LUBRICANT BACK-FLOW PREVENTION MECHANISM OF COMPRESSOR

摘要

PROBLEM TO BE SOLVED: To provide a lubricant back-flow prevention mechanism of a compressor that does not cause a back flow of the lubricating agent even when a speed of a motor drops below a predetermined rotating speed due to an electrical power troubles of user, the compressor being of a lubricant cooling type.;SOLUTION: A control unit 1 is coupled to a motor 3. The control unit 1 closes a solenoid valve 2 when the rotating speed of the motor 3 drops below the predetermined speed to stop supply of the lubricant to a compressor body 4.;COPYRIGHT: (C)2009,JPO&INPIT
