The exhausting of thesteam from the small pipe, by means of the cab valve, is fol-lowed by the closing of the reducing check valve, and by theopening of the reducing equalizer valve by the excess pressureon the under side, thus establishing communication with thereceiver, and allowing the reducing valve to open, admittingthe proper supply of steam from the direct steam passage inthe high pressure cylinder saddle.
