Definitions

  • the invention relates to a valve set for piston compressors, with a suction valve and a pressure valve arranged concentrically therewith, each of these valves having a seat plate provided with openings and a valve plate associated with the suction valve and the pressure valve arranged between these two seat plates, which are parallel to one another Extend levels.
  • valve set is known from Fig. 2 of DE-AS 1812580.
  • one of the two valve plates is annular and concentrically surrounds the other valve plate.
  • adjoining link arms are provided, via which the valve plates are held axially movable between the seat plates by extending through the free ends of the link arms, pins which are attached in the seat plates.
  • the seat plates themselves are clamped together by a central screw-nut connection.
  • This type of valve set requires a relatively large diameter of the valve set, which is associated with a correspondingly large space requirement on the compressor. It is also possible that the valve plates hit hard on the opposite seat plate during their opening movement, which can lead to damage to the valve plates.
  • the invention has for its object to improve a valve set of the type mentioned so that its diameter and thus its space requirements are reduced and that the risk of breakage of the valve plates is reduced.
  • the valve set consists essentially of two stacked seat plates 1 and 2 and two between them with axial spacing and concentrically attached valve plates 3 and 4.
  • the seat plate 1 forms with its central part and the valve plate 3 together a suction valve for one Compressor, not shown, whose compression space 5 extends below the seat plate 2.
  • a pressure valve with an annular cross section is separated from the outside Ring part of the seat plate 2 and the annular valve plate 4 is formed.
  • the seat plate 1 has slot-like openings 6 which run on circular arcs concentrically to the central axis 7 of the valve set, but do not extend over an entire circumference.
  • the seat plate 2 slot-like openings 8 are provided, the course of which is equal to that of the openings 6, but which are arranged offset by a half radial division to the openings 6 to the outside.
  • the openings 8 widen towards the compression space 5 in a diffuser-like manner.
  • the valve plate 3 of the suction valve is pressed against the seat plate 1 by eight springs 9.
  • the springs 9 are arranged in corresponding recesses 9 'of the seat plate 2 and protrude through holes 9' in the damper plate 24.
  • the valve plate 3 of the suction valve is surrounded by a concentric annular damper plate 23 for the annular valve plate 4 and extends in the same plane as the valve plate 3.
  • the annular valve plate 4 is pressed against the seat plate 2 by four springs which are not visible in FIG. 1. These springs thus correspond to the springs 9, but are distributed over the area of the valve plate 4 in the seat plate 1 housed.
  • the seat plate 2 also has slot-shaped openings 12 which correspond to the openings 6 in the seat plate 1 and which likewise run on a circular arc, but do not extend over the entire circumference.
  • the openings 12 in the seat plate 1 are assigned openings 13 which, corresponding to the openings 8, are offset from the openings 12. Breakthroughs aligned with the inside openings 13 are located both in the damper plate 23 and in the valve plate 4.
  • valve plate 3 is connected via four outer link arms 3 'with a mounting ring 3 ⁇ .
  • This ring 3 ⁇ is surrounded by a mounting ring 23 ⁇ , to which the damper plate 23 connects via four link arms 23 '.
  • the annular valve plate 4 is connected via four link arms 4 'with a mounting ring 4 Befest Trents.
  • This ring 4 ⁇ surrounds a mounting ring 24 ⁇ for the damper plate 24 which is connected via four outer link arms 24 'to the mounting ring 24 ⁇ .
  • the fastening rings 3 ⁇ and 23 ⁇ and 4 ⁇ and 24 ⁇ are clamped gas-tight between the seat plates 1 and 2, a spacer ring 25 being inserted between the fastening rings 3 ⁇ , 23 ⁇ on the one hand and 4 ⁇ , 24 ⁇ on the other hand.
  • the clamping force is applied by means of four screws 16, only one of which is visible in FIG. 1 and with which the seat plates 1 and 2 are clamped together.
  • a semicircular bulge 17th (Fig. 2 and 3) provided for the screws 16.
  • the damper plate 23 has four bulges 18 distributed over the circumference (FIG. 2), through which extend the springs (not shown) which press the valve plate 4 against the seat plate 2.
  • the gas to be compressed flows in the direction of arrow 10 through the central part of the seat plate 1, the valve plate 3 being moved downward against the force of the springs 9 against the damper plate 24, so that the gas passes through the openings 6 and 8 into the compression space 5 arrives.
  • the compressed gas flows out of the compression space 5 via the openings 12 and 13 in the direction of the arrow 14, the valve plate 4 lifting off from the seat plate 2 and resting on the damper plate 23.
  • the supply of the gas to be compressed (arrow 10) and the discharge of the compressed gas (arrow 14) are separated by an annular, closed wall, which is indicated in FIG. 1 by the dash-dotted lines 15.
  • valve and damper plates 3, 23 and 4, 24, initially produced as one piece, are divided into the two plate parts 3, 23 and 4, 24 at the end of the processing by a laser cut 32.
  • a laser cut 32 When cutting the cut 32, which is otherwise made as a circular line, a small, inwardly jumping semicircular movement is carried out, as a result of which the fastening rings 4 ⁇ and 23 ⁇ receive a nose 33 which projects into a semicircular groove. This causes a relative rotation of the matching plates 3, 23 and 4, 24 avoided during assembly.
  • the bulges 17 in Fig. 2 and 3 can be shifted counterclockwise up to the 45 ° line, the transition region between the handlebar arms 23 'and 4' and the damper plate 23 or valve plate 4 is also moved or is dimensioned somewhat narrower than in Fig. 2 or 3.
  • An embodiment modified in this way has the advantage that, for example, the valve plate 3 - if it shows signs of wear on the surface interacting with the seat plate 1 - can be turned so that the surface previously in contact with the springs 9 then interacts with the seat plate 1.
