摘要： In a structure for mounting a filter in a compressor, a mounting member is connected to the filter. A receiving hole is formed in a housing of the compressor for receiving therein the mounting member. A first fitting portion is formed on an inner circumferential surface of a holding portion of the filter. A second fitting portion is formed on an outer circumferential surface of the mounting member for having fitting relation to the first fitting portion for an overlap distance in a radial direction of the receiving hole. When the mounting member is received in the receiving hole with the fitting relation, the filter is disposed in a fluid passage of the housing. A clearance having a dimension is formed between an outer circumferential surface of the holding portion and an inner circumferential surface of the receiving hole. Minimum value of the dimension is smaller than the overlap distance.

摘要： A displacement control valve for a variable displacement compressor includes a first valve hole (36) forming a part of a supply passage and a second valve hole (37) forming a part of a discharge passage. Displacement of a reciprocating body is transmitted to each of first (39) and second (40) 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 (36) and the second valve hole closes the second valve hole (37). When the reciprocating body is out of the displacement range, a single closing state occurs. Therefore, the control valve prevents the first valve hole (36) from opening concurrently with the second valve hole (37).

摘要： A control valve includes a separation portion, which is part of a rod, blocks a through hole that connects a valve chamber and a second chamber with each other. Therefore, the pressure of the second chamber is not directly affected by changes in the opening degree of the control valve. The second chamber and a valve hole forming a part of the through hole are both connected to a second pressure zone through an upstream section of a supply passage. This prevents creation of pressure difference between the valve hole and the second chamber, and thus prevents entry of foreign particles in sliding portions between the through hole and the rod.

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.

摘要： In a control system of a variable displacement compressor, a pressure sensing means mechanically detects at least one pressure in the refrigerant circuit. A varying means varies a reference value for positioning a valve body. A pressure detector electrically detects the pressure detected by the pressure sensing means in the refrigerant circuit and/or physical quantity which correlates with the detected pressure. A calculator calculates a maximum value of urging force applied to the valve body by the varying means toward an increasing side of the displacement of the compressor. The urging force applied to the valve body is controlled not to exceed the maximum value toward the increasing side of the displacement. The displacement of the compressor is maximized by the pressure sensing means under the pressure for calculating the maximum value when the varying means applies urging force of the maximum value to the valve body.

摘要： A control valve (CV) is used for a variable displacement compressor installed in a refrigerant circuit of a vehicle air conditioner. The control valve (CV) has a valve housing (45). A valve chamber (46) is defined in the valve housing (45). A valve body (43) is accommodated in the valve chamber (46). A pressure sensing chamber (48) is defined in the valve housing (45). A pressure sensing member (54) separates the pressure sensing chamber (48) into a first pressure chamber (55) and a second pressure chamber (56). The pressure at a first location in the refrigerant circuit is applied to the first pressure chamber (55). The pressure at a second location in the refrigerant circuit, which is downstream of the first location, is applied to the second pressure chamber (56). The pressure sensing member (54) moves the valve body (43) in accordance with the pressure difference between the first pressure chamber (55) and the second pressure chamber (56) such that the displacement of the compressor is varied to counter changes of the pressure difference. At least one of the first pressure chamber (55) and the second pressure chamber (56) forms a part of the refrigerant circuit.
