Abstract
A cartridge for use in a spray system, and for releasable connection to a quick-release coupling to form a nozzle assembly. The cartridge includes a generally elongated and hollow body member having a proximal end and a distal end. A nozzle tip is retained at the distal end of the cartridge, and the proximal end is adapted to fit, at least in part, within the quick-release coupling. The body member includes a shoulder for retaining the nozzle tip. In a basic embodiment, the cartridge includes a generally hollow tubular spacer which fits, at least partially, inside the body member, for pressing the nozzle tip against a shoulder formed by the body member at the distal end. An O-ring is disposed between the shoulder and the spacer, in order to seal the cartridge and to prevent leakage. A screw fits within the proximal end of the body member for retaining the spacer in tight engagement with the nozzle tip. In other embodiments, the cartridge includes a plurality of components, such as a sequence of filters and a check valve. The basic embodiment of the cartridge is assembled by fitting the O-ring on the nozzle tip; by inserting the nozzle tip inside the body member; by introducing a sp…
