piston
in an internal-combustion engine

pis·ton

 (pĭs′tən)
n.
1. A solid cylinder or disk that fits snugly into a larger cylinder and moves under fluid pressure, as in a reciprocating engine, or displaces or compresses fluids, as in pumps and compressors.
2. Music A valve mechanism in brass instruments for altering the pitch.

[French, from Italian pistone, pestone, large pestle, from pestare, to pound, crush, from Late Latin pistāre, frequentative of Latin pīnsere, pīnsāre.]

piston

(ˈpɪstən)
n
(Automotive Engineering) a disc or cylindrical part that slides to and fro in a hollow cylinder. In an internal-combustion engine it is forced to move by the expanding gases in the cylinder head and is attached by a pivoted connecting rod to a crankshaft or flywheel, thus converting reciprocating motion into rotation
[C18: via French from Old Italian pistone, from pistare to pound, grind, from Latin pinsere to crush, beat]

pis•ton

(ˈpɪs tən)

n.
1. a disk or solid cylinder moving within a longer cylinder and exerting pressure on, or receiving pressure from, a fluid or gas.
2. a pumplike valve used to change the pitch in a cornet or the like.
[1695–1705; < French < Italian pistone piston, a learned alter. of pestone large pestle =pest(are) to pound (variant of Medieval Latin pistare, derivative of Latin pīstus, past participle of pīnsere to pound) + -one augmentative suffix]

piston
The fuel-air mixture in the left-hand chamber expands when ignited by the spark plug, pushing the piston down and turning the shaft to which it is attached. The turning shaft drives the piston in the right-hand cylinder upward. It will then be pushed down in the same way when the fuel-air mixture enters that chamber and is ignited. The alternating action of the two pistons keeps the shaft turning.

pis·ton

(pĭs′tən)
A solid cylinder or disk that fits snugly into a hollow cylinder and moves back and forth under the pressure of a fluid, as in many engines, or moves or compresses a fluid, as in a pump or compressor.
