Definitions

  • the present invention relates to the field of flow control of a fluid, preferably gaseous, specifically the regulation of the gas flow injected into the cylinders of an internal combustion engine.
  • the invention relates more particularly to a method of producing a support plate for valve body intended to be mounted between the cylinder head and the distributor or intake manifold of a motor vehicle, such a support plate comprising regulated duct portions. and portions of unregulated conduits.
  • Such a regulation makes it possible to obtain equivalent fluid speeds both at low and high engine speeds, by closing off the portions of ducts regulated by the valves during operation at low speeds and by allowing the passage of the fluid in the latter. as part of a larger plan.
  • Another problem lies in the lack of tightness between the distributor and the cylinder head.
  • the present invention proposes to overcome the disadvantages of known devices and to provide a support plate in which the alignment of the bearings of the control shaft carrying the valve bodies is kept in time.
  • a support plate could constitute a single piece of complete equipment that can be mounted between the engine cylinder head and the distributor or intake manifold easily and ensure tightness between them.
  • an intake manifold comprising an arrangement of flapper valves with two housings constituting passages communicating between the outlets of the manifolds and the inlets of the cylinder heads.
  • Each casing is of substantially planar structure and forms a support body for valves intended to regulate the gaseous flow passing through the manifolds of the intake manifold into the inlet openings of the cylinder head.
  • Each housing is constituted by at least one pair of regulated conduit portions having a valve body and forming a regulated flow passage and unregulated conduit portions having no valve body and an unregulated flow passage, said portions of regulated and unregulated conduits fluidly connecting, in the mounted state of said support plate, the manifolds of the intake manifold to the inlet ports of the cylinder head.

Under these conditions, the regulated duct portions 4 of the support plate 1 are aligned with the unregulated pipe portions 4 '.

  • the flanges 14 may be present in the number of two arranged face to face to each other at each portion of duct 4 'and made at the walls separating the portions of regulated ducts 4 and unregulated 4'. The shape of these flanges 14 and their positioning will be chosen so as to allow alignment of the through grooves 10 of the valve bodies 5 with the bearings 7 and 9.
  • the method according to the invention may consist in providing a base reinforcement 22 in which the assemblies 21 constituted by a controlled portion of duct 4 and a portion 19 or an unregulated portion of duct 4 'associated with said regulated portion 4 are separated by a separation wall projecting from the plane of the base armature 22, partition wall in which is formed a bearing 7 in the form of an orifice passing through said partition wall, this bearing constituting a bearing 7 for guiding the control shaft 8.

  • the Figure 2B represents the step of mounting the control shaft 8 which consists of introducing the latter through all the bearings 7, 8 and through grooves 10 of the valve bodies 5.
  • the control shaft 8 can be realized in steel or brass, for example. This insertion is carried out from a first end 6 of the base frame 22 which may comprise a guide bearing 7 made in the form of a hole passing through the circumferential wall 2 of said base frame 22 at a 6.

  • the support plate 1 thus also has a sealing function, in addition to its function of regulating the gas flow. It can also absorb the vibrations between the distributor and the cylinder head and limit the deformations due to these vibrations.
  • the support plate may have different shapes, particularly as regards the positioning of the unregulated pipe portions 4 'relative to the regulated pipe portions 4 which are aligned with the base plate 22

  • This form of the bearing surfaces 12 allows a correct operation of the valve bodies 5 via the control pin 8.
  • the spans 12 have a length less than the length of the through groove 10 of the valve bodies 5, but however greater than half the length of the latter. This makes it possible to obtain a correct drive of the valves with a minimum of overmoulded material.
  • the method may consist in producing each mounting key 13 by applying an extra thickness on a portion of the rod forming the control shaft 8, said portion having a length substantially equal to the depth of the corresponding bearing 7 and a diameter such that the mounting key 13 can be accommodated therein.
