摘要： A displacement control valve includes a reciprocation body which has a valve body. The reciprocation body includes a first shaft portion that has the valve body and a second shaft portion that is coaxial with the first shaft portion and inserted in a valve hole. The first shaft portion is located adjacent to a solenoid. The second shaft portion is connected to a pressure sensing mechanism. The second shaft portion and the valve hole define a flow path in which refrigerant freely flows. A throttle portion is formed between the first and second shaft portions and coaxial with the first and second shaft portions. Diameter of an end of the throttle portion adjacent to the second shaft portion is set larger than that of the second shaft portion adjacent to the throttle. Flow rate of the refrigerant in the flow path is suppressed by the throttle portion.

摘要： A pressure casing includes a composited cast member. The composited cast member includes an iron-based porous substance whose major component is Fe and which has a large number of pores, and a cast-wrapping member whose major component is a light metal and which cast-wraps a part of the iron-based porous substance at least. The iron-based porous substance includes a connector disposed adjacent to a boundary between the iron-based porous substance and the cast-wrapping member and exhibiting a larger porosity, and a high-strength reinforcer disposed in the iron-based porous substance free from the connector and exhibiting a smaller porosity. The connector is impregnated with the cast-wrapping member, and solidifies therewith, thereby firmly bonding the iron-based porous substance and the cast-wrapping member in the composited cast member. The pressure casing secures strength with the reinforcer, and secures adhesiveness with the connector.

摘要： A variable displacement compressor has a drive shaft, a rotor supported by the drive shaft, a drive plate supported by the drive shaft and a hinge mechanism located between the rotor and the drive plate. The hinge mechanism includes a cam, which is located on the rotor, and a guide portion, which is located on the drive plate. The cam has a cam surface, which has a predetermined profile. One of the cam surface and the guide portion slides against the other in accordance with inclination of the drive plate. The guide portion traces a path corresponding to the profile of the cam surface with respect to the cam. The path includes a first path corresponding to a small displacement region of the compressor and a second path corresponding to a large displacement region of the compressor. The profile of the cam surface is determined such that the first path and the second path bulge in a direction opposite to each other to compensate for fluctuation of a top dead center position of the piston.

摘要： A piston type compressor includes a housing, which defines a crank chamber. A valve plate forms a part of the housing. A drive shaft is located in the crank chamber. A contact member is plastically deformed and press fitted to the drive shaft. An inner wall and a first sub-plate are located in the housing and limit the axial movement of the drive shaft, respectively. After the contact member is attached to the drive shaft, the axial load required to change the position of the contact member is greater than the maximum axial load applied to the drive shaft due to the increase of the pressure in the crank chamber, and less than the load applied to the contact member by the first sub-plate in accordance with the difference in the thermal expansion coefficient of the housing and the drive shaft.

摘要： A variable displacement compressor has a control valve for controlling the displacement of the compressor. When the pressure in a discharge chamber of the compressor (discharge pressure) is equal to or higher than a first threshold value, a controller sets a duty ratio, which is sent to the control valve, to zero % to limit the discharge pressure. As a result, the compressor displacement is minimized and the discharge pressure is lowered. Therefore, the pipes of an external refrigerant circuit does not receive excessive load based on high discharge pressure. When the displacement of the compressor is minimized, circulation of refrigerant in the refrigerant circuit is stopped and refrigerant containing lubricant circulates within the compressor.

摘要： A variable capacity type compressor has a tiltable swash plate and pistons. A control valve is arranged to change the pressure in the crank chamber, to vary the capacity of the compressor by changing the inclination angle of the swash plate by changing the pressure in the crank chamber. The control valve has independently movable first and second plungers and a coil arranged around the first and second plungers so that the coil generates an electromagnetic attraction force acting on and between the first and second plungers. First and second valve elements provided on the first and second plungers can adjust the degree of opening of the first and second fluid passages.

摘要： A variable displacement compressor includes a swash plate and a displacement control valve. The swash plate is moved between a maximum inclination position and a minimum inclination position in accordance with the pressure in a crank chamber. The control valve changes the crank chamber pressure to change the swash plate inclination. The control valve includes a valve body and an electromagnetic actuator for moving the valve body. Movement of the valve body is controlled according to current supplied to the actuator. The control valve also includes a fluid damper for applying fluid resistance to the valve body. The fluid resistance prevents the valve body from moving too quickly. The fluid damper therefore prevents the crank chamber pressure from being suddenly changed. Also, the fluid damper prevents the swash plate inclination from being suddenly changed. Instead of using the fluid damper, the sudden movement of the valve body may be prevented by controlling current supplied to the electromagnetic actuator.

摘要： A drive plate or lug plate is supported on a drive shaft for integral rotation therewith. A cam plate is coupled to the lug plate by a hinge mechanism to integrally rotate with the drive shaft and tilt with respect to the axis of the drive shaft. The cam plate is coupled to a piston to convert the rotation of the drive shaft into linear reciprocating movement of the piston in a cylinder to compress gas supplied from an external circuit and to discharge the compressed gas outward from the cylinder. The hinge mechanism has a first guide pin projecting to the lug plate from the cam plate, a second guide pin projecting to the lug plate from the cam plate in a position following the first guide pin which is the leading pin with respect to the direction of rotation of the drive shalt, a first guide hole formed in a support arm projecting from the lug plate to receive the first guide pin and a second guide hole formed in a second support arm projecting from the drive plate to receive the second guide pin. The first guide hole is located in a position offset from the second guide hole away from the rear surface of the lug plate by a distance which corresponds to the amount of movement of the cam plate and first guide pin caused by compression reaction on the piston during the compression stroke.
