Abstract

12,142. Armaturen und Maschinenfabrik " Westfalia " Akt. - Ges. May 22. [Addition to 12,062/12.] Check or non-return valves.-Relates to an air - relief valve of the kind described in the parent Specification for use with diving-apparatus, and in which a lip-valve is used in combination with a lift check valve. According to the present invention, the lip - valve d is so arranged over the air-outlet c that the tension of the spring b on the valve a can be adjusted by the screw e without turning the valve d.
