Abstract
A variable displacement compressor which prevents leakage of a refrigerant flowing directly into a suction chamber without passing via a crank chamber at a time of a minimum discharge displacement operation, thus making it possible to prevent an increase of a minimum discharge displacement by increasing a refrigerant pressure in the crank chamber, and in addition, making it possible to prevent insufficient lubrication of sliding portions and the like in the crank chamber.
