Definitions

  • the present invention relates generally to variable pressure vessels and more specifically condensers of heat exchangers in an air conditioning installation of a motor vehicle.
  • Containers of this kind include, among other things, a cartridge exchangeable filled with desiccant granules.
  • This cartridge is introduced into a tubular element defining an opening of the container outward.
  • This opening can be closed using a cap fitted with O-rings and which can be inserted by sliding in the tubular element. Moving the plug to the interior is limited by a stop means in the form of a shoulder circular on the inner surface of the tubular member.
  • detachable axial stop means can be put in place inside the tubular member to limit movement of the plug outwards.
  • FR-2 798 456 a container in the form of a collector for a condenser of an air conditioning system.
  • This manifold has a tubular element closed by a plug cylindrical whose movement towards the outside is prevented by axial stop means constituted by a circlip in the form of a ring split elastic.
  • this circlip When the plug is in place in the tubular element, this circlip is introduced through the open end of the tubular element and placed in a circular groove provided on the inside of the element tubular, near the end of it.
  • the cap has at its end directed towards the circlip a circular peripheral recess adapted to the shape of the circlip in order to be able to receive it when the cap is pushed outward by an overpressure prevailing in the container.
  • the implementation circlip position is a relatively delicate operation which takes a certain time and which requires a specialized tool.
  • the machining of the inner face of the tubular element to prepare the circular groove serving as a retaining ring is an operation which increases costs of the assembly.
  • the object of the invention is to remedy these drawbacks by proposing a container of the kind mentioned provided with stop means axial of the cap towards the outside which are also extremely simple both in use and in manufacturing, while ensuring safety operators.
  • the object of the invention is a variable pressure container connected to a tubular element delimiting an opening of the container towards the outside, said opening being capable of being closed by a plug provided sealing means and adapted to be introduced by sliding axial in said tubular element, said plug being associated with detachable axial stop means capable of cooperating with axial locking means provided in said tubular element and allowing said stop means to extend transversely in this in front of the outer end of said plug to prevent removal thereof when an overpressure prevails in the container, characterized by the fact that said means for axially locking said means abutment have a first slot in the wall of the element tubular and a second slot diametrically opposite to said first slot, and that said stop means are adapted to be introduced transversely into said tubular element by said first slot and to protrude outside said tubular element by said second slot.
  • the container can be a heat exchanger condenser or any other container under variable pressure. In the case of the condenser, this pressure can drop to atmospheric pressure when the installation of which the condenser is part is not in operation.
  • This container which is known per se will not be described in detail; he is in the figures materialized by a tubular element 1 connected to the container and delimiting an opening 2 of the container towards the outside.
  • the opening 2 is closed by a plug 3 having generally the shape of a cylindrical piston which is introduced by axial sliding in the tubular element 1.
  • This plug is preferably made of aluminum and includes sealing means comprising in the example illustrated two circular grooves 4 serving as housings with two O-rings 5.
  • the tubular element 1 has on its inner face a circular shoulder 6 constituting a stop member delimiting the displacement of the plug 3 inwards.
  • axial stop When the plug 3 is in place in the tubular element 1 (see figure 2) and that it is pushed outwards by an overpressure that prevails inside the container, its movement is limited by means of axial stop (see figure 1).
  • axial stop means include a plate 7 which is illustrated as a whole in FIGS. 4 and 5. In the position of Figure 1, the large lower surface of the plate constitutes a stop surface for the plug.
  • This plate 7 which is preferably made of steel, is introduced transversely in the tubular element 1 by a first slot 8 of the wall thereof to protrude outside the tubular member by a second slot 9 diametrically opposite the first slot.
  • the first and second slots 8, 9 constitute means for axial blocking of the plate when it is in the position illustrated in Figures 1 and 2.
  • the rod has a T-shape as shown in the figures.
  • the hole central 10 of the plate 7 has an elongated shape allowing introducing the end of the rod through this hole when the cap is pushed up by overpressure, whereupon the cap can be rotated about 90 ° to prevent it from coming back down when the pressure drops.
  • the rod preferably has on the transverse element 12 of its T-shape two parallel lateral 13 flats allowing the grip by a tool to rotate the plug 3.
  • this shape of the rod offers excellent grip for later removal of the cap outside the tubular element 1.
  • the same stop function for the plate when it is placement can be obtained by an increased width of the part rear of plate 7 which then has shoulders abutting against the outer surface of the tubular element 1.
  • the front end of the plate is preferably beveled.
  • Figure 9 illustrates a variant of the plate 7 in which the ends of the plate have a raised rim 16 constituting a transverse locking means of the plate when the plug 3 bears against the abutment surface of the plate.
  • the slots 8, 9 in this case have a greater width compared to that illustrated in FIGS. 1 and 2 in order to allow the introduction of the plate.
  • the plate with a raised rim end can easily be manufactured in a stamping and punching.
  • the means according to the invention operate from the following way from a situation in which the plug 3 and the plate 7 are dissociated from the tubular element 1 of the container.
  • the plug 3 is introduced by axial sliding in tubular element 1 until it abuts against the shoulder circular 6 on the inner surface of the tubular element. Then the plate 7 is introduced through the slots 8, 9 of the tubular element until its shoulders 14 abut against the surface inside of the tubular element.
  • the rod is a circular rod, the device is already in principle ready for operation.
  • the stem 11 of the plug has the T shape, it is important to ensure that it is during the introduction of the cap oriented as shown in Figure 2 to allow the subsequent passage of the rod through the central hole 10 of the plate. Then, increase the pressure in the container so that the plug 3 is pushed outwards, which has the result that it abuts against the plate 7 and that the rod does the same time protruding through the central hole of the plate. Then just turn the stopper of about 90 ° to prevent it from coming down again when of depression.
  • Disassembly of the assembly is done in reverse order. First, it the pressure must have dropped significantly to be practically equal to atmospheric pressure. Then start by turning the cap about 90 ° in the case of a rod in T. The plug is then moved inward by pushing on the rod and that enough so that it is completely free of central hole 10 in plate 7. Then plate 7 can be removed from the tubular member to allow removal of the plug, giving finally access to the interior of the tubular element.
