    Abstract: An apparatus controls a variable displacement compressor used in a refrigerant circuit. The compressor includes a drive shaft (6), which is rotated by an engine (E). When the drive shaft (6) rotates, the compressor compresses refrigerant sent from the external refrigerant circuit and discharges the compressed refrigerant to an external refrigerant circuit (30). When the displacement of the compressor is minimized, the circulation of refrigerant in the refrigerant circuit is stopped. The apparatus has a control mechanism (27, 28, CV) for varying the pressure in the crank chamber. A detector (76, 77, 78, 79) detects a physical quantity that reflects the heating status of the compressor. When the compressor displacement is minimized and the quantity detected by the detector (76, 77, 78, 79) indicates that the heating status of the compressor is deteriorating, a controller (70) commands the control mechanism (27, 28, CV) such that the displacement of the compressor is greater than the minimum displacement.

    Abstract: An electric-motor hydraulic pump (10) includes a housing (12) having a stationary internal shaft (14). A pair of cylinder blocks (16,18) are rotatably carried by the shaft (14) within the housing (12), and an array of pistons (22) are slidably disposed with each cylinder block. A yoke plate (20) is mounted within the housing (12) and engages the pistons (22) for determining displacement of the pistons within the cylinder blocks (16,18). Fluid inlet and outlet ports (28) are provided in the housing (12) and are coupled to the cylinder blocks (16,18). An induction motor (30,32) includes a rotor (34) carried by the cylinder block (16,18) for corotation therewith, and a stator (36) mounted within the housing (12) surrounding the rotor. An electronic controller for controlling outlet fluid pressure and flow from the pump (10) includes a plurality of sensors (46,56,58,60) mounted on the housing (12) for sensing operating characteristics of the pump and motor to provide electronic sensor signals as functions thereof. Control electronics (96) are responsive to the sensor signals for controlling fluid pressure and flow from the pump by varying effective displacement of the pump, and by varying the electrical power (current and frequency) applied to the motor.

    Abstract: PROBLEM TO BE SOLVED: To provide an electric compressor capable of protecting a component against thermal damage depending on capability of the component to be protected. SOLUTION: This electric compressor 10 incorporates a compressor mechanism 11, an electric motor 12 for driving the compressor mechanism 11 and a control section 13 for controlling drive of the electric motor 12 into a single casing, and also has a temperature detector 14 to detect the temperature of one or more components composing either one or both of the control section 13 and the electric motor 12 and a current detector 15 to detect a current flowing to the component. Assuming the temperature detected by the temperature detector 14 as the temperature Td, the current detected by the current detector 15 when the temperature detector 14 detects the temperature Td as Id, and a current corresponding to the temperature Td in a temperature characteristic on the current inherent in the component as a current Ia(Td), the control section 13 stops the drive of the electric motor 12 based on a result of comparison of Ia(Td) with Id.
