Definitions

  • the invention relates to a valve seat plate, in particular for piston compressors, with at least three superimposed individual plates, which on the one hand have continuous channels for the medium to be controlled and, on the other hand, delimit cavities for cooling medium between them.
  • Valve seat plates constructed from several individual plates are known, for example, from DE-AS 1 142 478 and US Pat. No. 2,449,408, respectively, and enable the relatively simple production of the channels or cavities integrated in the seat plate. While only channels for the medium to be controlled are formed in the training according to the document mentioned in the first place with the aid of the correspondingly recessed central plate, an arrangement of the type mentioned at the outset is known from the second-mentioned US PS, in which in addition to Channels for the medium to be controlled and cooling rooms or channels between the individual plates are defined.
  • valve seat plates have been cast in one piece by means of a croning core for the cavities, which of course has limitations in terms of shape and thickness due to limits of Casting technology and a high control and cleaning effort for the cavity.
  • the object of the present invention is to improve a valve seat plate of the type mentioned in such a way that the disadvantages of the known arrangements of this type are avoided and that, in particular, a valve seat plate is created in a simple and easy-to-assemble manner in which the correct positioning of the individual plates and their sealing is facilitated or improved in the flow area.
  • the channels are arranged in bushings which are continuous over the thickness of the valve seat plate and are sealed off from the cavities.
  • the components delimiting the channels are thus automatically positioned correctly.
  • the thickness tolerance of the punching center part is not dependent on a separate part for the pressure medium bores.
  • the continuous channels for the medium to be controlled are independent of the possible misalignment of the individual plates and the quality of the connection, e.g. the soldering.
  • the individual components of the valve seat plate can be produced from their respective function or production of adapted material, and a wide variety of combinations are possible.
  • the wall thicknesses of the bushings used for the channels can be made much thinner than, for example, a cast in one piece, so that improved heat transfer conditions result. All individual components of the valve seat plate can be designed so that no machining is required after the connection.
  • the middle (s) single plate (s) in the area of the sleeves with the formation of cavities for the cooling medium is (are) excluded and that the sleeves have shoulders for supporting and exact positioning of the outer single plates.
  • the bushes can have an enlarged heat transfer surface, preferably rib-like outer contours, in the region of the cavities. Together with the already mentioned possibility of making the sleeves thin-walled, this results in a particularly good heat dissipation for cooling the most stressed areas.
  • the middle (s) individual plate (s) is (are) fixed in their relative position by means of separate centering parts, preferably inserted sleeves which are continuous over the thickness of the valve seat plate. Since the channels for the medium to be controlled are guided independently of the central individual plates in the bushings used, the central individual plates, or the possibly only central individual plate, can be fixed in position in the aforementioned simple manner.
  • the bushes and the individual plates can consist of different materials, which gives the most diverse possibilities for taking into account the special loads and also the production processes.
  • the sleeves are soldered to the individual plates, with which one can allow tight and permanent connections to be achieved even within wide limits of different materials.
  • FIG. 1 shows a cross section through a valve seat plate according to the invention along the line I-I in FIG. 2, and FIG. 2 shows a plan view of the valve plate according to FIG. 1.
  • the valve seat plate 1 shown for a piston compressor or the like, not shown, has three superimposed individual plates 2, 3, 4, in which continuous channels 5 for the pressure medium to be controlled, a cavity 6 for cooling medium, and a suction chamber 7 for the supply of the to be compressed Medium are trained.
  • the channels 5 are arranged in bushes 8 which are sealed over the entire thickness of the valve seat plate and sealed with respect to the cavity 6 (could also be formed by a plurality of cavities which are divided and connected to supply and discharge lines for cooling medium) and are assembled in the assembled state (not shown here) of the whole Valve on the upper side covered by a spring-loaded valve flap or the like.
  • the cavity 6 is defined here by a corresponding recess in the central individual plate 3, the contour of which is indicated by dashed lines in FIG. 2 and is designated by 9. On the top and bottom, the cavity 6 is delimited by the individual plates 2 and 4 and has overflow openings 10 to the cylinder head (not shown) on the inflow and outflow sides.
  • the suction chamber 7 is delimited on the lower side in the illustration by the lower individual plate 4, which has inlet slots 11 which are covered from the underside in the assembled state of the entire valve by means of a corresponding valve plate.
  • the middle single plate 3 has three webs 12 in the area of the suction space 7 - at the top, the suction space 7 is open at the top through an opening, the contour of which is designated by 13 in FIG. 2, in the upper single plate 2 and usually goes directly into one connected Intake line (not shown here) or the like.
  • the middle single plate 3 is thus excluded in the area of the sleeves 8 for the channels 5 carrying the pressure medium to form the cavity 6, the sleeves 8 here having paragraphs 14 in the area of their lower end for support and precise positioning on the lower single plate 4.
  • Enlarged bores 15 are provided in the area of the upper individual plate 2, which allow the sleeves 8 and the lugs 14 to be inserted from the top.
  • an enlarged heat transfer surface is provided on the outside of the bushes 8, which preferably have a rib-like outer contour 16 for this purpose.
  • the middle single plate 3 is fixed in its relative position by inserted separate sleeves 17, which are continuous over the thickness of the valve seat plate 1, whereby due to the independence of this position fixing of the design of the channels 5 in the bushes 8, no particular accuracy is required in this connection.
  • the sleeves 8 can be made of different material from the individual plates 2, 3, 4 and can be soldered to the individual plates 2, 4, which allows a wide variety of requirements to be taken into account when selecting the material.
  • the valve Due to the possibility of making the wall thicknesses of the sleeves 8 relatively thin and to increase the surface area for the coolant flow by designing the outer contour 16 of the sleeves, the valve as a whole can Performance (degree of delivery / final pressure) can be increased - the higher temperatures that occur can be easily dissipated by the above-mentioned improvements and can thus be controlled.
