2. Uniflow steam engine - Wikipedia

   en.wikipedia.org/wiki/Uniflow_steam_engine

   The Casablanca-class escort carrier, the most prolific aircraft carrier design in history, used two 5-cylinder Skinner Unaflow engines, but these were not steeple compounds. A non-compound Skinner Uniflow remained in service until 2013 in the Great Lakes cement carrier SS St. Marys Challenger, installed when the vessel was re-powered in 1950 ...

3. Leak-down tester - Wikipedia

   en.wikipedia.org/wiki/Leak-down_tester

   This schematic shows the component parts of a typical leak-down tester. The gauge on the right is held at a standard pressure by adjusting the pressure regulator while the gauge on the left shows an example reading of 85, or 15% leakage. A leak-down tester [2] is essentially a miniature flow meter similar in concept to an air flow bench. The ...

4. Uniflow engine - Wikipedia

   en.wikipedia.org/wiki/Uniflow_engine

   Uniflow steam engine, a steam engine with a long uniflow cylinder that receives inlet steam at each end (for a double-acting engine) and exhausts through ports at the centre. Uniflow diesel engine, a two-stroke diesel engine with inlet through piston-ported fixed ports in the lower part of the cylinder, and exhaust through valves in the ...

5. Engine configuration - Wikipedia

   Similar to U engines, H engines consist of two separate flat engines joined by gears or chains. H engines have been produced with between 4 and 24 cylinders. An opposed-piston engine is similar to a flat engine in that pairs of pistons are co-axial but rather than sharing a crankshaft, instead share a single combustion chamber per pair of ...

6. Poppet valve - Wikipedia

   en.wikipedia.org/wiki/Poppet_valve

   A sectional illustration of Watt's beam engine of 1774 using the device is found in Thurston 1878:98, [13] and Lardner (1840) provides an illustrated description of Watt's use of the poppet valve. [14] When used in high-pressure applications, for example, as admission valves on steam engines, the same pressure that helps seal poppet valves also ...

8. Piston valve (steam engine) - Wikipedia

   en.wikipedia.org/wiki/Piston_valve_(steam_engine)

   The usual locomotive valve gears such as Stephenson, Walschaerts, and Baker valve gear, can be used with either slide valves or piston valves. Where poppet valves are used, a different gear, such as Caprotti valve gear may be used, though standard gears as mentioned above were used as well, by Chapelon and others.
