A dashpot is a mechanical device, a damper which resists motion via viscous friction. The resulting force is proportional to the velocity, but acts in the opposite direction, slowing the motion and absorbing energy. It is commonly used in conjunction with a spring (which acts to resist displacement). The diagram symbol for a dashpot is: . Damper is a traditional Australian outback food prepared by swagmen, drovers and other travellers. ... Friction is the force that opposes the relative motion or tendency of such motion of two surfaces in contact. ... The velocity of an object is simply its speed in a particular direction. ...

Types

Two common types of dashpots exist - linear and rotary. Linear dashpots are generally specified by stroke (amount of linear displacement) and damping coefficient (force per velocity). Rotary dashpots will have damping coeffients in torque per angular velocity.

A less common type of dashpot is an eddy current damper, which uses a large magnet inside of a tube constructed out of a non-magnetic but conducting material (such as aluminum or 316 stainless steel). Like a common viscous damper, the eddy current damper produces a resistive force proportional to velocity. This article or section does not cite its references or sources. ...

Applications

dashpot in a Stromberg carburetor

A dashpot is a common component in a door closer to prevent it from slamming shut. A spring applies force to close the door and the dashpot, implemented by requiring fluid to flow through a narrow channel between reservoirs (often with a size adjustable by a screw), slows down the motion of the door.

Dashpots are commonly used in dampers and shock absorbers. The hydraulic cylinder in an automobile shock absorber is a dashpot. A shock absorber is a mechanical device designed to smooth out or damp a sudden shock impulse and dissipate kinetic energy. ...
