Theresulting increase of pressure in the brake pipe and in chamber G FEED VALVES. 6i above diaphragm 57 continues until it becomes sufficient to over-come the tension of regulating spring 67, adjusted at seventypounds. Diaphragm 57 then allows regulating valve 59 to beseated by spring 60, thus closing port a, and cutting off all com-munication between chamber E and the brake pipe. The pressuresin chambers F and E then become equalized, through leakage pastsupply valve piston 54, and supply valve piston spring 58, whichis compressed by the relatively high pressure in chamber F, nowreacts and forces supply valve 55 to its normal position, closingport b and cutting off communication between the main reservoirand the brake pipe.
