ABSTRACT:
A mixing and extruding nozzle for two reactant components has a housing formed with a mixing chamber, a pair of parallel and oppositely directed faces flanking and turned away from the chamber, respective injection passages having inner ends opening into the chamber and outer ends opening at the respective faces, and respective outwardly open grooves in the faces offset from the passages. A valve-type rocker pivotal relative to the housing about an axis perpendicular to and traversing the two faces and offset from the passages and grooves has two like halves each formed with a face confronting the respective housing face and a feed passage opening at the respective rocker face offset from the axis. This rocker is pivotal about the axis relative to the housing between a feed position with the feed passages aligned with the respective injection passages and opening therethrough into the chamber and a return position with the feed passages out of alignment with the respective injection passages and communicating through the respective grooves with the respective return passages. Respective supplies feed the respective components separately under pressure to the respective feed passages and withdraw the respective components from the respective return passages. Respective seal rings are engaged between the rocker halves and the housing.
