ABSTRACT A self-closing valve assembly for sanitary installations is disclosed. The valve assembly includes upper and lower valve housings which define a metering chamber that is normally filled with a metering fluid. A metering means, shiftably mounted in the lower valve housing, includes a first one-way valve means which displaces a predetermined volume of the metering fluid when said valve assembly is shifted to its opened position. A closure means, which includes a second one-way valve means, is operably coupled to the metering means to automatically shift said metering means from its opened to its normally closed position, by transferring the displaced volume of said metering fluid in the metering chamber through a second one-way valve means after a predetermined period of time has elapsed, to thereby close said valve assembly.
