SOLVENT FLUSHING ARRANGEMENT FOR FOAM DISPENSING GUN

摘要

A flushing arrangement for a foam dispensing gun operation to dispense at least one resin component which solidifies on exposure to air and including a gun body with an internal passageway adapted to be closed by a valve to establish a passageway portion located downstream from the valve in the context of resin flow past the valve when opened. The flushing arrangement includes a port extending from the exterior of the gun body to the passageway portion immediately downstream from the closed valve so as to enable the circulation of solvent from a pressurized source, such as a squeeze bottle, throughout all surfaces with which the resin comes in contact in the passageway portion.
