Abstract

419,920. Pressure-regulating valves. DEGEA AKT.-GES. (AUERGES.), 16, Rotherstrasse, Berlin.-(Assignees of Deutsche Gasgl³hlicht - Auer - Ges. ; 16, Rotherstrasse, Berlin.) March 17, 1934, No. 8485. Convention date, March 18, 1933. Addition to 405,870. [Class 135.] A pressure-reducing valve for use with breathing apparatus for high altitudes of the kind claimed in the parent Specification has the gas filled container for varying the adjustment of the loading spring in the form of a metal accordion bellows f with rigid end surfaces. The actuating diaphragm c preferably acts on the valve member b through a lever arrangement as described in Specification 393,877.
