Abstract
The present invention contemplates a delivery control valve arrangement adapted for use in a refrigerant gas compressor of double-acting swash plate type in which its delivery capacity can be varied automatically by placing the compression chambers on one side of the compressor under 'loaded' and 'unloaded' conditions alternately in response to the cooling load. The valve arrangement includes valve means for establishing fluid communication passages for selective application of discharge and suction pressures of the compressor to a plunger movable between two positions corresponding to the loaded and unloaded conditions, respectively, and actuator means operable in response to evaporator-suction or suction-atmosphere pressure differential for actuating the above valves.
