ABSTRACT OF THE DISCLOSURE A paint spray gun of the hydraulically atomizing or airless type is disclosed. The spray nun includes a central passageway for delivering liquid paint under pressure to a spray tip having an elongated, sharp edged spray opening and a pre- orifice adjustable in cross-sectional area positioned co-axially upstream in the passageway from the spray opening. The cross- sectional area of the pre-orifice is adjustable by operation of control knob externally mounted on the body portion of the spray gun. In a first embodiment, the pre-orifice is defined by jaw members which are relatively movable by operation of the control knob. In a second embodiment, the pre-orifice is formed by an elastomeric member having an opening therethrough. The elastomeric member is arranged for axial loading and elastic deformation to vary the cross-sectional area of the pre-orifice opening by oper- ation of the control knob. -1-
