<p>There is disclosed a float valve assembly of the type especially well suited to control the flow of inlet water to a toilet tank having a lavatory defined by its cover. The invention relates in particular to a means of making the fitting suitable for use in toilets having different optimal fill levels, and in particular to a means of adjusting the fill level which involves rotation of the rod attached to the float ball on its longitudinal axis. A lead screw-type mechanism causes a connecting linkage to move along the rod into response to such rotation.</p> |
