The choke fitting prevents the reducing valvefrom raising the signal pipe pressure so quickly as to preventthe operation of the signal system. Distributing Valve Connections. The distributing valve hasfive pipe connections made through the end of the double cham-ber reservoir, three to the left and two to the right. Of the threeon the left, the upper is the supply pipe, leading from the mainreservoir; the intermediate is the application cylinder pipe, lead-ing to the independent and automatic brake valves, and the loweris the distributing valve release pipe, leading through the inde-pendent brake valve to the automatic brake valve, when the han-dle of the independent brake valve is in running position.
