Title:

VARIABLE DISPLACEMENT TYPE COMPRESSOR

Document Type and Number:

Japanese Patent JPH06280745

Kind Code:

A

Abstract:

PURPOSE: To prevent incurring of a power loss during high compression as delivery capacity is rapidly reduced even when a delivery pressure is low.

CONSTITUTION: In an extraction valve mechanism A, when a suction pressure Ps is reduced to a value lower than a set suction pressure, the opening of an extraction steam passage 22 running between a crank chamber and a suction chamber is cut out. A feed valve mechanism B is operated at a delivery pressure Pd independently from the extraction valve mechanism A. When the delivery pressure Pd is reduced to a value lower than a set delivery pressure, the opening of a feed passage 23 running between a delivery chamber and a crank chamber is released.
