摘要： A control valve is located in a variable displacement compressor that is installed in a refrigerant circuit. The control valve operates such that the pressure difference between first and second pressure monitoring points in the refrigerant circuit seeks a predetermined target value. The first pressure monitoring point is located in a discharge chamber of the compressor. The second pressure monitoring point is located in a flow pipe that extends from the discharge chamber. The static pressure of refrigerant in the discharge chamber is introduced into a control valve from the first pressure monitoring point. A pressure that includes the static pressure and the dynamic pressure of refrigerant in the flow pipe is introduced into the control valve from the second pressure monitoring point. As a result, the displacement of the compressor is reliably controlled without being affected by the thermal load of an evaporator.

摘要： A displacement control mechanism used for compressor is installed in a refrigerant circuit. The compressor has a bleed passage and a supply passage. The displacement control mechanism includes a first control valve and a second control valve. The first control valve includes a first valve body and a pressure sensitive member. The first valve body adjusts the opening size of the supply passage. The pressure sensitive member moves in accordance with a pressure in the refrigerant circuit. A pressure detection region is located downstream of the first valve body. The second control valve includes a second valve body. The second valve body adjusts the opening size of the bleed passage. The second valve body moves in accordance with the pressure of the pressure detection region. When the pressure of the pressure detection region increases, the second control valve decreases the opening size of the bleed passage. This permits to start with rapid cooling performance.

A control device may be disposed within the unit housing and the control device preferably controls electric components of the compressor. Further, a suction passage is preferably defined to introduce the fluid into the compression chamber. The suction passage preferably penetrates through the unit housing so as to directly cool the control device due to the fluid flowing through the suction passage.

摘要： A control valve is located in a variable displacement compressor incorporated in a refrigerant circuit. The control valve controls the displacement of the compressor in accordance with a pressure difference between a first pressure monitoring point and a second pressure monitoring point, which are located in the refrigerant circuit, such that the pressure difference seeks a predetermined target value. An adjusting valve, which is a variable throttle valve, is located in a section of the refrigerant circuit between the first and second pressure monitoring points. The adjusting valve adjusts the restriction amount of the refrigerant in relation to the refrigerant flow in the refrigerant circuit. The compressor displacement is thus optimally controlled.

摘要： A vehicle air conditioning apparatus includes a refrigerant circuit. The air conditioning apparatus is driven by an engine. The air conditioning apparatus includes a variable displacement compressor. An external information detector detects external information used for the air conditioning. An E/G-ECU controls the output of the power source. An A/C-ECU is connected to the E/G-ECU via a communication line. The A/C-ECU computes a target value of the displacement of the compressor based on the external information. The A/C-ECU sends the computed target value to the E/G-ECU. The E/G-ECU controls the displacement of the compressor based on the computed target value. This is capable of rapidly changing the discharge displacement in accordance with the driving condition of the engine.

摘要： A valve body adjusts opening of a supply passage in response to the position in a valve chamber. A pressure-sensitive member is moved in accordance with the pressure difference between two pressure monitoring points, which are located in an external refrigerant circuit. The movement of the pressure-sensitive member affects the position of the valve body such that the compressor displacement is changed to reduce fluctuations in the pressure difference. A solenoid changes force applied to the valve body so that a set pressure difference, which is a reference value for changing the position of the valve body by the pressure-sensitive member, is changed.

摘要： A compressor includes pistons slidably accommodated in cylinder bores. A head and a skirt are formed at the ends of the piston. The head has a peripheral surface that always contacts the inner surface of the cylinder bore. The skirt is coupled with a swash plate. An annular space opens to the side of the piston. The annular space is located between the head and the skirt. A recess is located on the inner wall of a front housing and extends longitudinally in the axial direction of the piston. A projection is integrally formed on the skirt of the piston to engage with the recess. Rotation of the piston about its axis with respect to the cylinder bore is restricted by the engagement of the projection with the recess. A force acting on the piston in a direction transverse to the axis of the piston is received by the recess through the projection.

摘要： A compressor having a cylinder bores and pistons are disclosed. Each piston moves in the associated cylinder to compress gas therein. Each piston slides on an inner peripheral wall of an associated cylinder to seal a compression chamber. Each piston includes an outer peripheral surface and cavities. The outer peripheral surface has a seal to seal the cylinder and a pressure receiving surface to receive reaction forces from the wall of the cylinder. A low friction layer is formed on the pressure receiving surface. The layer facilitates the sliding movement of the piston with respect to the cylinder.
