Abstract

1402435 Fluid-pressure servomotor systems AIRFINA ETABS 28 Nov 1972 [1 Dec 1971 7 July 1972] 54847/72 Heading G3P [Also in Divisions F1 and F2] When the pressure in an outlet 26 of a rotary air-compressor driven by an electric motor M reaches an upper limit a pressure switch 89 opens and causes a solenoid valve 91 to shift to a position L and consequently a pressure valve 92 to assume a corresponding position L in which it vents a space between filters 20, 21 to the atmosphere. The pressure loss in said space closes a non-return valve 25 and this in turn moves a ball-valve 93 so as to transmit the pressure in the outlet 26 by way of the valve 91 to the valve 92 and hold the latter in its position L.
