Abstract

1,143,153. Pressure switch. DRESSER INDUSTRIES Inc. 19 April, 1967 [12 May, 1966], No. 18095/67. Heading H1N. The pressure range of a pressure responsive control device is altered by replacing a unit which comprises a piston 22 movably mounted in and radially spaced from its stepped cylinder 24 by a spring spider 26. The piston 22 is acted on by a rubber diaphragm 34 which closes a passageway 10 of the housing. The force transmitted to the piston is a function of the area of contact between the piston and diaphragm and thus by providing units having different diameter pistons, different pressure ranges can be provided. The piston acts on a switch by means of a spring biased disc 38 and rod 48. The diaphragm 34 is sealed in position by an 0-ring 36 clamped by bolts 18.
