    Abstract: An apparatus for applying a foamable fluid plastic material including reactant fluids that form a foam when heated and mixed. A reactant fluid dispenser supplies the reactant fluids to a heated applicator gun mixing chamber at a constant flow rate despite any differences in viscosity. A valve needle extends into the mixing chamber and exposes fluid inlet openings when retracted, permitting the reactant fluids to flow into the mixing chamber. When advanced, the needle closes off the fluid inlet openings and dispenses the mixed fluids. A heater prevents the gun from drawing heat energy from initial quantities of the pre-heated reactant fluids which would prevent initial quantities of the fluids from reacting properly. The valve needle is disposed in a sleeve that defines the mixing chamber and is disposed in a sleeve receptacle of the gun.

To clear such blockages and restore the nozzle to operation, a grooved piston forming part of the nozzle orifice is retracted from its seated position within the nozzle barrel. Once the piston is retracted, the barrel opens to its full diameter allowing lodged particles to be flushed away. Several nozzles mounted in tandem upon a fluid distribution pipe form part of a header system which can deliver, in the form of spray, large liquid volumes. The header system allows the self-cleaning function of several nozzles to be efficiently controlled by a single apparatus.

  • Patent number: 4957239
    Abstract: A spray head for a fluid dispenser comprises a connecting duct for sealingly receiving a delivery tube stub of an aerosol valve; a spray orifice; a chamber connecting the connecting duct and the orifice; a piston member disposed in the chamber and presenting a needle member cooperating with the orifice; and a spring urging the piston member to the orifice. The orifice is sealed by the end of the needle member in an inoperative position, and the piston member is arranged to move against the force exerted by the spring under the influence of an elevated pressure prevailing in the chamber, whereby the orifice is cleared by the needle member. To provide for improved atomization, according to the invention, the rear face of the piston member, which faces away from the needle member, defines a closed space which through a channel is in communication with a point located near the spray orifice for the injection of air from the closed space into the product stream to be sprayed through the spray orifice.
