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).
Claims6
A valve plate (1) made of fiber-reinforced plastic for gas exchange valves of reciprocating piston compressors comprising at least two concentric sealing rings (3), that cooperate with corresponding seating surfaces (4) at the valve seat (5) by way of profiled sealing surfaces (2) and that are connected by way of radial webs (6), wherein the webs (6) are designed to be thinner between the sealing rings (3) along the entire radial extent thereof and on both sides of the valve plate (1) compared to the adjacent thickness of the sealing rings (3), wherein holding means and preferably centering means for the valve springs are designed at least in some of the areas of reduced thickness of the webs (6) on the back side (7) of the valve plate (1) facing away from the sealing surfaces (2).
