Piston
n 1: United States neoclassical composer (1894-1976) [synonym:
{Piston}, {Walter Piston}]
2: mechanical device that has a plunging or thrusting motion
[synonym: {piston}, {plunger}]

Piston \Pis"ton\, n. [F. piston; cf. It. pistone piston, also
pestone a large pestle; all fr. L. pinsere, pistum, to pound,
to stamp. See {Pestle}, {Pistil}.] (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.
[1913 Webster]

{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.
[1913 Webster]
