Patent ID: 7007867

Claim:
In an apparatus for dispensing treatment material including a material source, a pump mechanism to move said material through a passageway to a defined apparatus outlet, and a nozzle assembly including a nozzle element for directing a flow of said treatment material from said source and along a nozzle axis to said outlet, the improvement comprising: an inner nozzle element having an inward and an outward end, both communicating with said passageway; said inner nozzle element arranged generally along said nozzle axis and defining a chamber at said outward end thereof; said chamber adapted to re-direct said treatment material flow along a path outwardly from said nozzle axis toward a location at said outer end for communication with said defined apparatus outlet; said apparatus outlet is formed as at least one defined outlet orifice, said at least one outlet orifice shaped and adapted to redirect said treatment material from said location and along a path at an acute angle relative to said nozzle axis; whereby treatment material drawn by said pump from said supply is forced through said passageway and through said chamber outwardly from said nozzle axis, and redirected subsequently through said at least one outlet orifice at said acute angle so as to exit said apparatus at an angle to said nozzle axis.
