<p>A pressure valve, especially for rotary piston compressors, which includes a valve housing in the form of a cylindrical sleeve which latter has circumferential through-flow openings or slots which from the inside of the sleeve are covered by a valve closure member comprising resilient lamellae. The valve closure member comprises a pre-bent pre-loaded lattice or grate-shaped metal sheet with parallel longitudinal strips forming the resilient lamellae the ends of which are respectively interconnected by two rim strips. These rim strips rest against both sides of an abutment or counter bearing located opposite the through-flow openings. In the closing position of the valve, the valve closure member tightly engages that inner surface of the sleeve which surrounds the through-flow opening or openings in the sleeve, whereas in the open position of the valve the valve closure member rests against two nearly diametrically oppositely located areas of the inner wall of the sleeve.</p> |
