    Abstract: A gun-like spray device having a spray nozzle assembly at the discharge end and a reciprocatably movable valve needle for controlling the liquid flow through the discharge nozzle assembly. The nozzle assembly includes an orifice member which defines a liquid discharge orifice and a rigid valve seat for centering and precisely locating the valve needle in a closed position. An annular resilient sealing member is secured within the orifice member for engaging and creating a liquid seal about the valve needle separate and apart from the rigid seat when the valve needle is in a closed position. The spray nozzle assembly may be used with spray devices having different sized valve needles and includes a first rigid valve seat downstream of the resilient sealing member for receiving a relatively small diameter valve needle and a second rigid valve seat upstream of the resilient sealing member for receiving a relatively large diameter valve needle.

    Abstract: A liquid spray module which can be individually used, or which can be easily mounted in ganged side-by-side relation with a plurality of such modules. Each module includes a spray gun cartridge having liquid passages through the liquid to be sprayed, is directed and one or more air passages through which pressurized air may be directed for assisting in atomization of the liquid and controlling operating movement of a valve needle. Each spray gun cartridge further includes a manifold body having a central bore into which the spray gun cartridge is removably mounted and liquid and air inlet and outlet passages which communicate with the liquid and air spray gun cartridge passages. The spray gun cartridge is removable from the manifold body without disconnection of fluid supply lines to the manifold body and without removal of the manifold body from a ganged mounted array of such spray modules.

    Abstract: A high-pressure liquid spray nozzle having an elongate nozzle body having a longitudinally extending liquid flow passage, which in the illustrated embodiment, is defined in part by a plastic liquid throttling and stabilizing insert. The insert has a liquid flow passage which includes an upstream entry section, a smaller diameter downstream approach section, and an inwardly converging throat section between the upstream and downstream sections. The upstream passageway section has a scalloped cross-sectional configuration which define a plurality of longitudinally extending flutes effective for stabilizing and minimizing turbulence in the high pressure liquid flow stream directed through the nozzle such that a more concentrated, solid liquid flow stream is discharged from the nozzle with increased velocity and surface impact force for enhanced cleaning.
