Abstract
A spray tip assembly capable of self-clearing is provided. The spray tip assembly includes a distal end including an outlet. The outlet defines at least a first configuration during a first condition and at least a second configuration during a second condition. The distal end may be configured to at least one of flex and expand such that the outlet changes from the first configuration to the second configuration.
Claims17
A spray tip assembly comprising:
- an elongated body defining a longitudinal axis;
- a distal end including an outlet formed about the longitudinal axis of the elongated body and having a substantially circular cross-section, the distal end defining at least a first configuration during an at rest first condition and at least a second configuration during a second condition, wherein the outlet is open in both the first and second configurations;
- and
- a mixing portion configured for mixing at least a first component and a second component.
1 more element
A self-clearing applicator comprising:
- an elongated body defining a longitudinal axis;
- a spray tip assembly operably connected to a distal end of the elongated body and having a distal end including an outlet defining an axis that is coaxial with the longitudinal axis of the elongated body, the outlet defining at least a first open configuration at rest and during normal operation and at least a second open configuration when the outlet is at least partially obstructed, wherein a distal surface of the distal end defines a recess about the outlet;
- and
- a mixing portion configured for mixing at least a first component and a second component.
1 more element
A self-clearing applicator comprising:
- a spray tip assembly including an outlet having an open configuration at rest, wherein the outlet includes a first cylindrical portion, a second cylindrical portion and a recessed portion, each of the first cylindrical portion, the second cylindrical portion and the recessed portion being deformable to permit clearing of an obstruction from within the outlet;
- and
- a mixing portion configured for mixing at least a first component and a second component.
A self-clearing applicator comprising:
- a spray tip assembly including a mixing portion and defining an outlet, the spray tip assembly capable of undergoing a change in cross-sectional geometry from a first configuration, at rest and during normal use, wherein the outlet includes a first diameter, to a second configuration wherein the outlet includes a second diameter to clear an obstruction from the outlet, the mixing portion includes at least a first radially inward extending slot for directing a partially mixed solution towards the outlet.
