Patent ID: 6991185

Claim:
A foam dispensing gun for dispensing a stream of foam formed by reacting two streams of foam components together, the gun comprising: a body portion, a handle depending from the body portion, a trigger for actuating said gun, a nozzle for dispensing said formed foam from said gun; said body portion including an integrally molded valve seat extending transversely therethrough, the valve seat including integrally molded seal passages formed therein and oriented transverse thereto, a spool valve capable of rotation disposed in said valve seat, the spool valve having a pair of flow passages extending therethrough; the spool valve operatively engaging said trigger such that movement of said trigger rotates said spool valve within said valve seat; said body portion further including a pair of inlet passages defined therein that extend longitudinally there through generally parallel to a longitudinal axis of said gun, whereby said trigger may be selectively moved to rotate said spool valve and bring said spool valve flow passages into communication with said seal passages to thereby define a path for foam components to flow through said spool valve to said nozzle; said spool valve flow passages and said seal passages having non-circular cross-sections.
