ABSTRACT:
There is disclosed an improved spray tip for airless spraying of liquids in which the spray orifice is mounted in a rotatable turret member which is captured in a subassembly of a plastic spray guard and a tubular metal housing. The housing has a longitudinal through passageway which receives a floating piston seal member that has a forward, cylindrically concave face which is urged into a tight seal against the rotatable turret member by the liquid pressure which acts on the upstream face of the floating piston seal member. The floating piston seal member is sealed in the longitudinal through passageway by an annular seal which also restrains the turret member against rotation when the liquid pressure is released, thereby freely permitting substitution of spray orifices by interchanging of turret members. The turret member includes a handle with a dependent prong which is received through a slotted aperture of the spray guard into an internal cavity of the spray guard body having one side wall with shoulders which provide abutment stops for the turret member, thereby aligning its transverse bore with the longitudinal passageway through the housing.
