Abstract
241,089. Wellesley, G., and Coxeter & Son, Ltd. March 7, 1925. Pressure-regulating valves.-The pressure in a gas bag 1, more particularly for supplying anaesthetics, is automatically regulated by means of an elastic band 2 disposed round the bag and connected with a pair of arms 3, one integral with a carrier 4 and the other pivoted on the carrier to compress the inlet tube 5. A spring arm 9 with a regulating screw 10 limits the movement of the pivoted arm and so regulates the pressure to be maintained. Fig. 3 shows a modification in which a foot-controlled rod 14 operates rods 11 which bear at their other ends 8<a> on the inlet tubes of two bags which may contain different gases. The arms 3 may be on the same side of the bag the band 2 being crossed and may be connected by springs or the like. The arms 3 are fitted with rounded ends or rollers 7, 8.
