Piston   Listen
noun
Piston  n.  (Mach.) A sliding piece which either is moved by, or moves against, fluid pressure. It usually consists of a short cylinder fitting within a cylindrical vessel along which it moves, back and forth. It is used in steam engines to receive motion from the steam, and in pumps to transmit motion to a fluid; also for other purposes.
Piston head (Steam Eng.), that part of a piston which is made fast to the piston rod.
Piston rod, a rod by which a piston is moved, or by which it communicates motion.
Piston valve (Steam Eng.), a slide valve, consisting of a piston, or connected pistons, working in a cylindrical case which is provided with ports that are traversed by the valve.

"Piston" Quotes from Famous Books



... sharp and you are fond of engines, and like to "pat" them, as I do, you will notice that the cranks and piston-rods work outside the wheels, not between them, and underneath the boiler, as in the Great Western engines. You will have just time to look at the wheels and the name when the man on the platform will wave his flag, and the "Irishman" will start very gently. As ...

The piston- rods of the engines so regularly coming up from below, to look (as well they may) at the bright weather, and so regularly almost knocking their iron heads against the cross beam of the skylight, and never doing it!

... providing a heavy charge of compressed air compels the attachment to the buoy of a tube thirty-two feet or more deep, which reaches straight down into the water. The sea rising and falling in this, as the buoy tosses on the waves, acts as a sort of piston, driving out the air through the whistle, as the water rises, admitting more air ...

... due to the compression and decompression of the granular carbon between the electrodes, there exists another action due to the agitation of the granules as the chamber is caused to vibrate by the sound waves. In other words, in addition to the ordinary action, which may be termed the piston action between the electrodes, it is claimed that the general shaking-up effect of the granules when the chamber vibrates produces an added effect. Certain it is, however, that transmitters of this general type are very efficient and have proven ...

... centuries of time, condescending to turn the restless wheels of man's machinery! When the expansive burst of the vapour confined within the cylinder of the condensing steam-engine thrusts upwards the piston-rod with its mighty beams, it is simple weight—the weight of the superincumbent transparent atmosphere—that crushes the metal back with antagonistic force. When particles of water have been sublimated into the air ...

To produce a stream of air bunches of feathers or other soft substance, being fastened to long handles, are worked up and down in the upright tubes, like the piston of a pump. These, when pushed downwards, force the air through the small horizontal tubes, and, by raising and sinking each alternately, a continual current or blast is kept up; for which purpose a boy is usually placed on a high seat or stand. I cannot retrain from ...

This arrangement is also available when the air pressure is high and great power is required for ...

The steam in the cylinder of a steam-engine, after having lifted the weight of the piston, contains just as much heat as it did before leaving the boiler,—minus only the loss by radiation. Yet in the low-pressure engine we turn the steam, after having performed its office, into a condensing-apparatus, where the heat is in a manner annihilated; and in the ...

Thus, if he encloses a portion of gas in a cylinder and drives a piston down against it, he is virtually aiding cohesion by forcing the molecules closer together, so that the hold of cohesion, acting through a less distance, is stronger. What he accomplishes here is not all gain, however, for the bounding molecules, thus jammed together, come in collision with one ...
