  • Patent number: 5390700
    Abstract: An automatic valve for use in compressors or an otherwise non-return valve has a valve seat with passage channels which are controlled by a shutter blade (16). The shutter blade (16) includes a lock element (27) with concentric rings (19) connected together by radial cross pieces (29). The lock element (27) is guided by flexible guides (26). To enlarge the passage cross section through the valve and to improve the flow conditions, the guides (26), clamped on their outer rim, are guided radially inwardly from the clamping point with an outer cross piece (30); then pass over in the shape of an arch (31) with a relatively large radius of curvature into at least one ring section (32), which extends in the circumferential direction, and is provided with an outwardly directed bend (33), and in turn passes over in an inwardly directed arch (34) with an equally large radius of curvature into an inner cross piece (35), which adjoins the lock element (37).
