Definitions

  • the present invention relates to an injector device of a new type and its production method, this device being intended to inject under high pressure into the wood a treatment liquid.
  • One method consists in inoculating the liquid by a hollow needle which punctures a dowel previously placed in the wood and the recessed part of which has holes or slots to allow the liquid to pass through the wood.
  • This process is used less and less because the perforation created allows a return of the pressurized liquid to the outside.
  • Some injectors internally include a liquid non-return device.
  • valve or lip injectors do not provide a good seal
  • the ball injectors require two operations for their realization which are firstly the molding of the injector and secondly the installation of ball, which makes them more expensive.
  • the present invention allows these drawbacks to be completely eliminated.
  • the injector according to the invention may consist of a body (1) of molded material, of the polyamide or nylon type, intended to be pressed into a pilot hole in the wood to be treated, the end (2) being struck directly by a hammer, so that at the end of the driving operation, this end does not exceed the surface of the wood to be treated (3).
  • the outer part of the body includes annular projections (4) ensuring good anchoring of the injector.
  • the injector comprises a cavity (5) intended to receive an injection head (6) of spherical shape, this cavity being able to have a shape such that the spherical injection head (6) comes press on the circular edges (16) and (17) that the injector may have, which ensures a double seal at the time of injection.
  • the injection head (6) is held by pinching due to the elastic deformation of the flared part (8) of the body of the injector.
  • the central interior part of the injector comprises a hollow frusto-conical part (9) forming with a moving part (10, 11) a valve preventing the return of the liquid after the injection.
  • the movable part (10,11) is a part of revolution comprising a hollow cylindrical part (10) serving as a guide and a rounded or semi-spherical head (11) with a diameter greater than the diameter of the cylinder (10) and smaller than the diameter of the hollow cylindrical part (13) of the injector, and which can rest on a ring (12) in which hollow grooves (14) are arranged parallel to the axis of the injector, and intended to favor the passage of the liquid during the injection.
  • Figure 1 shows the device at the time of injection.
  • the injection head (6) is pressed into the cavity (5), the flat face of the head (11) is supported on the crown (12) and the pressurized liquid flows through the grooves (14) to spread in the part (13) of the injector and in the wood to be treated.
  • Figure 2 shows the device after injection.
  • the pressure existing in the treatment zone pushes the moving part (10, 11) until the head (11) is in contact with the hollow conical part (9), ensuring a perfect seal.
  • the injector is produced in a single molding operation.
  • the injector body is crossed by two pins (18) and (19), the pin (19) itself being traversed in its center by a sliding pin (21).
  • the position of the pins (18) and (19) is such that a zone (20) of less resistance occurs between the crown (12) and the part (10,11) during molding.
  • the spindle (18) is easily removed despite the cavity (5) and the undercut formed by the cone (9), thanks to the elastic deformation of the flared area (8) of the injector.
  • the spindle (21) then pushes the part (10, 11) which, thanks to the zone of reduced thickness (20) between the pins (18) and (19), is easily detached from the body of the injector and can be move freely inside of it.
  • the injector no longer exceeds the surface of the wood, thus avoiding an operation to cut flush with the surface of the wood the head of the injector, it allows subsequent injections to be carried out. provides an excellent seal and its cost is reduced thanks to a single molding operation to obtain the body and the moving part of the injector.
