Piston
A piston is a component of reciprocating engines, reciprocating pumps, gas compressors, hydraulic cylinders and pneumatic cylinders, among other similar mechanisms. It is the moving component that is contained by a cylinder (engine), cylinder and is made gas-tight by piston rings. In an engine, its purpose is to transfer force from expanding gas in the cylinder to the crankshaft via a piston rod and/or connecting rod. In a pump, the function is reversed and force is transferred from the crankshaft to the piston for the purpose of compressing or ejecting the fluid in the cylinder. In some engines, the piston also acts as a valve by covering and uncovering Porting (engine)#Two-stroke porting, ports in the cylinder. __TOC__ Piston engines Internal combustion engines An internal combustion piston engine, internal combustion engine is acted upon by the pressure of the expanding combustion gases in the combustion chamber space at the top of the cylinder. This force then acts dow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydraulic Cylinder
A hydraulic cylinder (also called a linear hydraulic motor) is a mechanical actuator that is used to give a unidirectional force through a unidirectional stroke. It has many applications, notably in construction equipment ( engineering vehicles), manufacturing machinery, elevators, and civil engineering. A hydraulic cylinder is a hydraulic actuator that provides linear motion when hydraulic energy is converted into mechanical movement. It can be likened to a muscle in that, when the hydraulic system of a machine is activated, the cylinder is responsible for providing the motion. Operation Hydraulic cylinders get their power from pressurized hydraulic fluid, which is incompressible. Typically oil is used as hydraulic fluid. The hydraulic cylinder consists of a cylinder barrel, in which a piston connected to a piston rod moves back and forth. The barrel is closed on one end by the cylinder bottom (also called the cap) and the other end by the cylinder head (also called th ...

Fire Piston
A fire piston, sometimes called a fire syringe or a slam rod fire starter, is a device of ancient Southeast Asian origin which is used to kindle fire. In Malay it is called "gobek api." It uses the principle of the heating of a gas (in this case air) by rapid and Adiabatic process, adiabatic compression to ignite a piece of tinder, which is then used to set light to kindling. Description and use A fire piston consists of a hollow Pneumatic cylinder, cylinder sealed at one end and open at the other. Sizes range in length from 3 to 6 inches (7.5 to 15 cm) with a bore about 0.25 inch (6–7 mm) in diameter, to 10 to 14 inches (25 to 35 cm) with a bore about 0.5 inch (14 mm) in diameter. A piston with an airtight circular Seal (mechanical), seal is fitted into the cylinder. A string packing lubricated with water or rubber gasket lubricated with grease is used to create an air-tight but slippery seal. At the end of the piston a small cavity is made, where tinde ...

Piston (optics)
In optics, piston is the mean value of a wavefront or phase profile across the pupil of an optical system. The piston coefficient is typically expressed in wavelengths of light at a particular wavelength. Its main use is in curve-fitting wavefronts with Cartesian polynomials or Zernike polynomials. However, similar to a real engine piston moving up and down in its cylinder, optical piston values can be changed to bias the wavefront phase mean value as desired. As phase values can only vary from zero to 2π, then repeat in either direction (termed phase wrapping), changing the piston coefficient changes the zero phase value contour locations across the wavefront. This property is critical to the operation of phase-measuring interferometers, which give not only the magnitude but also the sign ( convexity or concavity) of a wavefront under test. Piston is physically created in the interferometer by piezoelectric actuators that translate the Fizeau interferometer reference ...

Piston (subcellular Structure)
A piston (also known as a dart, prod, or tentacle) is a complex contractile organelle found in some dinoflagellates, namely the ''Erythropsidinium'' and ''Greuetodinium'' genera of the family Warnowiaceae. This group is also well known for possessing other unusually complex subcellular structures such as the ocelloid and nematocyst (dinoflagellate), nematocyst. Observations of ''Erythropsidinium'' samples reveal that the length of the piston is highly variable across specimens. The piston is known to be capable of repetitive and dramatic contractile motion; although its function is unknown, roles in locomotion, prey capture, and defense have been suggested.

Piston Valve
A piston valve is a device used to control the motion of a fluid or gas along a tube or pipe by means of the linear motion of a piston within a chamber or cylinder. Examples of piston valves are: * The valves used in many brass instruments * The valves used for pneumatic propulsion * The valves used in many stationary steam engines and steam locomotives Brass instruments Cylindrical piston valves called Périnet valves (after their inventor François Périnet) are used to change the length of tube in the playing of most brass instruments, particularly the trumpet-like members of the family ( cornet, flugelhorn, saxhorn, etc.). Other brass instruments use rotary valves, notably the orchestral horns and many tuba models, but also a number of rotary-valved variants of those brass instruments which more commonly employ piston valves. The first piston-valved musical instruments were developed just after the start of the 19th century. The Stölzel valve (invented by H ...

Gas-operated Reloading
Gas-operation is a system of operation used to provide energy to operate locked breech, autoloading firearms. In gas-operation, a portion of high-pressure gas from the cartridge being fired is used to power a mechanism to dispose of the spent case and insert a new cartridge into the chamber. Energy from the gas is harnessed through either a port in the barrel or a trap at the muzzle. This high-pressure gas impinges on a surface such as a piston head to provide motion for unlocking of the action, extraction of the spent case, ejection, cocking of the hammer or striker, chambering of a fresh cartridge, and locking of the action. History The first mention of using a gas piston in a single-shot breech-loading rifle comes from 1856, by the German Edward Lindner who patented his invention in the United States and Britain. In 1866, Englishman William Curtis filed the first patent on a gas-operated repeating rifle but subsequently failed to develop that idea further. Between 1883 ...

Walter Piston
Walter Hamor Piston, Jr. (January 20, 1894 – November 12, 1976), was an American composer of classical music, music theorist, and professor of music at Harvard University. Life Piston was born in Rockland, Maine at 15 Ocean Street to Walter Hamor Piston, a bookkeeper, and Leona Stover. He was the second of four children. His paternal grandfather was a sailor named Antonio Pistone, who changed his name to Anthony Piston when he came to Maine from Genoa, Italy. In 1905 the composer's father, Walter Piston Sr, moved with his family to Boston, Massachusetts. Walter Jr first trained as an engineer at the Mechanical Arts High School in Boston, but was artistically inclined. After graduating in 1912, he enrolled in the Massachusetts Normal Art School, where he completed a four-year program in fine art in 1916. During the 1910s, Piston made a living playing piano and violin in dance bands and later playing violin in orchestras led by Georges Longy. During World War I, he joined ...
