Collects steam at the top of the boiler (well above the water level) so that it can be fed to the engine via the main steam pipe, or dry pipe, and the regulator/throttle valve. [2] [5] [6]: 211–212 [3]: 26 Air pump / Air compressor Westinghouse pump (US+) Powered by steam, it compresses air for operating the train air brake system.
Diagram of cylinder and piston valve. The valve is next opened by moving it to the right, allowing the clear space in the middle of the valve to align with the channel in the cylinder above it. Piston valves are one form of valve used to control the flow of steam within a steam engine or locomotive.
Many steam locomotive toys have been made, and railway modelling is a popular hobby. Steam locomotives are often portrayed in fictional works, notably The Railway Series by the Rev W. V. Awdry, The Little Engine That Could by Watty Piper, The Polar Express by Chris Van Allsburg, and the Hogwarts Express from J.K. Rowling's Harry
The way the valve controlled the steam entering and leaving the cylinder was known as steam distribution and shown by the shape of the indicator diagram. What happened to the steam inside the cylinder was assessed separately from what happened in the boiler and how much friction the moving machinery had to cope with.
Firebox of a GWR 6959 Class steam locomotive, showing the underside of the brick arch, constructed from specially-shaped firebricks. Empty firebox of a Baureihe 52, showing the brick arch There is a large brick arch (made from fire brick ) attached to the front wall (boiler throat plate) of the firebox immediately beneath the firetubes.
The main moving parts of a steam locomotive with Walschaerts valve gear: 1 - Link, 2 - Eccentric crank, 3 - Radius rod, 4 - Lap/lead lever, 5 - Crosshead, 6 - Valve, 7 - Cylinder, 8 - Reach rod. A detailed animation of the exterior working parts of a steam locomotive. This animation is from the commons, and is already a featured picture there..
A steam engine is a heat engine that performs mechanical work using steam as its working fluid. The steam engine uses the force produced by steam pressure to push a piston back and forth inside a cylinder. This pushing force can be transformed by a connecting rod and crank into rotational force for work.
A Climax locomotive is a type of geared steam locomotive built by the Climax Manufacturing Company (later renamed to the Climax Locomotive Works), of Corry, Pennsylvania. These had two steam cylinders attached to a transmission located under the center of the boiler, which sent power to driveshafts running to the front and rear trucks. Some ...
