Abstract
A scroll type compressor has a pair of bypass ports which communicate with a chamber being compressed which ports are bored in an end plate of a stationary scroll. An inner surface of a capacity control block of the compressor is separate from the stationary scroll and abuts against the outer surface of the end plate of the stationary scroll, thus forming a recessed portion which communicates with the pair of bypass ports therebetween. One cylinder of the compressor communicates with a suction chamber in a housing and is provided in the capacity control block and a piston operating by a control pressure in accordance with a load of the compressor is disposed slidably in the cylinder. A communicaton hole which communicates with the recessed chamber is opened and closed by the piston, thereby controlling the output capacity of the compressor in the range from 0 to 100%.
