Abstract

1,079,839. Pressure gauge. DONALDSON CO. Inc. July 4, 1966 [April 25, 1966J, No. 29957/66. Heading G1L. A gauge for indicating the alteration in suction pressure in an air intake 18 of an I.C. engine and connected to the air intake 18 between a filter 15 and the engine has a bellows 31 exposed on one side, through an apertured cap 24, to atmosphere and on the other to the engine intake and the arrangement is such that should the filter 15 become contaminated the pressure difference across the bellows 31 will increase and thus expand the bellows 31 to expose an element 34 which may be coloured, through a transparent lower portion 29 of a housing 22. The bellows 31 is held in the expanded position, if the engine is stopped, by a member 47 which is released by depressing a button 55.
