Abstract

Quick acting blast aerators having rigid accumulation tanks with internal valve assemblies comprising a tubular body, an end cap teat receives air through an inlet controlled by solenoids, and an internal piston that contacts a valve seat during filling, and retracts to expose exhaust vents upon firing. The valve calp comprises a ring groove and an O-ring check valve. An internal dampening passageway vertically extends through the cap. Internal air passageways extend form the passageway to the air-control groove, admitting air into the tank by dislodging the O-ring. The high temperature piston slides between a tank-fill position bearing against the valve seat and a retracted position exposing the exhaust vents. An internal return spring extends between a deep, annular recess in the piston, and a groove formed in the bottom of the end cap. A dampener projecting from the piston is received within the passageway traversing the end cap.
