Abstract

1,057,815. Fluid actuation of switches. BAILEY & MACKEY Ltd. Aug. 31, 1964 [Oct. 4, 1963], No. 39093/63. -Heading H2B. [Also in Division G1] In a differential pressure gauge or switch a pair of chambers 10, 12 are separated by a flexible diaphragm 18 and a piston 20, secured to the diaphragm 18, has arms which extend into and through each chamber 10, 12 and are fluid-tight sealed to the walls of each chamber 10, 12 either by a roll-up seal 26 or 0-ring between the piston arms and the walls of each chamber 10, 12.
