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.

The valve chamber has an opening to accommodate an electrically operative control valve. The control valve controls pressure in the control chamber due to an external electrical signal. An electrical power supply line is connected to the control valve, the power supply line being in contact with an opening of the valve chamber. The valve chamber opening is surrounded by a circumferential wall. An agonic surface formed on the circumferential wall is constituted of a rounded surface formed by rounding a corner of the opening and/or a chamfered surface formed by chamfering a top of the opening, and is formed on a part of or the entire circumferential wall. The power supply line is to be in contact with the agonic surface.

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 displacement control apparatus controls the displacement of a variable displacement controller. A drive shaft of the compressor is driven by an engine. Torque acting on the drive shaft represents the displacement. The apparatus includes a control valve, an air conditioner controller and a compressor controller. The control valve changes the compressor displacement. The air conditioner controller produces a torque setting signal, which represents a target torque, to the compressor controller. The compressor controller changes the valve opening based on the torque setting signal such that the actual load torque matches the target torque value. Accordingly, the compressor is controlled according to the torque. The air conditioner controller may send the torque setting signal to an engine controller, which eliminates the need for load torque maps.

摘要： An air conditioner having a refrigerant circuit that maintains a high cooling efficiency and a sufficient amount of oil returned to a compressor even if the flow rate of refrigerant is decreased due to a low cooling load is provided. The refrigerant circuit includes a condenser, an expansion valve, an evaporator and a variable displacement compressor. The expansion valve is normal-charge type. A control valve adjusts the pressure in a crank chamber based on the value of a current from a controller and on a pressure difference between two pressure monitoring points, which are located in the refrigerant circuit. Accordingly, the compressor displacement and the flow rate of refrigerant in the circuit are controlled.

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 refrigerant circuit includes a compressor and an expansion valve. The expansion valve is connected to a discharge muffler of the compressor by a high pressure conduit. The expansion valve is also connected to a suction passage of the compressor by a low pressure conduit. The high pressure conduit includes a condenser and the low pressure conduit includes an evaporator. A check valve is located between the discharge muffler and the high pressure conduit to selectively connect and disconnect the high pressure conduit with the discharge muffler. A relief valve is attached to the discharge muffler upstream of the check valve. If the pressure in the compressor is abnormally high when the check valve closes, the relief valve releases the abnormally high pressure from the discharge muffler. Therefore, if the check valve fails to function, the relief valve prevents the pressure in the compressor from being abnormally high.

摘要： A variable displacement compressor having a pressurizing passage, which extends through a cylinder block. The pressurizing passage connects a discharge chamber and a crank chamber. A valve is arranged in the pressurizing passage. A drive shaft rotates and produces centrifugal force that causes the valve to open the pressurizing passage. The pressure of the crank chamber is increased when the rotation of the drive shaft is accelerated thereby opening the pressurizing passage with the valve. This moves a swash plate such that its inclination, relative to a plane perpendicular to the drive shaft, decreases. As a result, the compressor shifts from a maximum displacement state to a minimum displacement state, which improves the acceleration performance of an engine connected to the compressor. Furthermore, the displacement of the compressor in the minimum displacement state is 50% of that in the maximum displacement state. This prevents an excessive decrease in the cooling capability of the compressor.
摘要翻译：一种可变排量压缩机，其具有延伸穿过气缸体的加压通道。加压通道连接排气室和曲轴室。阀设置在加压通路内。驱动轴旋转并产生使阀打开加压通道的离心力。当驱动轴的旋转加速时，曲柄室的压力增加，从而用阀打开加压通道。这使得斜盘相对于垂直于驱动轴的平面的倾斜度减小。结果，压缩机从最大位移状态向最小位移状态转变，这提高了连接到压缩机的发动机的加速性能。此外，压缩机在最小排量状态下的位移是最大排量状态的50％。这防止了压缩机的冷却能力的过度降低。
