Abstract

A modular multiple-fluid component selection and delivery system comprised of a main block having a centrally located main passageway intersected by a plurality of secondary passageways. Plug valves are inserted in bores in the block which intersect each respective main and secondary passageway. A valve at the entrance to the main passageway permits flushing the system with a solvent for cleaning the main passageway and spray gun. A check valve at the entrance to the main passageway prevents a backup of fluid components into the solvent supply system. The secondary passageway exits at the sides of the block to which are attached hose connecting fittings. The main passageway terminates in the opposite end of the block in threads for attachment to a main hose to a spray gun for spraying a fluid component such as paint. The exit end of the main passageway also provides a shoulder for an aligning sleeve for attachment of successive blocks in modular form to add additional valve connections for controlling the flow of additional fluid components. Each additional auxiliary block stacks end to end with the previous block with main passageways in each block being aligned by aligning sleeves. Studs of appropriate length are provided according to the number of auxiliary blocks stacked end to end to secure and clamp the blocks to the main manifold or block. Each successive auxiliary block provides control and delivery of two additional fluid components.
