FLOW VOLUME CONTROLLER FOR SANITARY APPLICATIONS AND METHOD FOR CONFIGURING SAID FLOW VOLUME CONTROLLER

摘要

The invention relates to a flow volume controller for sanitary applications having a housing having an annular-gap-like through-passage and furthermore having an elastic throttle body arranged near the annular gap which changes the annular gap or sections thereof due to elastic deformation upon the formation of pressure differences in the flowing medium, wherein the annular gap has a profile and the elastic throttle body is supported having the outflow side surface thereof on a support shoulder which is a component of the housing. According to the invention, either a retaining ring, a retaining bulge or a plurality of retaining tabs is provided on the inlet side for axial attaching of the elastic throttle body, wherein the retaining ring or the retaining tabs substantially cover the projected inflow side surface of the throttle body to a maximum of one half, preferably to a maximum of one third when viewed from the inflow side, such that the flow pressure of the flowing medium sufficiently engages on the throttle body and discontinuity points in the control characteristics are prevented. The invention also relates to a method for configuring symmetrical profiling of an annular gap for flow volume controllers and a production method for said controllers.
