Definitions

  • the first and second circumferential groove-shaped formations are in the form of in the main body formed embossed beads.
  • the seal is pressed flat by elastic deformation. This results from the preload forces of the screws on the bead top (increase) and at the edges of the underside of the underside (depression) increased surface pressure.
  • the double-sided thin elastomer coating adapts to the roughness depth of the valve housing and pump mounting surface, so that the surface pressure is not interrupted by surface defects. If this surface pressure has a closed course, as is the case according to the invention, the sealing function is thereby achieved and the flat gasket according to the invention effectively seals high pressure and tank pressure connections between the variable displacement pump and the control valve. Due to the additional course of the second bead or housing pressure bead around all pressure lines, which are already surrounded by high pressure beads, thus a double seal is achieved and ensures that a leak on the

  • the second through-holes pass through cylindrical pins or fixing pins, which are mounted on the regulator or the valve by means of a press fit.
  • the through holes are provided with the above-mentioned retaining lugs, which are manufactured with oversize and at Bend the assembly and firmly clamp or fix the gasket to the cylinder pins.
  • retaining tabs or retaining clips which also serve to fix the seal on the valve and to allow a clear mounting or mounting position.

  • Fig. 1 shows a schematic view of the flat gasket 1 according to the invention, which for sealing a regulator (not shown), for example, to a pump (not shown) is used.
  • the flat gasket 1 is constructed from a substantially plate-shaped main body 2, which is made of an elastomer-coated carrier material.
  • three first through-holes 3 are provided in this embodiment, through which in the assembled state of the flat gasket 1 high-pressure lines (not shown) are passed.
  • the encircling channel-shaped first recess 4 or the annular bead is embossed into the plate-shaped basic body 2 around each of the first through-bores 3.
  • the first recess 4 has a closed course.

Abstract

Le joint plat (1) selon l'invention, en particulier pour l'utilisation dans une machine à piston axial, se compose d'un corps de base (2) essentiellement à la manière d'une plaque et correspondant essentiellement au contour (9) d'un corps de soupape à relier à celui-ci, lequel corps de base est muni d'une pluralité de premiers forages de passage (3), qui sont entourés respectivement d'une première cavité (4) périphérique en forme de gouttière. Une seconde cavité (5) périphérique en forme de gouttière est prévue sur le corps de base en forme de plaque (2), lequel entoure toutes les premières cavités (4) périphériques en forme de gouttières.
