    The hollow valve plate 1 of a reciprocating compressor has a single half-shell (3) with cooling channels (4, 5) open to the side of the pressure valves (8), which cover plate (2) is preferably welded or glued at least along the cooling channels (4, 5) ) is covered, which is formed in the region of the pressure valves (8) as a stroke limiter (9) for inserted closing plates (10). This simplifies the manufacture and assembly of such valve plates.

    Hollow valve plate
    The invention relates to a hollow valve plate for liquid-cooled valves of a reciprocating compressor, with a half-shell with cooling channels open on one side, which is covered by a sealed at least along the cooling channels thin cover plate, which aulweist out of this, one-piece integrally connected elements of the valves aulweist.
    Especially when used as a brake air compressor in motor vehicles or similar, often long time high-performance applications, it is necessary to actively cool the at least one mammal valve and a pressure valve-carrying valve plate to avoid overheating in this area and also pushed over the Druckventiie Pre-cool compressed air, at least to a certain extent, before it is then usually cooled in the cylinder head area before exiting. For this purpose, according to the state of the art, partially hollow or with cooling channels provided valve plates are used, the cooling chambers or channels are connected to a liquid cooling of the reciprocating compressor or together with this to the liquid cooling of an internal combustion engine used for vehicle propulsion.
    The prior art for producing such hollow valve plates is usually soldering. The individual parts to be soldered consist either of a number of thin stamped steel plates, which are connected in packages to form a unit, wherein from meandering recesses and regional recesses of the middle plates together with the closed up to inlet and Ableitöffnungen outer plates cooling channels or - create spaces. On the other hand, however, there are also designs with two channels open on one side or areas of protruding half-shells (mostly of gray cast iron), which then form closed three-dimensional channels or spaces in the interior during assembly. In both variants, usually suction lamellae and pressure lamellae are fastened separately in the end via receptacles or the like on the valve plate.
    Apart from the fact that the known 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.
    Furthermore, from WO2011 / 124502A1 a hollow valve plate of the aforementioned type has become known in which a lamellar plate known per se, for example, also from DE16281B7A1 or EP846247A1, covering the entire valve plate and clamped together with this between the cylinder and the cylinder head, is also used simultaneously
    821AT Linderseitigen conclusion of the half-shell in the cylinder side open cooling channels is used. By eliminating the previously formed in the cooled valve plates these channels or final separate second half-shell or cylinder-side cover plate was thus not only the production and installation of such hollow valve plates significantly simplified, but also significantly reduced the cylinder-side dead space. Also, the sealing of the entire system was easier because a sealing level is eliminated. Additionally advantageous was also the associated weight and cost savings.
    Object of the present invention is to improve a hollow valve plate of the type mentioned so that the advantages already achieved can be obtained unchanged regardless of the specific configuration of the suction side of the valve plate and thus for a larger number of different designs of reciprocating compressors.
    This object is achieved according to the present invention in that the half-shell to the side of the pressure valves has open cooling and / or media channels, which are covered and sealed by the worked out, one-sided connected Hubbegrenzer the inserted closing plates of the pressure valves having cover. It is thus used to cover the pressure side towards open channels again at the same time to take over a partial function of the pressure valves. Here now not to take over the closing function of these valves themselves, but in an advantageous manner to take over the function of Hubbegrenzer, which after installation of the hollow valve plate, wherein the closing plates of the pressure valves are inserted and covered by the overlying cover plate with the Hubbegrenzern, a closed mounting unit arises, which requires no additional retaining elements for the pressure valves, which greatly simplifies the storage and installation.
    The cover plate is connected in a preferred embodiment of the invention, at least along the channels, and preferably also around the Abströmöflhungen the valves with the half shell, preferably welded or glued, which ensures a reliable connection of the cover plate with the half shell while sealing only the necessary areas , If further passage openings provided in the cover plate and / or the half shell are also to be sealed off, this can also be done very simply by widening the welding or bonding to these areas.
    According to a particularly preferred embodiment of the invention, the valve plate on its suction side on another cover plate, which has in the region of the mammal openings each one out of the cover plate, one-sided integrally connected suction lamella and optionally on this side existing cooling and / or media channels from 2 82 sealed, preferably welded or glued, covered. This results in an extremely advantageous combination of the present invention with the above-mentioned prior art, the plates opens the most diverse design options for such valve.
    The invention will be explained in more detail below with reference to the embodiment schematically illustrated in the drawing. 2 shows the same valve plate in the assembled state from the pressure side (top side in FIG. 1) and FIG. 3 shows the valve plate from the suction side (in FIG below)
    Shown in all figures, only the valve plate 1 itself - the cylinder block one of the better clarity omitted two-cylinder piston compressor closes in the illustration of FIG. 1 and 2 at the bottom of the valve plate - above would be imagined in these figures, the cylinder head, the suction and Compression ducts including corresponding connections, cooling channels and the like.
    The here according to FIG. 1 and 2 only on the pressure side (top) cooling channels 4,5 (or not shown media channels, for example, control air or the like) having half-shell 3 is of a least along the cooling channels 4, 5 (as well as here Covered around the inflow openings 6 of the mammal valves 7) sealed cover plate 2, which worked out in the region of the pressure valves 8, one-sided connected Hubbegrenzer 9 for the inserted closing plates 10 (FIG. 1) of the pressure valve 8. The cover plate 2 is shown in FIG. 2 not only along the cooling channels 4, 5 and the half-shell 3 permanently connected (for example, by the indicated weld bead 11 or a corresponding bond), but also in the area around the inflow openings 6 to the mammal valves 7, which 3 are controlled on the underside of the valve plate of separately attached suction blades 12. Apart from that, however, a further continuous cover plate could be arranged on the suction side, which has in the region of the mammalian openings each out of this further cover plate, one-piece integrally connected suction lamella, which (similar to the pressure side) in addition also optionally present on this page other cooling and / or media channels could be covered sealed.
    The illustrated valve plate 1 is the pressure side of only four parts formed - the half-shell 3, the cover plate 2 with the stroke limiter formed thereon 9 and the inserted two closing plates 10 of the pressure valves. There are thus fewer components associated with less manufacturing and assembly costs and less weight and lower costs. A further improvement could be achieved as mentioned on the suction side by the use of another cover plate with integrated suction lamellae. 3

    Only for the sake of completeness is here further still on dowel sleeves 13 for the correct placement of the valve plate 1 between the cylinder and cylinder head and fasteners 14, 15 for the Sauglamellen 12 of the mammal valves 7 to the valve plate 1 to refer. 4
