Abstract
A self closing safety gate valve controls the flow of heavy, viscous fluids such as machine oil, rubber cement, lacquer, or the like. The valve housing contains a rotor with a spring biased thrust exerted laterally against the rotor, to hold it--in normal position--against the housing wall with a metal-to-metal seal at the output orifice. When the rotor turns, a pair of large output orifice openings, in the housing and rotor, are aligned--in off-normal position--in order to enable the out flow of fluid. A spring biased handle automatically returns the rotor from the off-normal to the normal position, where the thrust again presses the rotor body against the large output orifice opening in the housing.
