  • Publication number: 20150210817
    Abstract: A melamine-formaldehyde foam comprises from 80% to 98% by weight of at least one inorganic filling material, based on the total weight of the at least one inorganic filling material plus melmine-formaldehyde precondensate used for foam production, wherein the at least one inoganic filling material has a density of at least 3 g/cm3.

  • 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).

  • Patent number: 5287883
    Abstract: The riveting sleeve (6) described is used to connect the component parts (3, 4, 5, 10, 11) of compressor valves (2). The riveting sleeve (6) passes through the valve parts (3, 4, 5, 10, 11) to be connected to one another and is provided with at least one radial groove (16, 22, 26) which starts from the inner or outer generated surface (17, 18) thereof and weakens the wall thickness of the riveting sleeve (6) in this area. On the other side of the generated surface (17, 18) the groove (16, 22, 26) is adjacent either to the wall of a valve part surrounding it or surrounded thereby, or it has opposite it a recess (19, 23, 27) in the valve part (3, 5, 25) adjacent to the riveting sleeve (6). By upsetting the riveting sleeve (6) by means of an applied axial force, the riveting sleeve (6) is deformed radially outwards or inwards in the manner of a bead, it being securely clamped in or on the adjacent valve part.

  • Patent number: 5249595
    Abstract: A valve for a piston-type compressor includes a valve seating with throughflow channels, a closure piece for controlling these channels, a spacer and a spring means urging the closure piece against the valve seating and supported on an arrester which at the same time forms the limit stop for the closure piece. In order to anchor the valve parts on the valve seating before the installation of the valve, at least one sleeve serving as a transport securing means and as an assembly aid is provided, which is secured at one end on the valve seating or on the arrester, and the individual valve parts are pushed in the correct installation position onto the sleeve. The other end of the sleeve is widened. A tension screw passes through the sleeve in an axial direction. The sleeve can be rolled into an undercut annular groove of the valve seating and at the outer surface of the arrester end flush with the latter.
