Definitions

  • the invention relates to a lamellar valve, in particular for compressors, having a seating plate the throughflow openings of which are covered by several elastic tongues arranged in parallel alongside one another.
  • Lamellar valves conventionally consist of elastic tongues which are fixedly clamped at one end to the seating plate and project with their free ends over the throughflow openings of the seating plate which they cover.
  • lamellar valves consisting of separate tongues
  • the lamellar valves are comparatively simple and have a long service life, in particular because of the independent movability of the individual tongues which work substantially elastically, so that hard impacts are avoided. With the valve opened however the stroke gap defined by the tongues decreases from the free end of the tongues to the clamping place.
  • the invention aims at an improvement of the conventional lamellar valves, in particular with reference to the distribution of the flow over the valve opening area and in relation to the manufacture of the lamellar.
  • a lamellar valve having a seating plate the throughflow openings of which are covered by a plurality of elastic tongues arranged in parallel alongside one another, wherein the free ends of adjacent elastic tongues project alternately in opposite directions over the throughflow openings of the seating plate in a meshing arrangement.
  • the elastic tongues projecting in the same direction are connected at one end by a transverse joining web to form two tongue plates each fixed to the seating plates by oppositely directed tongues.
  • the two tongue plates in this arrangement can have the same form and are simple to manufacture, because their tongues have great lateral spacing from one another.
  • all tongues are formed by a single closure plate which has a closed frame and a meander-shaped cut-out forming the tongues.
  • a single closure plate only, with which however the same functional advantages are achieved as with the use of individual tongues or two tongue plates.
  • a catcher plate forming an end abutment for the free ends of the tongues may be provided, the catcher plate having abutment tongues extending alternately from opposite sides, the free ends of the abutment tongues being bent away from the seating plate.
  • This catcher plate also is comparatively simple to manufacture. It can be punched using the same tools as are used for the closure plate, on which it is merely necessary to bend up the abutment tongues.
  • the catcher plate can also be of divided construction, its two parts having the same shape.
  • FIG. 1 a section in the axial direction through a lamellar valve taken along the line I[ in FIG. 2;
  • FIG. 2 a top plan view of the valve with the catcher plate removed
  • FIGS. 3 and 4 variations of the closure plate.
  • the lamellar valve according to FIGS. 1 and 2 has a seating plate 1 with throughflow openings 2 and a catcher plate 3. Between these and the seating plate 1 a closure plate 4 is clamped, which according to FIG. 2 comprises a closed frame 5 having a meander-shaped cut-out 6. As a result of the cut-out 6 elastic tongues 7 and 7' are formed, which project alternately in opposite directions from opposite sides of the frame 5 towards each other, all the tongues 7 or 7 projecting in the same direction being joined by joining webs 8 or 8', as the case may be, formed by the side parts of the frame 5.
  • the tongues 7 and 7 of the closure plate 4 cover the throughflow openings 2 in the seating plate 1, project ing over the said plate alternately in opposite directions, as can be seen from FIG. 2.
  • the tongues 7 and 7' lift up from the seating plate 1 and rest against the catcher plate 3 which in the embodiment according to FIG. 1 is provided with abutment tongues 9 and 9 which are located above the tongues 7 and 7 of the closure plate 4 and the free ends of which are bent upwards from the seating plate 1.
  • FIG. 3 shows a variation of the closure plate 4 which in that illustration is of two-part construction.
  • the tongues 7 and 7' projecting respectively in the same direction are connected together by a joining web 8 or 8' as the case may be to form a tongue plate 10 or 10'.
  • the two identical tongue plates 10 and 10' are arranged one inside the other with tongues 7 and 7' projecting towards one another, so that when combined they form a closure plate.
  • the tongue plates and 10' are simple to manufacture, and a particular advantage is that the tongues 7 and 7 are spaced at a considerable distance from one another so that the finishing work, in particular the removing of burrs from the edges, is considerably facilitated.
  • FIG. 4 shows a closure plate 4 having flexible guide rods 11 for guiding the closure plate without friction during the stroke movement.
  • the closure plate 4 has tongues 7 and 7 lying adjacent to one another and projecting in opposite directions, the said tongues in each case being connected together by a joining web 8 and 8.
  • the flexible guide rods 11 connect laterally to the joining web 8.
  • throughflow openings 2 of the seating plate are covered by the tongues 7 and 7 and the flexible guide rods 11, and also longitudinal webs 12 provided laterally of the said tongues.
  • a lamellar valve having a seating plate the throughflow openings of which are covered by a plurality of elastic tongues arranged in parallel alongside one another, wherein the free ends of adjacent elastic tongues project alternately in opposite directions over the throughflow openings of the seating plate in a meshing arrangement.
  • a lamellar valve as claimed in claim 1 further having a catcher plate forming an end abutment for the free ends of the tongues, the catcher plate having abutment tongues extending alternately from opposite directions, the free ends of the abutment tongues being bent away from the seating plate.
