dashpot

[′dash‚pät]
(mechanical engineering)
A device used to dampen and control a motion, in which an attached piston is loosely fitted to move slowly in a cylinder containing oil.

dashpot

A mechanical, hydraulic, or pneumatic damper used to cushion or slow down mechanical movement by restricting the flow of viscous fluid. Dashpots are used in shimmy dampers and in some power control systems, where they come into operation at high speeds to prevent pilot-induced oscillations. See dashpot throttle.

The spring represents the elastic solid-like behavior where Hooke's law is valid (F = E[epsilon] where F is load or force, E is elastic modulus and [epsilon] is strain), whereas the dashpot represents the time-dependent, viscous liquid-like behavior where Newton's law is valid (F = [eta](d[epsilon]/dt) where [eta] is the viscosity or damping constant).
