The Backus vertical engine
The Backus vertical engine is illustrated in Fig, 124, and a section in Fig. 125. The valves are of the poppet type. The exhaust valve has its motion controlled by a cam on the reducing-gear, while the gas valve is governed by a centrifugal governor in the pulley. The governing is by limiting or shutting off the gas, but the general regulation is made by an index valve. The gas inlet is through the air-inlet valve seat, so that when the engine stops the air valve closes the gas inlet by the action of its spiral spring, which is not shown. This is independent and automatic, and prevents the escape of gas by leaving the gas valve open.
The concave piston and cylinder head are shown in the cut; the gas inlet at a, combined gas-and-air valve at b, and the exhaust valve at d. |
