Abstract

Flow rate control device comprises a housing, a housing inlet for coupling to a liquid flow supply, a housing outlet, a first housing wall portion defining a throughflow path communicating at the ends thereof respectively with inlet and the outlet, a second housing wall portion defining a chamber communicating with the inlet and being otherwise closed, a flexible wall portion common to the first and second wall portions and serving as a separating partition between the chamber and the flow path. At least the first housing wall portion is formed with at least one tapering protrusion extending into a flow path so as to form a construction therein and is shaped so that upon maximum displacement of the flexible wall portion into the flow path a permanent residual flow path remains open.
