Definitions

  • the present invention relates to the field of controlling the flow of fluids, in particular gaseous fluids, and more particularly in the context of the air intake for heat engines, for example in connection with the intake manifolds, but also more generally, flow control devices in a passage by means of a member disposed in this passage and manipulated by a control shaft.
  • the present invention more specifically relates to a device for regulating the flow in a conduit portion or a passage, an intake manifold comprising such a device and a method of manufacturing such a collector.
  • a device for regulating or controlling the flow or flow in a passage of a portion of conduit or the like generally takes place, during one or more particular operations, either by mounting a transverse insert carrying the adjusting member in said pipe portion, after cutting an opening in the latter, or by setting up an intermediate pipe segment provided with said adjustment member between two spaced apart portions of said portion of conduit.
  • US-A-5,813,380 shows an intake manifold according to the preamble of claim 1.
  • the regulating device is mounted via the additional bearing structures pre-mounted on the control shaft of the regulating device and fixed in a portion forming portion of the manifold intake manifolds.
  • the present invention is intended to overcome at least some of these disadvantages.
  • FIG. 1 The figures of the accompanying drawings show a device for regulating the flow of a fluid, in particular gaseous fluid, in at least a portion of duct 2, a passage, an opening or the like (for example a portion of any fluid circulation circuit ) by means of a valve 3 or a similar rotary shutter member carried by a control shaft 4.
  • each valve assembly 3 / control axis 4 is integrated in the structure of the portion of conduit 2 concerned or in the structure of the part 1 comprising at least a portion of conduit 2, at an opening passageway being trapped, with rotational capability, between two complementary parts 2 ', 2 "or 1", 1 "' forming by assembly said conduit portion 2 or said part 1 and being mounted in receiving recesses 5, 5 'corresponding formed in the walls of the portions of conduits 2 and / or in one or bearings (s) or separate (s) corresponding 6 present (s) on at least one of the parts 1 ", 1" 'forming part 1.
  • the invention applies both to a portion of duct 2 or to a single passage opening, to several portions of ducts 2 or openings connected or not to each other and disposed between them in any manner.
  • the regulating device may comprise a set of valves 3 / axis 4 extending to several portions of ducts 2 or passage openings of the part 1 each comprising a valve 3, all these valves 3 being mounted or formed on a single control axis 4.
  • conduit portion is meant herein any circular passage or not that can be closed by a movable member valve type. This passage may, where appropriate, be reduced to a simple through opening or passage opening, the axial or longitudinal dimension of the conduit portion 2 then being very reduced, or even zero.
  • the assembling or connecting lines 2 "' resulting from the intimate contacting of the connection between the joining or joining surfaces of the two constituent parts 2' and 3, may be located in a perpendicular plane to the axis of the duct portion 2 concerned, but also extend in other directions to facilitate the assembly of parts 2 'and 2 ".
  • control pin 4 is attached at one of the ends of the duct 2, being attached to wall portions (connecting for example two adjacent ducts) in staggered locations with respect to the duct wall.
  • the support of the control shaft 4 and its rotational guidance can be provided, at least in part, by at least one bearing 6 outside the wall or walls of the portion (s) of conduit (s) 2 or of the part 1 considered (s), if appropriate formed by assembling two complementary parts each on the one of the parts 1 "and 1" 'or preformed exclusively on one of the two aforementioned parts.
  • said control shaft 4 may comprise one or more cylindrical protrusions 9 or annular (disc) 9 ', formed of a alone holding with said axis 4 or reported on the latter by overmolding or mounting, and intended to cooperate with the support and guide bearings 6, 7 or with stops 10 for locking in translation of said control shaft 4.
  • the protuberances 9, 9 ' may advantageously consist of a material resistant to wear and / or having a reduced coefficient of friction with the material constituting the support and guide bearings 6 and 7, the annular protuberances 9 in the form of sleeves can present discoidal stops 9 "at their opposite longitudinal ends so as to form locking sites in translation for the axis 4 after mounting.

  • the two parts 2 'and 2 "or 1" and 1 "' constituting the conduit portion 2 and / or the part 1 are made of thermoplastic material and are assembled by vibration welding, the planes of the seal being configured and arranged in such a way that they allow, if necessary, the installation of the control pin 4 / valve 3 on or in one at least of said two parts or between them.
  • Sealing at the passages of the axis 4 may be obtained by forming a seal at the time of assembly, by a separate sealing element reported before or after assembly or by reporting an additional part or part 17 by vibration welding at the outer face of the passage (s) concerned (s), this additional portion may, where appropriate, contain a support bearing and guide 6, 12 axially sealed.
  • the passage 15 ' is first formed during the assembly of the parts 1 "and 1"' by superposition at the portions of their respective opposed weld seams 19 'and 19 "(FIGS. 8A and 8B), so as to obtain a cross-sealed passage 15 'whose external opening opening is surrounded (on the outer face of the workpiece 1) with two portions of semicircular cords (FIG. 8C) forming together a circular bead surrounding said opening.
  • the circular bead 19 "'coinciding with a sealing piece 17 is then applied to the two semicircular cords 19' and 19" and their assembly is made by vibration welding (FIG. 8D: side elevation view) to obtain a set of parts 1 and 17 waterproof.
