Definitions

  • a hose gun as defined in claim 1 of the appended claims.
  • a hose gun according to this aspect minimizes the problem of dripping or leaking when the pressure of fluid supplied thereto is low or cut off. This is achieved by the combination of the claimed stem and body being arranged such that the stem can act on the body so as to close both the flow paths, and also by providing spring means that biases the body to act in this way.
  • the gun may be arranged so that operation of the user control causes axial movement of the stem and/or body within the gun.
  • the end of the actuator carrying the bearing surface may pass through a side wall of the cage and into a slot in the stem. This arrangement can help to prevent rotation of the stem relative to the remainder of the gun and/or relative rotation of the stem and body during normal use and can therefore help to keep the stem and body in the desired relative orientations.
  • the base plate may comprise a plurality of apertures, each aperture corresponding to an outlet end of a respective fluid flow channel.
  • At least some of the function outlets comprise a respective aperture in the base plate.
  • the cover plate may comprise a plurality of apertures, each aperture corresponding to an inlet end of a respective fluid flow channel.
  • Figure 1 is a side view of a hose gun
  • Figure 2 is a plan view of the hose gun shown in Figure 1;
  • Figure 6 is a front view of a hose gun including a first alternative head
  • the valve arrangement 5 provides two stage valve opening. This is achieved by providing two separate fluid flow paths through the valve arrangement 5 (see Figures 8 and 9).
  • a first valve is provided by the extreme end of the head 53 having a shoulder 59 carrying an O- ring seal which can act against a seat 510 provided by the body 52.
  • the second valve is provided by the extreme end of the body 52 having a shoulder 511 carrying an O-ring seal which can act against a seat 512 provided in the bore 6 of the gun body 1.
  • the two abutment projections 41, 42 are behind the abutment surface 83 and so do not affect the position of the trigger 4.
  • the static portion 31 of the head acts as a link between the rotatable portion of the head 32 and the remainder of the body of the gun 1.
  • the static portion 31 comprises a fluid communication channel 33 which provides a fluid flow path to a supply outlet 34 from which inlets 101 of the directing portion 10 may be supplied with fluid.
  • the directing portion comprises a plurality of inlets 101 which may be selectively presented to the supply outlet 34.
  • the supply outlet 34 is offset from the rotational axis of the rotatable portion 32 of the head 3. Therefore as the directing portion 10 is rotated as part of the rotatable portion of the head 32 the different directing portion inlets 101 are presented to the supply outlet 34.
  • cover plate 120 for the six function head six inlet apertures 101 are provided and there is a blanking portion 102 in place of the seventh aperture.
  • the cover plate 120 is welded onto the base plate 110 such that the blanking portion lines up with the channel which is used to supply fluid to the perlator in the seven function head.

Abstract

L'invention a trait à un pistolet d'arrosage, qui comprend un corps principal (1) dans lequel est placé un agencement de vanne (5). L'agencement de vanne (5) est situé dans un alésage du pistolet qui sert de conduit de fluide entre l'orifice d'admission de fluide (2) du pistolet et un orifice de sortie de fluide du pistolet. L'agencement de vanne (5) comprend une partie tige (51) et une partie corps (52), la partie tige (51) possédant une tête (53) qui est capturée dans un logement formé par la partie corps (52). La partie tige (51) et la partie corps (52) peuvent se déplacer l'une par rapport à l'autre pour former une première vanne ; et la partie corps (52) peut se déplacer par rapport à une structure adjacente du pistolet qui définit au moins une partie de l'alésage pour former une seconde vanne. Une gâchette (4) pouvant être actionnée par un utilisateur peut déplacer la partie tige (51) pour que cette dernière ouvre la première vanne, puis continuer à déplacer la partie tige (51) pour que cette dernière bute contre la partie corps (52) et ouvre ainsi la seconde vanne. Le pistolet selon l'invention comprend également un ressort (55) qui agit sur la partie corps (52) de sorte que, lorsque la gâchette (4) est libérée, la partie tige (51) soit poussée contre la partie corps de façon à fermer à la fois la première vanne et la seconde vanne.
