Orbital applicator tool with static mixer tip seal valve

An applicator for dispensing a pressurized fluid to a workpiece to be processed comprising:

• an elongate housing having a first end and a second end;
• a separate mixer positionable within the housing, the mixer moveable longitudinally with respect to the housing;
• a static mixer positionable within the housing, the mixer moveable longitudinally between first and second positions with respect to the housing, such that fluid flow is blocked in response to the static mixer being in the second position while permitting fluid to flow when the mixer is spaced from the second position;
• a cone defining a valve seat along an inner surface adjacent the second end of the housing;
• a valve member connected to an end of the moveable mixer for movement relative to the valve seat between an opened position and a closed position;
• and
• a piston connected to an end of the mixer opposite from the cone of the housing to move the mixer longitudinally within the housing, the piston moveable within a chamber between first and second end limits of movement.

An applicator for dispensing a pressurized fluid to a workpiece to be processed comprising:

• an elongate housing having an enlarged end and a constricted end;
• a static mixer positionable within the housing, the mixer moveable longitudinally between first and second positions with respect to the housing, such that fluid flow is blocked in response to the static mixer being in the second position while permitting fluid to flow when the mixer is spaced from the second position;
• and
• a piston connected to an end of the mixer opposite from the constricted end of the housing to move the mixer longitudinally within the housing.
