Variable-capacity scroll-type compressor
 A scroll-type compressor has a stationary scroll and a moving scroll which is orbitted about the center of the stationary scroll. A valve chamber, a first by-pass, and a second by-pass are formed in the end plate of the stationary scroll. The first by-pass communicates between the inside of the valve chamber and one of the compression chambers formed by the scrolls, and the second by-pass communicates between the inside of the valve chamber and the outside of the end plate of the stationary scroll. The valve chamber houses a plate-shaped valve which is moved by fluid pressure between a closed position, in which it blocks the by-passes, and an open position, in which working fluid can flow between the two by-passes. Working fluid at either discharge pressure or suction pressure can be introduced into the valve chamber to the rear of the valve through a connecting pipe which is connected to the valve chamber and a 3-way solenoid valve.
