Abstract
1324669 Respiratory appliances DRAGERWERK AG 15 June 1972 [15 June 1971] 28176/72 Addition to 1264085 Heading AST [Also in Divisions Gl and G3] A duct 20 supplying oxygen to a respiratory apparatus is connected to a valve 4 which opens if the pressure falls below a predetermined value to allow oxygen from a duct 21 to flow to a whistle 15 and to a chamber 16 through a restrictor 14 in a valve 12 to close the latter by acting on a control means 22, 23 when the chamber pressure has risen sufficiently. Further escape of oxygen is thus prevented. The duct 21 is supplied through a pressure reducer from the duct 20. On putting the apparatus into operation, a small quantity of oxygen, escapes through the whistle before the valve 12 closes. Diaphragms or a stepped plunger may be used as the control means 22, 23.
