Tlic ralro is known as a " balanced valve," 80 nnanged as to open and close by a single movemcnt of the operator. The time of opening and closing caii be varied by an adjusting dcvicc so that any desired loss of prcjsnro will ensue. In this way the rimge can bc cliangcd witliout change either of clcvation or prcssurc. Tlio -ialvo scttiug can be constantly changed to conform to the variations of rango rnucli more quickly and accurately tlian can bc ncconiplislicd by correspond: ing change of elcvntion of n gun. The prcssnro in.tIic rcscrvoir is reduced a t each fire by any predetermined amount, thc valve being ndjustnble to nccornplisli this nutomatically. Tlie most ccoiiomical results are obtained with tho air acting exp:insivcly. A loss of 12 to 15 per cent. with (L reservoir of five capacities of thc gun-bore is ordiuarily the mnsiiiiuln which cau bc uscd with advantage.
