Abstract

An impingement mixing device is provided comprising a mixing chamber housing, a control piston axially displaceable with said mixing chamber housing between an extended position and a retracted position, a mixing chamber within the housing defined by an end face of the control piston when in the retracted position and a mixing chamber discharge outlet coextensive with an end face of said control piston when in the extended position, means to feed first and second components to the mixing chamber in opposing relationship, a discharge tube housing defining a quieting chamber having an opening at a discharge end and in fluid communication with the mixing chamber, with said discharge tube housing including a sealing means adapted to at least partially close the opening of the quieting chamber at the discharge end.
