VARIABLE ROTARY COMPRESSOR AND CAPACITY VARYING DEVICE FOR VARIABLE ROTARY COMPRESSOR

摘要

PURPOSE: A variable rotary compressor and a capacity varying device for the same are provided to improve the reliability in the opening/closing operation of a piston which opens or closes a feedback path by employing a solenoid coil of a small capacity. CONSTITUTION: A variable device for a variable rotary compressor includes a piston(21) for opening/closing a feedback path(101c) communicated with the inside of a cylinder(101) and a suction hole by back and forth movement. A guide element(22) guides the back and forth movement of the piston by moving in a predetermined direction. A solenoid coil(23) and an elastic element such as a spring(24) supply movement force to the guide element.
