Variable capacity vane compressor |
摘要 |
A variable capacity vane compressor comprises additional refrigerant inlet ports formed in one of front and rear side blocks of a cylinder accommodating a rotor, and communicating a suction chamber with a compression chamber on a suction stroke, and a control element received in a recess formed in an end face of the above one side block facing the rotor, for rotation to vary the opening angle of the additional inlet ports to thereby control the compression commencing timing of compression medium. At least one spacer is interposed between the control element and at least one of the above one side block and the rotor, for maintaining a predetermined minimum clearance therebetween.
