dashpot \dash"pot`\, dash-pot \dash-pot\(d[a^]sh"p[o^]t`), n.
(Mach.)
a mechanical damping device containing a piston that moves in
a fluid-filled chamber to serve as a pneumatic or hydraulic
cushion for a falling weight, as in the valve gear of a steam
engine, to prevent shock.
[1913 Webster + WordNet 1.5]

Note: It consists of a chamber, containing air or a liquid,
in which a piston (a), attached to the weight, falls
freely until it enters a space (as below the openings,
b) from which the air or liquid can escape but slowly
(as through cock c), when its fall is gradually
checked.

Note: A cataract of an engine is sometimes called a dashpot.
