ABSTRACT:
A variable capacity vane type compressor has an unloading mechanism operative to relieve a part of compressed fluid from a working chamber when in its compression stroke and an additional mechanism for controlling the suction of fluid into the compressor. The additional mechanism has a spool valve movable to a position to restrict the opening area of the compressor suction port. The spool valve is disposed in a passage communicated with the suction port and with a working chamber when in its compression stroke. The spool valve is formed therein with another passage which, when the spool valve is in the position to restrict the suction port, communicates the compression chamber with the suction port to relieve a part of the compressed fluid.
