An improved reversible airless spray tip inhibits dripping, spitting, and undesirable paint accumulation on the spray guard, while improving safety. A positioning detent on the spray tip carrier handle snaps positively into place when a nozzle carrier is rotated into spray position, indicating that the tip is properly positioned for spraying. A spray guard with airfoil-like cross-members protects the user from injury while they inhibit turbulence and prevent paint accumulation. An improved piston seal has a slot-like fluid passage, which is preferably substantially rectangular in cross section. A rearward end of the piston seal is sealed by a resilient ring compressed directly against the face of an attached spray gun. An improved tip retainer is expanded by swaging after insertion, which forces a lip into a mating slot. The tip retainer also has an expanded chamber which diffuses reverse fluid flow for safety.

[ We claim:] [1.]1. An improved reversible spray tip for use with airless paint spraying equipment to project a spray pattern, and mountable on a pressurized paint sprayer, comprising:a nozzle carrier, rotatable about an axis, and having a fluid passage and a spray nozzle in said fluid passage;a cam which co-rotates with said rotatable nozzle carrier, said cam having a position stop; anda counterstop disposed to engage said position stop when said nozzle carrier is rotated to a predetermined rotational position, so that rotation of said nozzle carrier from said given rotational position is bi-directionally resisted;wherein said position stop comprises a projecting detent for resisting rotation of said rotatable nozzle carrier.
