An oscillating cylinder steam engine is a variant of the simple expansion steam engine which does not require valves to direct steam into and out of the cylinder. Instead of valves, the entire cylinder rocks, or oscillates, such that one or more holes in the cylinder line up with holes in a fixed port face or in the pivot mounting ( trunnion ).
Original - A cutaway of a steam locomotive, with a numerical guide to the parts. Full guide at Steam locomotive components. Reason Here be a beautiful illustration of the inner workings of a steam locomotive, albeit with some parts present and missing due to engineering difference between the various types of steam locomotives throughout the years.
The cut-off point determines the moment when the valve blocks a steam port, "cutting off" admission steam and thus determining the proportion of the stroke during which steam is admitted into the cylinder; for example a 50% cut-off admits steam for half the stroke of the piston. The remainder of the stroke is driven by the expansive force of ...

A double acting engine is an engine where steam is applied to both sides of the piston. Earlier steam engines applied steam in only one direction, allowing momentum or gravity to return the piston to its starting place, but a double acting engine uses steam to force the piston in both directions, thus increasing rotational speed and power.

A Corliss steam engine – the valve gear is on the right of the cylinder block, on the left of the picture. A Corliss steam engine (or Corliss engine) is a steam engine, fitted with rotary valves and with variable valve timing patented in 1849, invented by and named after the US engineer George Henry Corliss of Providence, Rhode Island.
