Rotary screw compressor — A rotary screw compressor is a type of gas compressor which uses a rotary type positive displacement mechanism. The mechanism for gas compression utilises either a single screw element or two counter rotating intermeshed helical screw elements… … Wikipedia
Compression ratio — For compression ratio in data compression, see data compression ratio. The compression ratio of an internal combustion engine or external combustion engine is a value that represents the ratio of the volume of its combustion chamber from its… … Wikipedia
Rotary valve — A rotary valve is a type of valve in which the rotation of a passage or passages in a transverse plug regulates the flow of liquid or gas through the attached pipes. The common stopcock is the simplest form of rotary valve. Rotary valves have… … Wikipedia
rotary engine — An internal combustion engine which is not of a reciprocating (piston) engine design. There is no true crankshaft, although the power take off shaft is sometimes called the crankshaft. It is stationary or fixed in that it simply spins in place.… … Dictionary of automotive terms

Container compression test — The container compression test measures the compressive strength of packages such as boxes, drums, and cans. It usually provides a plot of deformation vs compressive force. It is commonly used to evaluate shipping containers made of corrugated… … Wikipedia
Pistonless rotary engine — This article is about internal combustion engines that do not use conventional pistons. See also rotary engine (disambiguation) for other uses of this term, and rotary engine for the World War I aircraft engines by that name. A pistonless rotary… … Wikipedia
Britalus Rotary Engine — The Britalus rotary engine was invented in 1982 by Kenneth W. Porter, P.E., M.S.A.E, of King County, Washington. It operates on a modified Brayton cycle, but with continuous pulsed combustion, similar to that of a gas turbine. It can burn most… … Wikipedia
Roots type supercharger — The Roots type supercharger or Roots blower is a positive displacement pump which operates by pulling air through a pair of meshing lobes not unlike a set of stretched gears. Air is trapped in pockets surrounding the lobes and carried from the… … Wikipedia
Gas compressor — A gas compressor is a mechanical device that increases the pressure of a gas by reducing its volume. Compressors are similar to pumps: both increase the pressure on a fluid and both can transport the fluid through a pipe. As gases are… … Wikipedia
