Patent GB-2054207-A (GB)
Title: Valves and breathing apparatus incorporating such valves
IPC: G05D16/06
Filed: 1980-06-20
Abstract: A valve, notably for use as a demand valve in breathing apparatus, has a pressure-responsive diaphragm (25) coupled to a separate control member (18) which lies in the path of a jet of gas which vents from a control chamber (14) through an orifice (17), gas being continuously supplied to the control chamber via another orifice (16). Deflection of the diaphragm in response to pressure changes in a chamber (42) caused by inhalation and exhalation pivots the control member towards or away from the orifice (17) to control the rate of venting from the control chamber and thereby vary the pressure within the control chamber. Flow of gas through the valve to the user of the apparatus is controlled by a flexible disc (10) which in turn responds to the pressure in the control chamber. By employing a separate diaphragm (25) and control member (18) the former can be optimised for pressure-response while the latter can be optimised for valve-regulation by interaction with the gas jet from the control chamber. <IMAGE>
