Control circuit unit for a variable capacity compressor incorporating a solenoid-operated capacity control valve |
摘要 |
A control circuit unit for controlling the energization of a solenoid of a solenoid-operated capacity control unit incorporated in a a variable capacity compressor, typically, a variable capacity wobble plate type refrigerant compressor for a car air-conditioner, having a switching unit for establishing an electric conduction of the energizing circuit of the solenoid when the solenoid-operated valve is actuated for changing the compressor capacity, and an electric energizing voltage control circuit used to apply a high electric starting voltage to the solenoid emergizing circuit at a predetermined initial starting time of the solenoid, and a low electric retaining voltage required for retention of the energization of the solenoid valve after the predetermined starting time has elapsed.
