Vorrichtung zur Flüssigkeitsmischung und bedarfsgesteuertes Ventil dafür

摘要

The fluid mixing device includes a housing (2) having two inlets (21, 22) for two fluids to be mixed, a common outlet (23), and a cylindrical chamber (24) connecting the inlets (21, 22) to the outlet (23). A valve member (3) within the cylindrical chamber (24) includes a cylindrical wall (32) formed with a slot (32a) extending for a part of the wall circumference and is displaceable axially for moving its slot (32a) into or out of alignment with inlet slots (25a, 26a) communicating with the chamber (24). The valve member (3) is also presettable angularly to permit presetting the proportion the valve member slot (32a) is coextensive with the inlet slots (25a, 26a), and thereby the proportions of the inletted fluids to be included in the outlet mixture. Also described is a demand valve optionally usable with the fluid mixing device.
