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. [1913 Webster]

Note: A cataract of an engine is sometimes called a dashpot. [1913 Webster]
