Abstract (en)
[origin: EP0087838A1] A capacity control valve for a compressor comprising a suction chamber (1) and a delivery chamber (2) and therebetween a connection (15) controlled by the control valve. The delivery chamber (2) is coupled to a pressure pipe. The control valve consists of a slide (7) provided axially slidable in a closed valve chamber (3, 4, 5 and 6). The wall of the valve chamber is provided with a number of ports (9) in a plane perpendicular to the sliding direction of the slide 7. The ports (3) connect the internal space (3,4) of the valve chamber to the delivery chamber (2). At both sides of the ports (9), the spaces (4 and 3) of the valve chamber have a connector for connections to the suction chamber (1) and pressure pipe respectively. In both of the end positions of the slide (7), a sealing part (12) thereof engaging the valve chamber wall releases the ports (9) at least partly.
