DETAILS OF OPERATION. The Vapor Regulator is divided by partitions intothree parts (see Figure 39), a high pressure chamber di-rectly under the automatic valve A, a low pressureor supply chamber directly above the automatic valve,and an outlet chamber where the return or drain pipefrom the heating pipes inside of the car is connectedto the regulator. 110 RULES FOR MOVEMENT OF TRAINS.
