Patent ID: 6874702

Claim:
A modular spray apparatus, comprising: a handle module including a first housing having an inlet adapted to be coupled to a source of pressurized gas, a flow passage extending between the inlet and an outlet, and a first coupling member proximate the outlet; and a head module including a second housing having a second coupling member removeably coupled to the first coupling member of the first housing, the second housing including a first intake port fluidly communicating with the outlet of the handle module, a second intake port adapted to be coupled to a source of liquid material, a mixing passage fluidly communicating with the first and second intake ports and with a spray outlet, the head module further including a nozzle fluidly communicating with the spray outlet, and a needle assembly operatively coupled to the second housing and operatively associated with the nozzle to control a flow of liquid material and pressurized gas emanating from the mixing passage through the nozzle, whereby the second coupling member of the head module may be de-coupled from the first coupling member of the handle module without disassembly of the head module.
