Abstract
An upper valve component for a sanitary fixture including a sleeve type head fastenable in a valve housing and a spindle which extends through the center of the sleeve head and is equipped with a socket head, the spindle having exterior annular faces which radially position it within the sleeve head. The exterior annular face of the spindle includes a number of annular grooves therearound, some of which are provided with sealing rings to seal the spindle within the sleeve head. At the end of the sleeve head which is proximate the socket head of the spindle, there is an internal annular recess. The valve component includes a pretensioned elastic bearing which is insertable into the annular recess between the spindle and the sleeve head can be removed or inserted without disassembly of the valve. The bearing has an external surface which presses against the internal surface of the recess and has an internal surface which bears against the spindle. The bearing also includes a flange extending inwardly for locking engagement with one of the annular grooves in the spindle to inhibit rotation of the spindle.
