    摘要: A variable displacement compressor includes a bleed passage for releasing gas from a crank chamber to a suction chamber and a supply passage for supplying gas from a discharge chamber to the crank chamber. A control valve includes an outlet valve mechanism located in the bleed passage and an inlet valve mechanism located in the supply passage. When the inlet valve mechanism is in the open state, the outlet valve mechanism is in the closed state. An outlet valve body of the outlet valve mechanism has a communication passage. When the outlet valve mechanism is in the closed state, the communication passage is opened to communicate the crank chamber with the suction chamber. Therefore, when the compressor is operating at the minimum displacement, a gas circuit is positively formed within the compressor, and atomized lubricant in refrigerant gas positively lubricates the moving parts of the compressor.

    摘要: A control valve used for a variable displacement compressor comprises a valve housing, a valve chamber defined in the valve housing, a valve body. The valve body is located in the valve chamber. A pressure sensing chamber is defined in the valve housing. A movable wall is located in the sensing chamber to divide a first pressure chamber and a second pressure chamber. The movable wall moves in accordance with the pressure difference between the first pressure chamber and the second pressure chamber. A rod transmits the movement of the movable wall to the valve body. The pressure directed in the vicinity of the end portion of the rod is the same type pressure directed in the first pressure chamber or in the second pressure chamber. An actuator determines the target pressure difference between the two pressure chambers. This permits the displacement of the compressor to be quickly changed.

    摘要: The present invention discloses a method for installing pistons in cylinder bores formed in a cylinder block of a compressor. The piston on one end of the cylinder block and a positioning jig on the other end of the cylinder block are arranged. The positioning jig is inserted into the cylinder bore such that part of the positioning jig protrudes from the cylinder bores toward the piston. The protruding part of the positioning jig is engaged with the piston to determine the position of the piston. The piston is inserted into the cylinder bore while maintaining the engagement between the jig and the piston. The positioning jig is removed from the cylinder bore. This facilitate automation of installation of pistons in cylinder bores.

    摘要: variable displacement compressor has a drive shaft extending through a crank chamber. A lug plate is integrally fixed to the drive shaft. A drive plate is connected to and driven by the lug plate by a hinge mechanism. The drive plate inclines with respect to the drive shaft to vary the displacement of the compressor. The hinge mechanism has a linear guide on the lug plate and a pin projecting from the drive plate toward the lug plate. A bearing surface engages the pin. The pin has an axis that intersects an axis of the guide. The axis of the pin is parallel to the axis of the drive shaft when the compressor operates with a maximum load.

    摘要: A swash plate 20 made of an aluminum-based material is allowed to be inclined in the axial direction of a rotary shaft 18 and to rotate integrally with the rotary shaft 18 due to the engagement between guide holes 251 formed in the support arms 25 made of an iron-based material and heads 231 of to-be-guided pins 23 made of an iron-based material. The inclination of the swash plate 20 is guided based upon a slide guide relationship between the guide holes 251 and the to-be-guided pins 23 and upon a slide support action of the rotary shaft 18. The inclination-limiting protuberances 191 integrally formed on the rotary support member 19 made of the iron-based material come into contact with the to-be-guided pins 23. The swash plate 20 is inclined at a maximum angle in a state where the inclination-limiting protuberances 191 come into contact with the to-be-guided pins 23.

    摘要: A first bleed passage and a second bleed passage each connect a crank chamber of a compressor with a suction chamber of the compressor. A first supply passage and a second supply passage each connect the crank chamber with a discharge chamber of the compressor. A first control valve adjusts the opening size of the first supply passage in response to the pressure in the suction chamber. A second control valve includes a ball valve and an electromagnetic actuator. The ball valve adjusts the opening size of the second supply passage and the opening size of the first bleed passage. The electromagnetic actuator moves the ball valve. The ball valve is moved to a first position and to a second position. At the first position, the ball valve closes the second supply passage and opens the first bleed passage. At the second position, the ball valve opens the second supply passage and closes the first bleed passage. A displacement control device, which includes the first and second control valves, readily and reliably changes the displacement of the compressor.
