Definitions

  • the invention relates to a hollow valve plate for liquid-cooled multi-valve valves of a reciprocating compressor.
  • valve plates thus consist of relatively many items and in the manufacture and assembly are also relatively complicated, they also have the disadvantage that the cylinder-side resulting dead space, so the construction is not to be compressed dead volume, is relatively large, which negatively affects the possible delivery rate of the compressor.
  • Object of the present invention is to provide a valve plate of the type mentioned in such a way that the production and assembly is simplified and that the design-related dead space cylinder remains as small as possible. At least along the cooling channels sealed lamella plate is covered, which in the region of the suction opening (s) in each case one out of the lamellae plate, one-sided integrally connected suction lamella has.
  • the entire valve plate overlapping and clamped together with this between the cylinder and cylinder head lamellae also serve the cylinder side completion of the half-shell cylinder side open cooling channels, which by eliminating the previously formed in the cooled valve plates these channels or final separate second half shell or cylinder-side cover plate not only makes production and installation of such hollow valve plates much easier, but also reduces the cylinder-side dead space by up to 50% (compared to previous versions with two half-shells). Also, the sealing of the entire system is easier because a sealing level is eliminated. Additionally advantageous is the associated weight and cost savings.
  • the lamella plate is permanently connected at least along the cooling channels with the half-shell, preferably welded or glued, which ensures a connection of the lamellar plate with the half shell while sealing only the necessary areas. If further passage openings provided in lamellar plate and / or half shell are also to be sealed off, this can also be done very simply by widening the welding or bonding to these areas.
  • Fig. 1 shows the perspective view of an inventively designed valve plate in exploded view from the side of the suction plate (ie from the cylinder side), Fig. 2 the valve plate after Fig. 1 from the pressure valve side in exploded view and Fig. 3 the valve plate in the assembled state from the side of the welded plate slats with the Sauglamellen.
  • valve plate 1 itself is shown - the cylinder block of a better clarity omitted two-cylinder piston compressor concludes in the presentation Fig. 2 at the bottom of the lamella plate 22 (assembled with the half-shell 3) on - above the half-shell 3 (in the illustration Fig. 2 ), the cylinder head would have to be presented, the suction and pressure channels including corresponding ports, cooling channels and the like.
  • the on the cylinder side unilaterally open cooling channels 4 having half-shell 3 is covered by the sealed at least along the cooling channels 4 fin plate 2, which in Section of the suction openings 5 each have a worked out of the slat plate 2, one-sided integrally connected suction plate 6 has.
  • the slat plate 2 is according to Fig. 3 not only along the cooling channels 4 with the half-shell 3 permanently connected (for example, by the indicated weld bead 7 or a corresponding bond), but also in the area around the pressure openings 8, according to Fig. 2 be controlled on the top of the valve plate by separately attached pressure valves 9. Apart from that, but of course, a separate sealing of these pressure openings 8 would be possible.
  • the hollow valve plate 1 is formed in this way on the suction side of only two parts - the half-shell 3 with the per se open cooling channels 4 and the plate plate 2, which simultaneously provides the function of the suction plate and the completion of the cooling channels 4.
  • the cylinder-side dead space can be significantly reduced by the thin slat plate 2 with respect to a separate cover plate or second cylinder-side half-shell, which has a favorable effect on the degree of delivery of the compressor.
