Orbital applicator tool with static mixer tip seal valve

摘要

An applicator dispenses a pressurized fluid to a workpiece to be processed with an elongate housing having a first end and a second end. An enlarged annular flange extends radially from adjacent the first end of the housing and is connectable to a source of pressurized fluid. A tapered cone is formed on the second end to define a reduced diameter relative to the housing to enable streaming of the pressurized fluid to be applied. A separate mixer is positionable within the housing. Preferably, the mixer is moveable longitudinally with respect to the housing during use. The mixer includes a valve member connected to one end for movement relative to a valve seat defined by an inner surface of the cone. The valve member moveable between an opened position and a closed position. A piston is connected to an opposite end of the mixer from the cone to move the mixer longitudinally within the housing. The piston is moveable within a chamber between first and second end limits of movement.
