摘要
The dashpot of this invention includes the substantially cylindrical cylinder in which travels a piston having a diameter slightly less than that of the interior of the cylinder. A liquid or modified liquid defines the medium in the cylinder in which the piston is adapted to travel. The flow ingenerated in the cylinder is predominantly a pressue flow with the shear flow being relative insignificant. The flow is also at sufficiently high Reynolds numbers such that inertial effects are present. The device of the prsent invention operates in the lubrication regime whereby relatively small timers are capable of providing time delays of up to several seconds or more.
