Sinopsis
This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1913 edition. Excerpt: ...air. This is done by closing cut-out cock ISTo. 3 in the straight air pipe below the engineers' brake valve. See Fig. 5. Pump Governor and Pressure Controller. The pump governor and the pressure controller are one and the same mechanism, though applied to separate uses and differently adjusted, and the description of one covers both. The straight air controller is a similar, though in part smaller, piece of mechanism, and is adjusted for its own particular service of restricting the straight air brake cylinder pressure to 40 pounds to the square inch. The pump governor or pressure controller consists of two parts, the regulating heads and the supply bases. The heads of the pump governor, the pressure controller and the straight air controller of this equipment are all alike in make and size. The supply portions of the pump governor and pressure controller are also alike in make and size, but the straight air controller is made for a f-inch pipe, while the others are used on 1-inch pipes. The controller is made with heads in two styles, single or duplex, to meet the requirements of the different schedules. The single head controllers go with the schedules previously described, but on the B-3--HP schedule, which we are now considering, the duplex heads are used on the pump governor and the pressure controller. Fig. 59 is a sectional view of the duplex pressure controller or of the pump governor head. Fig. 60 is a sectional view of the base, and Fig. 01 is a section of the single head. Referring to the piping diagram, Fig. 58, of the high pressure control, Schedule B-3--IIP, it will be seen that the duplex head of the pump governor is connected to the pipe leading to the duplex air gauge, and main reservoir pressure reaches the heads. On the...
