Coaxial paint hose and supply system

摘要

A flexible coaxial conduit in a recirculating paint supply system disposed between a flow control restrictor connected to a paint spray nozzle and a pressurized paint supply line and return line for supplying paint to the nozzle in a quantity in excess of that required to provide continued recirculation and uniformity in the composition and quality of the liquid coating composition. The coaxial conduit is substantially transparent and in a preferred embodiment, the outer tube is of a composite construction to provide optimum flexibility while retaining resistivity to the attack from the liquid paint composition.
