Abstract
A variable delivery compressor containing a plurality of compression chambers and reciprocatory compression pistons is adapted for use in an air-conditioning circuit of a vehicle. The compressor has a suction chamber communicating with the compression chambers by way of a plurality of suction valves, some of which are capable of being deformed by a valve pressing mechanism from a first position, where the refrigerant is compressed, to a second position where the compression of the refrigerant is partially ineffective. The valve pressing mechanism contains an axially movable spool actuated by an actuating unit controlled by a cooling-load responsive control unit.
