Abstract:
1. A reversible airless spray tip assembly comprising: a cap having a first radial bore; a rotatable cylinder disposed within the first radial bore, the rotatable cylinder having a first axial bore therethrough and a shoulder projecting into the first axial bore; a spray tip having a tip, an annular projection, and a spray orifice, the spray tip disposed within the first axial bore with the annular projection abutting the shoulder; a sleeve having a second axial bore therethrough, the sleeve disposed within the first axial bore upstream of and abutting the spray tip, with the second axial bore aligned with the spray orifice; a shutoff mechanism disposed within the cap upstream of the rotatable cylinder, the shutoff mechanism comprising: a dead zone defined by the second axial bore, the third axial bore, and the fourth axial bore; and wherein compressible materials are eliminated from the dead zone such that spitting of fluid from the dead zone is minimized when the reversible airless spray tip is shut off.
