Abstract

758,164. Respiratory apparatus. BRITISH OXYGEN CO., Ltd. Aug. 20, 1954 [Aug. 20, 1953], No. 24300/54. Class 81(2). [Also in Group XXIX] A valve for controlling inhalent gases has a shuttle valve 9, 10 spring- loaded to close an inlet 3 and moved by a positive inlet pressure pulse to close a coaxial exhaust 12, a lateral connection 4 from the valve chamber 2 for inhalation, and a spring-loaded valve 15 in the exhaust. A relief valve 19 controls a coaxial lateral passage 6. With normal suction pressure in chamber 2, valve 9 opens but valve 10 does not close.
