<p>The most strained component of a cartridge is the bush, in which the control lever is mounted, using which the control can is moved. Upon actuation of the control lever to open and close the intakes and drains, the bush and thus also the extension of the housing and the front wall thereof are strained by bending. Upon mixing of the cold and hot water streams, friction forces arise in directions, which are perpendicular to one another, between the bush and the front wall of the housing and in the extension of the housing by rotation of the bush. All of these strains can result in hysteresis in the mixing position and in the position of the control cam during the opening and closing movements because of tolerances and play the opening and closing movements because of tolerances and play between the individual components. To overcome the strain issues, the bush bus has the control lever mounted therein is mounted using a conical face and also conical part of the front wall of the cylindrical housing.</p> |
