While Fig. 229 shows full releaseposition, still ports s and g are fully shown, and if thehandle is moved to running position the port throughthe rotary that registers with port e in Sec. 3, would bein register with port/; port g is indicated by dotted lines. In running position, when the trainpipe and littledrum are charged up to seventy pounds there is alsoseventy pounds on top of the diaphragm piston, andas the regulating spring is set at a fraction less thanseventy, the air pressure forces it down and allows thesupply valve to seat and shut off the main reservoirfrom the trainpipe. But as soon as the pressure in thetrainpipe falls below seventy, the piston is again forcedup by the re
