Abstract (en)
[origin: EP1081384A2] A scroll-type compressor is disclosed. The compressor has a fixed scroll (11) and a movable scroll (20). Two scrolls (11, 20) respectively have volute portions (32,34) cooperate to form a variable volume gas pocket. The movable scroll (20) moves along a predetermined orbital path to vary the volume of the pocket. A movable base plate (33) has a discharge port (25) that discharges the gas from the pocket when the volume of the pocket is less than a predetermined volume. A valve unit (26, 29, 30) connects and disconnects the discharge port (25) with the gas passage. The valve has a movable valve body (39) movable between two positions open and close the discharge port (25). <IMAGE>
