Abstract
1317659 Pressure indicator KURODA SEIKO CO Ltd 1 July 1970 [2 July 1969] 31860/70 Heading G1L A device indicating the presence or absence of fluid e.g. air, under pressure comprises a body member 10 having its front end closed by a transparent cap 5, a piston 4 slidably movable against a spring 20 within the body member 10 under the action of fluid-pressure, and a slitted membrane 3 of plastics or thin metal positioned beneath or behind the cap. In the absence of fluid-pressure the spring 20 urges the piston 4 towards the closure 16, whereas when fluidpressure is applied through a bore 18 the piston is forced against the action of the spring through the slitted membrane 3 so that it is visible in the transparent cap region. The membrane may be circular or rectangular and may be slit and provided with holes or slots in various ways, Fig.2 (I-VI) (not shown).
