The port openings in the lower caseand the base of the rotary valve seatmust, of course, register with the open-ings through the gaskets and on a No. 6equipment, port shown as No. 1 leads tothe release pipe and exhaust port of theequalizing slide valve and port No. 2leads to a branch pipe to the applicationcylinder pipe. On the No. 5 equipment port No. 1leads to the application chamber pipe andport No. 2 to the branch of the double PORT-2 PORT-1.

As the admission of main reservoirpressure, the equalizing discharge featureand the exhaust of brake pipe pressure isidentical in both brake valves, the sameports through the lower case conduct thepressure to and from the brake systemregardless as to whether the upper por-tion is of the H 5 or H 6 brake valve,but the two numbered ports are used fordifferent purposes by the two valves. Knowing where these ports lead to wewill assume that the No. 6 equipment hasin some way had an H 5 brake valveapplied to it and we wish to know itseffect. It is manifest that the brakes will applyand release in the same way that the H 6brake valve would apply or release them,but when the valve handle of the H Sbrake valve was returned to lap positionthe app
