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



... Understand, this was the first time we went into Loando. I have learned that wretched hole well enough since. And it was as we were running out of Loando, that, in reversing the engine too suddenly, lest we should smash up an old Portuguese woman's bum-boat, that the slides or supports of the piston-rod just shot out of the grooves they run in on the top, came cleverly down on the outside of the carriage, gave that odious g-r-r-r, which I can hear now, and then, dump,—down came the whole weight of the walking-beam, ...

Did you ever happen to see that most soft-spoken and velvet-handed steam-engine at the Mint? The smooth piston slides backward and forward as a lady might slip her delicate finger in and out of a ring. The engine lays one of ITS fingers calmly, but firmly, upon a bit of metal; it is a coin now, and will remember ...

I am told that if you construct a perfectly fitted engine—the piston fitting the cylinder with absolute accuracy and the axles their sockets with no space between, &c.—it will not work, but be a lifeless mass of iron. There must be enough play between the vital parts to allow of some movement; "dither" is, I believe, the Scotch word for it. The piston must ...

... E.D. Farcot decided to study out one for himself. Almost from the very beginning of his researches in this direction, he adopted the Woolf system, which is one that permits of great variation in the expansion, and one in which the steam under full pressure acts only upon the small piston. There are many types of this engine in use, all of which present marked defects. In one of them, the large cylinder is arranged directly over the small one so as to have but a single rod for the two pistons; and the two cylinders have then one bottom in common, which is furnished ...

... valve passes below the bottom lip of the groove, the steam is cut off from the space between it and the main valve, which is fitted with packing rings and works over a latticed port. This port opens directly into the cylinder. The exhaust takes place chiefly through a port uncovered when the piston is approaching the end of its stroke. The remaining vapor left in the cylinder is exhausted under the lower edge of the main valve, until cushioning commences, and the steam from both upper and lower ports is discharged into the exhaust box shown in Fig. 2.

What he accomplishes here is ...

An air pump, driven by steam, exhausts the air from a cylinder in which a piston moves; this cylinder is laid the whole length of the road, and the piston is connected to a car above, so that, as the piston moves forward on the exhaustion of the air in front of it, the car is also carried forward.

But Bud Lee's pain-racked body clung on, his thumb and fingers sank and sank deeper into the corded muscles of the heaving throat, crooked like talons, white ...

... continued nearly in the same state for two or three years more, but she always found herself better if she left her own house for any length of time. At length it occurred to me, that though the pump was a wooden one, the piston might work in lead. I therefore ordered the pump rods to be drawn up, and upon examination with a magnifying glass, found the leather of the piston covered with an infinite number of very minute shining particles of lead. Perhaps in this instance the metal was so minutely ...

... much the same thing—an easily portable substance, which could be decomposed electrically by wind or water power, and which would then recombine and supply force, either in intermittent thrusts at a piston, or as an electric current, would be infinitely more convenient for all locomotive purposes than the cumbersome bunkers and boilers required by steam. The presumption is altogether in favour of the possibility of such substances. Their advent will be the beginning ...

... movements of the heel with those of the crank-pin of an engine. One serves as the lever by which the gastrocnemius helps to propel the body; the other serves the same purpose in the propulsion of a motor cycle. On referring to Fig. 7, A, the reader will see that the piston-rod and the crank-pin are in a straight line; in such a position the engine is powerless to move the crank-pin until the flywheel is started, thus setting the crank-pin in motion. Once started, ...

Boulton and Watt for the "Clermont" were precisely of the same dimensions as those in the "Charlotte Dundas," with the exception of two inches more diameter in the piston; and the patent of Fulton dates from 1809—twenty years after Symington had propelled a boat by steam on Lake Dalswinton, and eight years after he had himself taken sketches of Symington's engines in the ...

... the force of chemical affinity breaks up the chemical composition of the coal, how the heat thus liberated is applied to the water to vapourize it; how the vapour is collected in the boiler under pressure; how this pressure is applied to the piston in the cylinder, and how this finally results in the revolution of the fly-wheel. It is true that we do not understand the underlying forces of chemism, etc., but these forces certainly exist and are the foundation of science. But the mechanism of the engine is intelligible.

Their generally long bills have been spoken of by some naturalists as tubes into which they suck the honey by a piston-like movement of the tongue; but suction in the usual way would be just as effective; and I am satisfied that this is not the primary use of the tongue, nor of the mechanism which enables it to be exerted to a great length beyond the ...

... had invented the double-acting steam-engine, but few had been manufactured, and those in common use were "atmospheric" engines, known as "Newcomen's" engines. A pumping-engine had a long, vertical cylinder, with arrangements for admitting steam at the top. The weight of the piston, piston-rod, and pump-rod, which ran down a shaft to the lowest point in the mine, being balanced by a counter-weight on a sort of well-sweep, the steam, admitted by hand, forced the piston to the bottom of the cylinder. The steam was then shut off, and a spray of water was turned ...

... with "time"—no matter what time is—is able to produce, by transformation or by drawing on other sources of energy, new energies unknown to nature. Thus the solar energy transformed into coal is, for instance, transformed into the energy of the drive of a piston, or the rotary energy in a steam engine, and so on. It is obvious that no amount of chemical energy in food can account for such an energy as the time-binding energy. There is only one supposition left, namely, that the time-binding apparatus has a source ...

Suppose a horizontal section of the smaller cylinder to measure one square inch, that of the larger to be one hundred square inches. A weight of one pound on the smaller piston will balance a weight of one hundred pounds on the larger. If a downward pressure of one pound be exerted on the smaller piston, the larger piston will exert an upward pressure of one hundred pounds. Conversely, a downward pressure of one hundred pounds, exerted ...

Her engineer, Mr. Campbell, was in the act of giving some final touches to the machinery, when his leg was caught between the piston-rod and frame of one of the oscillating engines, with such force as to bend the rod, which was an inch and a quarter in diameter and about eight inches long, and break its cast-iron frame, five-eighths of an inch in thickness. The most remarkable fact in this case is, that the limb, though ...

The great bulb which buoys up the whole mass rises and falls with the motion of the waves, carrying the tube up and down with it, thus establishing a piston-and-cylinder movement, the water in the tube acting as an immovable piston, while the tube itself acts as a moving cylinder. Thus the air admitted through valves, as the buoy rises on the wave, into that ...
