steamer, is a type of steam-powered vessel, typically ocean-faring and seaworthy, that is propelled by one or more steam engines that typically move (turn)...

An oscillating cylinder steam engine (also known as a wobbler in the US)[citation needed] is a simple steam-engine design (proposed by William Murdoch...

expansion valve is a device in steam engine valve gear that improves engine efficiency. It operates by closing off the supply of steam early, before the piston...
