Abstract
1285269 Pressure gauge SOC ANON DES ETABS JOUVENEL & CORDIER 15 Oct 1970 [17 Feb 1970] 49146/70 Heading G1L In a device for indicating the presence or absence of a fluid under pressure within a hydraulic or pneumatic apparatus a resilient diaphragm 14, attached to or integral with a plunger 16, is seated on flanges 17 and 20 and when the diaphragm 14 is subjected to fluid-pressure through a duct 18 the plunger 16 is projected to the indicator position. The diaphragm 14 in the operative position forms a seat with the conical surface 21 on the cap 12.
