Abstract

339,819. Ebert, A. Jan. 2, 1930. Lift valves; actuating-mechanism.-A gas valve f, more particularly for gas mains, is opened and closed by means of inclined surfaces a disposed concentrically on the cover of the valve casing i, the inclined surfaces co-operating with rollers d arranged on one or more crossheads c on the rotary valve spindle b. At their upper ends the inclined surfaces a have rest depressions g, ending in limit stops h, to locate and retain the valve in its closed position.
