Cyclopedia of locomotive engineering, with examination questions and answers; a practical manual on the construction care and management of modern locomotives . the Distributing Valve to theAutomatic Brake Valve through the Double Cut-OutCock. ARRANGEMENT OF APPARATUS. A piping diagram of the ET equipment is shown inFig. 295. Air compressed by the pump passes as usual to themain reservoirs and the reservoir pipe. The main-reser-voir cut-out cock is to cut off the supply of air whenremoving any of the apparatus except the governor. Theend toward the main reservoir is tapped for a connectionto the maximum pressure head of the Pump closed it discharges the air from the pipe betweenit and the automatic brake valve. Beyond the main-reservoir cut-out cock3 the reser-voir pipe has four branches, one of which runs to theautomatic brake valve, one to the feed valve, one to thereducing valve, and one to the distributing valve. As aresult, the automatic brake valve receives air from themain reservoir in two ways, one direct and the otherthrough the Feed Valve. The Feed-Valve Pipe feed valve to the auto- 6y2 LOCOMOTIVE ENGINEERING. a HH HO i—ii—i a* OS d ET BRAKE EQUIPMENT 673 matic brake valve has a branch to the top of the excess-pressure head of the duplex pump governor. The third branch of the reservoir pipe connects withthe reducing valve. Air at the pressure for which thisvalve is set (45 pounds) is thus supplied to the indepen-dent brake valve through the reducing-valve pipe. Whenthe signal system is installed, it is connected to the re-ducing valve pipe, in which case the reducing valve takesthe place of the signal reducing valve usually employedto suprjry-the train air-signal system. In the branch pipesupplying the signal are placed a combined strainer andcheck-valve, and a special choke fitting. The former pre-vents any dirt from reaching the check valve and chokeplug. The check valve prevents air from flowing backfrom the signal pipe when t
