摘要： A motor-driven compressor includes an electric motor driven by a motor driver, which includes a switching element that converts DC voltage from a battery to AC voltage. A control unit controls the switching operation of the switching element. A temperature detector detects the temperature of the switching element. The control unit suspends the switching operation of the switching element when the temperature detected by the temperature detector rises to a temperature threshold. The temperature threshold includes a first temperature threshold, corresponding to a withstand temperature of the switching element, and a second temperature threshold, which is higher than the first temperature threshold. The control unit switches the temperature threshold from the first temperature threshold to the second temperature threshold when the control unit activates a field weakening control that reduces counter electromotive force generated by the electric motor.

Resilient means are mounted in the cavity for resiliently urging the valve spool from the first end towards the second end of the cavity. A first gas passageway in the plate provides unobstructed fluid communication between the first end of the cavity and the feedback conduit of the compressor. A second gas passageway in the plate provides unobstructed fluid communication between the second end of the cavity and the gas reservoir, where the gas reservoir is in unobstructed fluid communication with the output conduit of the compressor.
