    Abstract: The valve plate (6) which is spring-loaded against the valve seat (2) of the ring valve comprises individual annular plates (10) disposed over the passage channels (1) of the valve seat, plus a support plate (11) which lies jointly on all the annular plates (10) on that side thereof facing away from the valve seat (2) and transfers the force of the spring elements (18) which act on it. The annular plates (10) can be bevelled both on the sides facing the valve seat (2) and on the sides facing away from the valve seat (2).
