ABSTRACT:
An inverted, manually operable, cylindrical, inverted-cup-shaped valve element is turnable axially back and forth between an open position in which an aperture in said element's side wall registers with a fluid passage of a fixed central core of the valve and an opening in the housing of the valve to permit fluid to flow therethrough and a closed position in which a non-apertured portion of said element's side wall registers with the valve's said fluid passage and said opening to close said passage against flow of fluid therethrough. An operating knob is provided for manually turning said valve element, and means are provided for limiting the turning of said valve element to considerably less than a full turn.
