An illustration of Hero's aeolipile. An aeolipile, aeolipyle, or eolipile, from the Greek "Αἰόλου πύλη," lit. ' Aeolus gate ', also known as a Hero's (or Heron's) engine, is a simple, bladeless radial steam turbine which spins when the central water container is heated.
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.

1790 (): Nathan Read invented the tubular boiler and improved cylinder, devising the high-pressure steam engine. 1791 (): Edward Bull makes a seemingly obvious design change by inverting the steam engine directly above the mine pumps, eliminating the large beam used since Newcomen's designs. About 10 of his engines are built in Cornwall.
The company introduced high-pressure steam engines to the riverboat trade in the Mississippi watershed. The first high-pressure steam engine was invented in 1800 by Richard Trevithick. [44] The importance of raising steam under pressure (from a thermodynamic standpoint) is that it attains a higher temperature. Thus, any engine using high ...
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. Corliss assumed the original invention from Frederick Ellsworth Sickels (1819- 1895), who held the patent (1829) in ...
Jan Ridders (Roosendaal, 1941) is a Dutch machinist, engineer and machine designer. [1]Ridders' designs, freely distributed, [2] along with assistance to engineers building these motors, has brought him world reputation. [3]
Waverley is powered by a three-crank diagonal triple-expansion marine steam engine built by Rankin & Blackmore, Engineers, Eagle Foundry, Greenock, Scotland. [19] It is rated at 2,100 IHP and achieved a trial speed of 18.37 knots (34.02 km/h; 21.14 mph) at 57.8 rpm. Passengers can watch this engine from passageways on either side of the engine ...
