EFFECT OF PRESSURE OR SUCTION IN COMBUSTION CHAMBER ON CONTROL WITH A CROSS-CONNECTED SYSTEMWITH BLEEDER
A 2 osi combustion chamber pressure or suction is imposed on top of the diaphragm, but, without line (M), the bleeder reduces it to 50% or 1 osi on the bottom of the diaphragm. To correct this condition the bleed opening should be connected to the burner mounting by line (M).
