Abstract
A variable-delivery compressor of a swashplate type having compression chambers wherein compression is effected by reciprocating movements of double-headed pistons slidably engaging a rotating swashplate in a cylinder block. The cylinder block defines compression chambers in cooperation with front and rear valve plates which have discharge ports communicating with front and rear discharge chambers one of which serves as delivery-adjusting discharge chamber. Delivery-adjusting discharge valves are disposed in the delivery-adjusting discharge chamber and carried by an actuator member which is movable between operative and inoperative positions at which the delivery-adjusting valves are operative and inoperative to close and open the discharge ports in the corresponding valve plate. The corresponding valve plate comprises a portion defining a recess opposite to each delivery-adjusting discharge valve. The recess is held in partial communication with the delivery-adjusting discharge chamber even while the delivery-adjusting discharge valve is held in contact with the corresponding valve plate.
