The invention relates to an actively controlled valve () having a housing () and comprising a displaceably supported valve plate () having aperture openings () and a counter plate () disposed in a fixed manner relative to the housing () and having aperture openings (), wherein the valve plate () is slidably supported relative to the counter plate (), such that the penetration openings () form an open or closed aperture (), and comprising a drive device () driving the valve plate (), wherein the valve plate () is connected to the drive device () by means of a drive spring (), and an actuatable clamping device () is provided for fixing the location of the valve plate ().

Actively controlled valve and method for operating an actively controlled valve

The annular valve (10) comprises a valve seat (11) attached in the housing (1) of the compressor, an absorber (14) attached thereto at a distance and an annular sealing component (12), which can move between the valve seat and the absorber. Helical springs (2), which move the sealing component in the closing direction towards the valve seat, are distributed over its periphery between the absorber and the sealing component. Each helical spring (2) is fastened with one end in the absorber (14). In the region of the other end of each helical spring (2), the sealing component (12) is provided with guide means (6) for the respective spring end.
