Title:
POWER REDUCTION DEVICE AT TIME OF UNLOADING MOTOR COMPRESSOR
Document Type and Number:
Japanese Patent JP3084552
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To reduce electric power consumption of a motor at the time of unloading a motor compressor.
SOLUTION: An air vent mechanism 31 and a three-way solenoid valve 32 operated by such as an electromagnetic solenoid 33 are provided in the middle of a C pipe 27 which connects an oil chamber 12 with a chamber 23c so as to vent compressed air in the chamber 23c at the time of unloading a motor compressor. Therefore, a suction air closing valve 17 closes a suction port 16 of a cleaner 15 to prevent the suction of the air, whereby a pressure within the oil chamber 12 can be decreased. Accordingly, both load and electric power consumption of a motor 11 can be reduced at the time of unloading.
