ABSTRACT:
There is disclosed a spray nozzle head for spraying of pressured liquid such as airless spraying and the like which is constructed with a minimal number of parts and which provides for facile reversal of the spray orifice in the head, thereby permitting the orifice to be cleaned by the liquid pressure. The spray nozzle comprises a body with a longitudinal through passageway and a cylindrical through bore orthogonal to and intersecting the through passageway. A cylindrical turret member which carries a removable orifice spray tip is seated in the through bore and is restrained therein by a detent which permits rotation of the turret member through at least 180.degree. for reversing the direction of the orifice spray tip. The turret member is sealed by a single seal washer that is biased against the turret member by an adaptor threaded into an internally threaded counterbore in the longitudinal through passageway of the body. The body is turned to advance the adaptor against the seal washer biasing the latter against the turret member, sealing the latter and permitting discharge of the liquid through the orifice tip. When the orifice tip becomes clogged, the turret member is released for rotation by twisting the body on the adaptor, releasing the tension on the seal washer and permitting the turret member to be rotated 180.degree. by finger pressure. In another embodiment, the necessity for twisting of the body on the adaptor is eliminated by providing a hand lever on the turret member whereby the turret member can be rotated against the biasing force of the adaptor.
