Abstract: To provide a high-voltage apparatus control device capable of judging the connection state of a connector and discharging residual charge in a short time. A control device 1 controls an electric compressor and is provided with an interlock loop 4 annexed to a connector 9 for connecting the electric compressor to an HV battery 17. The control device 1 detects connection/disconnection of the connector 9 on the basis of the state of the interlock loop 4 and forcibly discharges residual charge in an internal smoothing capacitor 14 when disconnection of the connector 9 is detected.

Abstract: The present invention quickly stops rotation of an electric compressor while preventing damage to switching elements. An electric compressor 1 comprises a motor drive circuit 52 having multiple switching elements IGBT Q1 to Q6, a control unit 53 that controls driving of the multiple switching elements IGBT Q1 to Q6 and drives a motor 4, and a current detection unit 54 that detects a current flowing through the motor drive circuit 52. The control unit 53 performs stop control that stops rotation of the compression mechanism 3 by performing braking control that controls drive of predetermined switching elements IGBT (Q2, Q4, Q6 and the like) among the multiple switching elements IGBT Q1 to Q6. In the brake control, when the detected current value I is lower than the first threshold I1, the control unit 53 adjusts the drive pattern of the predetermined switching elements IGBT (Q2, Q4, Q6 and the like) in order to prevent the detected current value I from exceeding the second threshold I2 that is lower than the first threshold I1.

Abstract: [Problem] A scroll compressor is provided which is capable of effectively reducing a pressure loss in a pathway extending from a discharge space to a discharge port.
[Solution] The scroll compressor includes a discharge space 27 formed in a compressing mechanism cover 9 of a housing 11, a discharge hole 26 which is formed in a fixed scroll 21 and discharges a compressed refrigerant to the discharge space, a discharge port 51 which discharges the refrigerant to the outside of the housing, a relief passage 71 which communicates the discharge space and the discharge port with each other, and a differential pressure valve 74 which is provided in the relief passage and opens in accordance with a pressure difference between the discharge space and the discharge port. The relief passage opens in the discharge space above the discharge hole.-

Abstract: Provided is an electromagnetic clutch capable of shortening, even in a low temperature atmosphere, the fuse reaction time from when a rotating shaft is locked, while preventing or suppressing malfunction of the thermal fuse. An electromagnetic clutch 1 is equipped with a rotor 2, an armature 3, an electromagnetic coil unit 4, a thermal fuse 5, and a thermally actuated switch 6. The thermally actuated switch 6 is connected in series to an electromagnetic coil 41 of the electromagnetic coil unit 4 along with the thermal fuse 5. When a temperature of the thermally actuated switch 6 exceeds a switching temperature (predetermined temperature) Ts, the thermally actuated switch 6 is displaced in an electric power supply OFF direction, and thereafter, it is displaced in an electric power supply ON direction due to a reduction in temperature. The thermally actuated switch 6 turns ON/OFF the electric power supply to the electromagnetic coil 41 such that the thermal fuse vicinity temperature T1 does not exceed the operational temperature Tf of the thermal fuse 5 due to self-heating of the electromagnetic coil 41 itself generated by the electric power supplied to the electromagnetic coil 41, thereby preventing malfunction of the thermal fuse 5 due to self-heating of the electromagnetic coil 41.

Abstract: A swash-plate-type variable displacement compressor is provided with a rotationally-driven drive shaft, a lug plate integrally fixed to the drive shaft, a swash plate fixed in a manner capable of being variably inclined to the drive shaft, a link mechanism for coupling the lug plate and the swash plate while permitting the variable inclination; and an actuator which is arranged between the lug plate and the swash plate and which uses pressure to change an inclination angle of the swash plate. The actuator has a cylindrical member which extends from a surface of the lug plate toward the swash plate, a bottomed cylindrical member fitted capable of being relatively displaceable to an outer peripheral surface of the cylindrical member, and a coil spring which is arranged in an inner space of the actuator, and which biases the bottomed cylindrical member in a direction which is away from the lug plate.
