Definitions

  • the invention relates to a sealing arrangement for a coupling for refrigerant pipes from a first coupling piece tightly connected to a first line end piece and a second coupling piece tightly connected to a second line end piece, wherein both coupling pieces are joined together by fastening means such that the line end pieces each have a bore in the coupling pieces connected to each other and the two coupling pieces each have on the side facing the other coupling piece a radially extending Dichtfizze and is provided as a fastening means only a single, laterally offset from the Dichtfiumbleen arranged screw, wherein at a distance from the screw on the side which the Dichtfiamba the coupling pieces is remote, a non-compressible shaped body is arranged as a spacer between the coupling pieces, which is designed such that when screwing the Kupplungsstü A lever effect is produced which leads to the uniform compression of a sealing ring arranged between the sealing surfaces of the coupling ring, wherein the sealing ring is held by a designed
  • the sealing ring When installing such a seal, the sealing ring must be positioned by hand on the sealing surface and then fixed with the cap. One-handed installation is therefore not possible.
  • the plastic cap on its one coupling piece facing away from the retaining lugs and axial end has at least one radially inwardly facing projection which is formed so that the sealing ring is clipped into the plastic cap so that the sealing ring in clipped Position between the retaining grooves and the at least one projection is held in the plastic cap.
  • This embodiment has the advantage that the sealing ring before assembly on the coupling piece with the holding device forms a unit that can be mounted with only one hand on the coupling piece.
  • the plastic cap shown in the figure has a body 1 made of an elastic plastic with a main bore 2 and three side bores 3 and 4.
  • the secondary bores 3 serve as a positioning aid against coupling pieces, not shown here
  • the secondary bore 4 serves as a through hole for a screw, also not shown, with which the coupling pieces are screwed together.
  • the plastic cap has in the main bore 2 in the radial direction projecting retaining lugs 6, which are arranged on a first, lying in the drawing below axial end of the main bore 2 of the plastic cap.
  • Retaining tabs 6 is dimensioned such that an insertable into the main bore 2, not shown Sealing ring is prevented from the retaining lugs 6 at the passage through the main bore 2.
  • two radially inwardly facing projections 7 are arranged, whose radial projection length is dimensioned so that the sealing ring, not shown, taking advantage of the elasticity of the body 1 of the plastic cap on the projections 7 away on the retaining lugs 6 can be introduced into the main bore 2.
  • the elasticity of the body 1 thereby causes the projections 7 to spring back after positioning of the sealing ring in its original position and thus prevent the sealing ring from falling out of the main bore 2.
  • the sealing ring can be positioned captive in the plastic cap.
  • the inventive design of the plastic cap thus allows a simplified and safer handling of the seal assembly even with one hand.

Abstract

L'invention concerne un agencement d'étanchéité pour un accouplement de conduites de fluide frigorigène constitué d'un premier élément d'accouplement connecté hermétiquement à un premier embout de conduite et un deuxième élément d'accouplement connecté hermétiquement à un deuxième embout de conduite. Une bague d'étanchéité est maintenue par un dispositif de maintien réalisé sous forme de capuchon en plastique avec un alésage traversant, contre la surface d'étanchéité de l'un des deux éléments d'accouplement. L'invention est caractérisée en ce que le capuchon en plastique présente à son extrémité axiale tournée vers l'un des éléments d'accouplement et opposée aux nez de retenue (6), au moins une saillie (7) tournée radialement vers l'intérieur, qui est réalisée de telle sorte que la bague d'étanchéité puisse être enclipsée dans le capuchon en plastique de telle sorte que la bague d'étanchéité soit maintenue dans l'état enclipsé entre les rainures de retenue (6) et la ou les saillies (7) dans le capuchon en plastique.
