LNER Class V2 4771 Green Arrow.Note Gresley conjugated valve gear located ahead of the piston valves, driven from the valve spindles. The Gresley conjugated valve gear is a valve gear for steam locomotives designed by Sir Nigel Gresley, chief mechanical engineer of the LNER, assisted by Harold Holcroft.
Cut-away drawing of steam engine speed governor. The valve starts fully open at zero speed, but as the balls rotate and rise, the central valve stem is forced downward and closes the valve. The drive shaft whose speed is being sensed is top right Porter governor on a Corliss steam engine. The devices shown are on steam engines.
The Walschaerts valve gear is a type of valve gear used to regulate the flow of steam to the pistons in steam locomotives, invented by Belgian railway engineer Egide Walschaerts in 1844. [ 1 ] [ 2 ] The gear is sometimes named without the final "s", [ a ] since it was incorrectly patented under that name.
The Walschaerts valve gear on a steam locomotive (a PRR E6s).. The valve gear of a steam engine is the mechanism that operates the inlet and exhaust valves to admit steam into the cylinder and allow exhaust steam to escape, respectively, at the correct points in the cycle.
The gear was first tested on Mikado 586 in February, 1913 at Southern Knoxville Shops. It was specified for some USRA standard locomotive designs, though many locomotives constructed to these patterns used Walschaerts or Baker valve gear instead. The Southern valve gear was used on many Southern Railway locomotives, including survivors 630 and 722.
[5] [7]: 18 Early American locomotives had bar frames, made from steel bar; in the 20th century they usually had cast steel frames or, in the final decades of steam locomotive design, a cast steel locomotive bed – a one-piece steel casting for the entire locomotive frame, cylinders, valve chests, steam pipes, and smokebox saddle, all as a ...
