ABSTRACT:
A compressor plate valve has a valve seat, a valve guard and at least one valve plate which is mobile to-and-fro therebetween to control passage channels provided in the valve seat. To enable the compressor to be switched to idle running, a lifting device is provided for keeping the valve open. This comprises a seating plate which is disposed mobile between the valve seat and the valve plate in the direction of the lifting movement and has valve ports aligned with the passage channels in the valve seat and connection apertures corresponding with the passage apertures in the valve plate. The lifting force is applied to the seating plate by means of a control device.
