摘要： A displacement control valve included in a variable displacement compressor. The compressor includes a fluid passage for connecting a crank chamber to a discharge chamber. The control valve includes a valve chamber connected to the crank chamber through the fluid passage, a valve hole connected to the discharge chamber through the fluid passage, and a valve body located in the valve chamber. A bellows influences the valve body through a pressure sensitive rod in accordance with suction pressure. A solenoid includes a fixed iron core and a plunger arranged in a plunger chamber. The plunger urges the valve body through a solenoid rod by a force determined by the level of electric current supplied to the solenoid. The fixed iron core, which is located between the valve chamber and the plunger chamber, includes a guide hole for receiving the solenoid rod. An annular passage for connecting the valve chamber to the plunger chamber is formed between the guide hole and the solenoid rod. Accordingly, the pressure of the crank chamber is applied to the plunger chamber through the valve chamber and the annular passage. In this control valve, the valve body has desirable operating characteristics without relying on parts having precise dimensions.

摘要： A variable capacity type compressor includes a swash plate and pistons to effect compressing action. The tilting position of the swash plate is controlled by the pressure in a control pressure chamber into which a coolant in the discharge pressure region is introduced. The pressure in the control pressure chamber is controlled by a capacity control valve mounted to the rear housing in an inclined position relative to a plane perpendicular to the axis of the rotatable drive shaft.

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： In a fitting structure of a control valve in a variable capacity compressor according to the present invention, a step portion 92 is formed by connecting two taper surfaces 93a and 93b, the diameter of each of which decreases progressively towards the depth of a fitting hole 32 (in an inserting direction of a control valve 33) between each step surface portion 57, 67, 74, 91 of a fitting hole 32. A first taper surface 93a at a deep part of each step portion 92 has a smaller inclination in the inserting direction than a second taper surface 93b on the inlet side. The first taper surface 93a is formed so that its inner diameter on the inlet side is a little greater than the outer diameter of each O-ring 61, 70, 77 disposed on each step surface portion 57, 67, 74 in a free condition.
