive shaft. The slide key has a first axis offset from the longitudinal axis of the drive shaft for causing the movable scroll member to revolve around the longitudinal axis of the drive shaft, and a second axis perpendicular to the first axis. In the second form of the compressor, the counterweight has a guide portion having a first axis offset from the longitudinal axis of the drive shaft for causing the movable scroll member to revolve around the longitudinal axis of the drive shaft, and a second axis. The drive bush is slidably fit on the guide portion. The drive bush is movable along the second axis of the slide key or the guide portion to a smaller extent in one direction by which the eccentricity between the longitudinal axis of the drive shaft and the longitudinal axis of the drive bush is increased, and to a greater extent in the other direction by which the eccentricity is decreased.

    摘要： A scroll type compressor includes a housing defining a discharge pressure region, a fixed scroll member having a fixed base plate and a fixed scroll wall, a movable scroll member having a movable base plate and a movable scroll wall, a fixed wall slidably supporting the movable scroll member, a back pressure chamber defined on a back surface side of the movable base plate. A supply passage connects the back pressure chamber to the discharge pressure region and passes through a sliding portion between the movable scroll member and the fixed wall. A clearance at the sliding portion varies in response to a position of the movable scroll member in a direction in which the movable scroll member approaches to or leaves from the fixed wall, whereby cross-sectional area of the clearance where gas passes is varied to adjust pressure in the back pressure chamber.
