    摘要: A variable displacement compressor includes a supply passage for supplying refrigerant gas from a discharge chamber to a crank chamber and a bleed passage for bleeding the refrigerant gas from the crank chamber to a suction chamber. An oil separator is connected to a drive shaft and is located in the bleed passage. The oil separator rotates together with the drive shaft to centrifugally separate lubricant oil from the refrigerant gas that flows in the bleed passage. An oil chamber is formed in a compressor housing for receiving the separated oil. The pressure in the oil chamber is equal to or greater than the pressure in the crank chamber. The lubricant oil rapidly returns to the crank chamber through a return passage.

    摘要: A variable displacement type swash plate compressor that prevents a drive shaft from moving axially when the difference between a crank chamber pressure and a cylinder bore pressure becomes excessive. A hinge mechanism has a support arm extending from a lug plate and a guide pin extends from a swash plate. The head portion of the guide pin fits in a guide hole formed in the support arm. A cutaway surface is formed in a part of the support arm that defines the guide hole. The cutaway surface forms a clearance in the hinge. The clearance permits the swash plate to move without pulling the drive shaft.

    摘要: A displacement control valve for a variable displacement compressor includes a first valve hole forming a part of a supply passage and a second valve hole forming a part of a discharge passage. Displacement of a reciprocating body is transmitted to each of first and second valve bodies so that each valve body opens or closes the corresponding valve hole. When the reciprocating body is within a predetermined displacement range, a double closing state occurs, in which the first valve body closes the first valve hole and the second valve hole closes the second valve hole. When the reciprocating body is out of the displacement range, a single closing state occurs. Therefore, the control valve prevents the first valve hole from opening concurrently with the second valve hole.

    摘要: A variable displacement compressor has a crank chamber defined in a housing. A drive shaft is arranged in the housing. A piston is accommodated in the cylinder bore. A swash plate is connected to the piston to convert a rotation of the drive shaft. A retainer surface is arranged in the housing and extends substantially perpendicular to the axis of the drive shaft. A restricting mechanism is arranged between the swash plate and the retainer surface. The restricting mechanism receives the swash plate and restricts movement of the swash plate when the inclination of the swash plate decreases.

    摘要: A compressor has a cam plate located in a crank chamber and mounted on a drive shaft and a piston coupled to the cam plate and located in a cylinder bore. The piston compresses gas supplied to the cylinder bore from a separate external circuit by way of a suction chamber and discharges the compressed gas to the external circuit by way of a discharge chamber. The cam plate is tiltable between a maximum inclined angle position and a minimum inclined angle position with respect to a plane perpendicular to an axis of the drive shaft according to a difference between the pressure in the crank chamber and the pressure in the cylinder bore. The piston moves by the stroke based on an inclination of the cam plate to control the displacement of the compressor. A valve is placed between the discharge chamber and the external circuit. The valve selectively connects and disconnects the discharge chamber with the external circuit based on a difference between the pressure acting on the upstream side of the valve and the pressure acting on the downstream side of the valve.

    摘要: A control valve in a variable displacement compressor is disclosed. The compressor adjusts the discharge displacement based on control of the inclination of a swash plate located in a crank chamber. The compressor includes a supply passage for connecting a discharge chamber with the crank chamber to supply the gas from the discharge chamber to the crank chamber and a bleeding passage for connecting the crank chamber with a suction chamber to release the gas from the crank chamber to the suction chamber. The control valve includes a first valve mechanism for selectively opening and closing the supply passage, a second valve mechanism for adjusting the flow rate of the gas released from the crank chamber to the suction chamber through the bleeding passage, and a solenoid mechanism for actuating the first valve mechanism and the second valve mechanism. The first valve mechanism and the second valve mechanism operate independently. The first valve mechanism, the second valve mechanism and the solenoid mechanism are retained in a single housing.

    摘要: A variable displacement compressor for efficiently cooling and lubricating seals arranged on a rotary shaft. The seals are arranged at end portions of the rotary shaft that project from a housing of the compressor. A first lubrication chamber is defined by a first seal in the housing around the front end portion of the rotary shaft. A second lubrication chamber is defined by a second seal in the housing around the rear end portion of the rotary shaft. A shaft passage extends through the rotary shaft to connect the first and second lubrication chambers. Refrigerant gas including lubricating oil flows from a crank chamber to a suction chamber via the first lubrication chamber, the shaft passage, and the second lubrication chamber. This efficiently cools and lubricates the seals.

    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.
