A reversible, multiple spray tip spray gun tip assembly includes a tip holder and a turret. In one embodiment, the tip holder has a turret opening and a fluid spray passage that is in communication with the turret opening. The turret has a barrel including a plurality of spaced apart spray tips and a handle to rotate the barrel within the turret opening. Either the tip holder or the turret includes one or more projections while the other of the tip holder or the turret includes a cam surface with which the one or more projections slideable engage such that rotating the turret relative to the tip holder causes the turret to translate relative to the tip holder and to align each of the spray tips with the fluid spray passage in a spray position and a clear position.

Multiple spray tip turret assembly for paint sprayer

A self-contained, hand-held paint spray gun apparatus having a paint reservoir on the gun and a turret assembly having a reversible tip for spraying paint from the reservoir through the tip and a swirl chamber adapter located between the gun and turret assembly. The tip is reversible between a SPRAY position and a CLEAN position to enable a user of the paint spray gun to rapidly and conveniently clear an obstruction in the tip and continue spraying without removing the tip. The swirl chamber adapter has a generally planar face opposing a swirl valve in the gun and forming a swirl chamber upstream of the turret assembly and has a centrally located bore extending from the generally planar face to the outlet of the adapter.

A collapsible cart for paint sprayers including a pair of spaced apart legs, a pump support extending between the upper ends of the legs, a pair of feet, a handle extending above the pump support, and lock and release means connected to the handle, pump support and legs and operable for releasably locking the pump support and handle in a first position wherein the pump support positions the pump for operation and the handle is positioned to enable moving the cart assembly and wherein the lock and release means is further operable for releasably locking the pump support and handle in a second position wherein the cart assembly is collapsed and further wherein each foot is pivotable respect to the leg to which it is attached between a first position generally perpendicular to a lower frame member, and a second position generally adjacent to the lower frame member.

An airless spray paint gun having an improved swirl valve which is less susceptible to erosion and reduces the amount of sputtering in the paint spray. The spray paint gun includes a gun assembly including a handle, a motor, and a switch for controlling the motor. A pump subassembly mounted to the gun assembly includes a pumping chamber having a discharge end with a beveled seat, a piston mounted within a pump housing and driven by the motor for pumping paint from the container through the discharge end of the pumping chamber, and a swirl valve mounted within the discharge end of the pumping housing. The swirl valve includes a valve body having first and second opposite sides, three paint swirl apertures extending through the valve body between the first and second opposite sides, an annular flange that radially projects from the valve body between the first and second sides, and a beveled seat-engaging surface on the second side of the valve body having an elastomeric material thereon co-molded with the valve body. The elastomeric material is softer than the material of the valve body. The flange is interposed between a spray tip and the discharge end of the pumping chamber and contacts the discharge end when the spray tip is mounted to the pump housing. The flange thus prevents excessive axial forces from being applied to the swirl valve, and thereby prevents cold flow and the plastic deformation of the elastomeric material while allowing the elastic deformation of the elastomeric material on the swirl valve. The elastomeric material is relieved in a cavity surrounding each swirl aperture to prevent migration of the elastomeric material into the swirl apertures.

Turbine unit

A housing for a fan motor for a portable paint spray gun has a compartment accessible from the bottom in which an air hose is storable and provides an air path from the fan motor to the air hose having a minimum number of turns or curves between the motor exhaust port and the air hose. The housing enhances portability by providing convenient storage for the air hose when not in use and increases fan motor efficiency by reducing drag on the air flow by providing a relatively low resistance air path from the fan motor to the air hose.

An improved pneumatic actuator for an electrical switch having a flexible diaphragm operating through a rigid disk member actuates an electrical contact when air pressure is applied to the diaphragm. A cylindrical ring acts as a guide for the rigid disk member. The rigid disk member serves to flatten the membrane and resist permanent deformation when air pressure is released from the membrane.

Air actuated switch for painting system

A self-contained power painting system is provided in which a battery operated motor and pump are contained in a lid for a paint reservoir, and that entire unit is adapted to be carried on a user by a strap or belt. A paint applicator, such as a brush or roller, is connected to the pump by a flexible conduit and includes a switch activator at the applicator to permit the user to selectively control operation of the pump and to move about freely while painting without being emcumbered by a relatively immobile paint reservoir or power source connection through extension cords.
