| DIAGRAMMATIC SKETCH OF THE R.R. BOOST REGULATOR. SHEWING SECTION & PRESSURE PASSAGES FROM SUPERCHARGER. TO RELAY PISTON, VIA ANEROID PISTON VALVE. THE POSITION OF THE VARIOUS PARTS ARE SHOWN WHEN AT SLOW RUNNING. WHEN THE CHANGEOVER COCK OPENS THE PISTON SIDE OF THE ANEROID PISTON VALVE TO ATMOSPHERIC PRESSURE TO COMPENSATE FOR THE PRESSURE DIFFERENCE ACROSS THE S/C WHICH AT SLOW RUNNING IS PRACTICALLY NIL.
