Abstract
The present invention relates to a low-cost, disposable spray tip for airless spraying, which has an orifice tip holder that is reversible between spraying and cleaning positions. The orifice tip is mounted in a rotatable turret member which is sealed in the assembly by a piston which is held against the rotatable member by a retainer threadably engaged in the body. The retainer is provided with a through running bore, portion of which is counter bored to receive the body of the sealing piston which is preferably retained therein by resilient annular sealing members. The body and spray guard are formed as a single piece, preferably by die casting or molding, and the through running passage and orthogonal bore are formed concurrently during the molding of die casting operation. The only additional components to be assembled are the retainer and the piston seal assembly and the rotatable turret member and the hand assembly. The spray tip assembly is retained on the spray gun by a retained nut which is loosely secured to the body of the spray tip by a shoulder formed by an enlarged head portion on the retainer which acts against a annular flange at one end of the retainer nut.
