Abstract
A valve plate (1) made of fiber-reinforced plastic for gas exchange valves for reciprocating piston compressors comprises at least two concentric sealing rings (3) which cooperate with corresponding sealing surfaces (4) at the valve seal (5) by way of profiled sealing surface (2) and that are connected by way of radial webs (6). In order to improve the flexibility of the valve plate (1) and the sealing behavior, the webs (6) are designed thinner along the entire radial extent thereof between the sealing rings (3) on both sides of the valve plate (1) compared to the adjacent thickness of the sealing rings (3).
