Abstract
A disc-like valve element in a control valve includes an outer peripheral ring to which leaf elements are integrally connected having a thickness which increases uniformly from the entire outer peripheral ring to the axial center forming a conical shaped valve element when in a closed condition. The side of the valve element facing the inlet end of the chamber is preferably flat functioning as a funnel to discharge urine when the valve element is moved to an open condition. The increased thickness at the axial center of the valve element is preferably the result of the side of the valve element facing the outlet end of the valve chamber increasing in thickness from the ring laterally inwardly and longitudinally outwardly to maximize flexibility of the leaf elements adjacent the ring and sealing at the axial center.
