摘要： A compressor housing defines a motor accommodating chamber. The pressure in the motor accommodating chamber is equal to the pressure in a suction chamber. A first reservoir chamber is located in a discharge chamber. A second reservoir chamber is defined about the discharge chamber. A communicating passage connects the first reservoir chamber with the second reservoir chamber. A restrictor is located in the communicating passage. An oil return passage connects the second reservoir chamber with the suction chamber. A connecting passage connects the motor accommodating chamber with the suction chamber. Therefore, leakage of electricity is prevented.

摘要： A control valve is used for a cooling apparatus having a compressor including a displacement variation mechanism and an external refrigerant circuit connected to the compressor to form a cooling circuit. The discharge displacement of the compressor is regulated by controlling a control pressure, which acts on the displacement control mechanism. The control valve has a housing and an internal passage. The internal passage includes a valve chamber defined in the housing. A valve body is located in the valve chamber and controls the opening degree of the internal passage. A first pressure sensing structure senses the differential pressure between two pressure monitoring points in the cooling circuit, that is, a primary pressure, and transmits a force corresponding to the primary pressure to the valve body. A second pressure sensing structure senses a secondary pressure, which is different from the primary pressure, and applies the secondary pressure to the valve body. The valve body is positioned in the valve chamber by a combination of forces corresponding to the primary pressure and the secondary pressure, and the opening degree of the internal passage is controlled accordingly.

摘要： A controller normally supplies current the magnitude of which corresponds to a required cooling performance of a refrigeration circuit to a displacement control valve. As a result the compressor displacement is adjusted in accordance with the required cooling performance (usual displacement control). When a vehicle is quickly accelerated, the controller temporarily eliminates the current value to the control valve to minimize the compressor displacement (displacement limiting control). When the control is switched from the displacement limiting control to the usual In displacement control, the controller changes the current value from zero to a target value, which corresponds to the required cooling performance, taking a predetermined restoration time. For an initial period of the restoration period, the current value is set greater than a corresponding value on a direct proportional line, which represents a constant rate of change from zero to the target value. As a result, the control is smoothly and quickly switched from the displacement limiting control to the usual displacement control.

摘要翻译： 控制器通常向位移控制阀提供与制冷回路所需的冷却性能对应的电流。 因此，根据所需的冷却性能（通常的位移控制）来调整压缩机的位移。 当车辆快速加速时，控制器临时消除控制阀的当前值，以最小化压缩机排量（位移限制控制）。 当控制从位移限制控制切换到通常的位移控制时，控制器将预定的恢复时间将当前值从零改变为对应于所需冷却性能的目标值。 对于恢复期的初始期间，将当前值设定为大于直接比例线上的对应值，其表示从零到目标值的恒定变化率。 结果，控制从位移限制控制平稳地快速切换到通常的位移控制。
