  • Fig. 2 is a separate rotary union with additional outer seal.
  • a preferred embodiment of a rotary union 10 for use together with a quick connector 1 is shown, which is coupled to a connection nipple 30 indicated here on the left.
  • the quick-connect coupling 1 has a tubular housing 11 with a plurality of housing parts 11 ', 11 "and 11'" which are screwed together, the right front end serving as inlet 12 and the left front end serving as outlet 13 for the forwarding of the fluid to be transmitted to the connection nipple 30.
  • the inlet area 12 to the housing 11 has a connection adapter 14 which is screwed onto the right housing part 11 ′ and is sealed via seals 24a against a rotating sleeve 24 of a rotating union 10.
  • the rotating sleeve 24 has at its right end a thread 24b to which a fluid line 12 'for supplying the fluid to be transferred can be connected.
  • the connection adapter 14 with the inserted rotary sleeve 24 can be designed accordingly in adaptation to the fluid to be transferred, in particular to the respectively desired supply pressure values, passage cross sections, etc.
  • connection adapter 14 On the outlet 13 opposite the connection adapter 14, a plurality of elongated collets 15 arranged in tubular form are provided.
  • the collets 15 are at their right end here suspended on an annular groove 11a of the housing part 11 " # and thereby pretensioned by an annular spring 16, so that the collets 15 can be expanded radially outwards Connection profile of the connection nipple 30 formed positive engagement profiles 17.
  • a sealing piston 22 is guided on the inner circumferential surface of the housing part 11 "toward the outlet 13, which has a conical sealing surface 23 on its front end face for contact with a sealing ring of the connecting nipple 30, so that the essentially gaseous and / or liquid fluid flowing along the central axis of the quick coupling 1 cannot escape to the outside.
  • an outlet valve 25 is provided on the sealing piston 22, which seals against the sealing piston 22 in the closed position by means of a sealing ring as a valve seat 26.
  • This outlet valve 25 is acted upon by a compression spring 28 which is guided by means of an insert 27.
  • an annular piston 29 Opposite the outlet valve 25 there is an annular piston 29 which cooperates with the insert 27 when the quick connector 1 is uncoupled from the connecting nipple 30, the latter being displaced along the connecting nipple axis during uncoupling and together with a gradation of the insert 27 forms a vent valve 35.
  • the vent valve 35 is actuated by pivoting the control lever 50, since the eccentric shaft 51 engages in the annular piston 29.
  • the sliding sleeve 18 By actuating (pivoting by approximately 180 °) the control lever 50 into the position shown here, the sliding sleeve 18 is pushed over the collets 15 and thus locked.

  • the inlet valve 45 is also axially displaceable by the control lever 50 and its eccentric shaft 51 by the engagement in the annular piston 29.
  • the annular piston 29 displaces a valve slide 47 into the open position, so that the fluid flowing in from the inlet area 12 can flow around a flow body surrounding the valve slide 47 to the outlet end 13.
  • At least one passage 24c to a pressure equalization space 44 is provided within the rotary leadthrough 10 with rotary sleeve 24, which is preferably integrated in the quick connection coupling 1.
  • the passage 24c is preferably designed as a radial bore, while the pressure compensation space 44 is designed as a shoulder-like collar between a gradation in this regard on the rotary sleeve 24 and the connection adapter 14.
  • the pressure compensation chamber 44 is sealed by the two seals 24a.
  • the pressure compensation space 44 has along its annular shoulder the same effective annular area as the end face 43 of the rotating sleeve 24.
  • the rotating sleeve 24 is free of axial force at every pressure value.
  • the axial bearings 48 required for axially fixing the rotary sleeve 24 are not pressed, it being possible for one of the axial bearing disks 48 to be arranged in the pressure compensation space 44 in a preferred manner.
  • the vent valve 35 is opened by the eccentric shaft 51 and the annular piston 29.
  • pressure medium still present flows via an annular space 36 to a ventilation hole 37 which runs parallel to the central fluid passage (through the valves 45, 35 and 25) along the housing part 11 'of the rotary union 10.

  • the cover 39 is connected to the rotating sleeve 24 with a transverse pin 40 (or transverse screw).
  • the annular space 38 is sealed off from the housing 11 or the connection adapter 14 by means of two ring seals 41.
  • a gas return line is connected as a second line 42 to the cover 39 which rotates with the rotating sleeve 24 and the adjacent stationary housing part 11 'of the rotary union 10, so that the gas return line 42 and the fluid line 12' connected to the thread 24b are always at least largely run parallel to each other and therefore cannot twist.
  • the rotary feedthrough 10 integrated in FIG. 1 can also be designed as a separate component, in particular as a retrofit part for existing couplings.

Abstract

Pour simplifier la structure d'un passage tournant pour transporter des fluides gazeux et/ou liquides, notamment pour remplir le réservoir des gaz d'un véhicule, avec une partie de boîtier et un manchon tournant (24) monté de manière à pouvoir tourner par rapport à la précédente, qui est relié à une première conduite fluidique (12') et comporte au moins un passage (24c) vers une chambre de compensation de la pression (44), il est prévu qu'une seconde conduite (42) orientée dans une large mesure parallèlement au manchon tournant (24) soit raccordée sur la partie de boîtier (11') dudit passage tournant (10).
