Patent ID: 7708504

Claim:
A pneumatic nozzle comprising: a substantially linear conduit having a material inlet defined along one end of the conduit and an outlet defined on the opposite end of the conduit; a coupling attached to a side of the conduit, the coupling adapted for introducing a pressurized supply gas into a receiving chamber defined within an interior of the conduit, the receiving chamber having disposed therein a conical plug in which the outer wall is tapered toward the outlet, the conical plug further defining a bore therethrough, the bore being in axial alignment with the inlet and the outlet of the conduit; wherein when the supply gas is introduced through the coupling, the supply gas enters a cylindrical-shaped chamber and is directed along a gap defined between the outer wall of the conical plug and an interior nozzle wall toward the outlet, the flow of the supply gas creating a negative pressure at the inlet which may be used to introduce a material into the interior of the nozzle, where the supply gas pushes the material toward an outlet of the nozzle.
