Abstract
In sealing elements (3, 3′, 3″) for automatic compressor valves, composed of synthetic material (12) having embedded fiber reinforcement (11), the fiber reinforcement (11) and/or the surrounding synthetic material (12) in the finished sealing element (3, 3′, 3″) has an inhomogeneous distribution and/or locally different material characteristics under consideration of different local requirements. Near-surface regions (14) may be designed to be free of fiber to avoid fiber breaks and the danger of cracks extending from there, and said near-surface regions (14) may preferably consist of different materials compared to the one in the remaining sealing element (3, 3′, 3″)
Claims11
A sealing element for positioning between a seat surface and a stop surface of an automatic compressor valve, said sealing element being composed of synthetic material with embedded fiber reinforcement, said embedded fiber reinforcement consisting of fibers of random orientation, wherein at least one of said fiber reinforcement and said synthetic material in the sealing element has at least one of an inhomogeneous distribution and locally;
- different material characteristics based on different local requirements and wherein a near-surface region of said sealing element which faces at least one of a seat surface and a stop surface is free of fiber reinforcement un to a depth of at least two times the fiber diameter.
