500,976. Valves. BRONZAVIA SOC. ANON. Aug. 19, 1937, No. 22810. Convention date, Nov. 28, 1936. [Class 135] A pressure-regulating valve and a manometer are arranged in a single casing as a unit which is especially suitable for supplying oxygen in aircraft at high altitudes. The casing 5 has an extension 21 for attachment to the union 22 of an oxygen container 6 and contains a valve 2 actuated by a diaphragm 1 subjected to the delivery pressure and a Bourdon tube 7 which is in communication with the pressure in the container through passages 16, 19 and operates a pointer 9 which is visible through a window 20 of the casing and moves along a scale 18 to give an indication of the state of the supply of oxygen in the container 6.
