Damper winding. Bars and rings of the damper (amortisseur) winding of an AC generator (General Electric, early 20th century). Note the gaps in the cage along the quadrature axes. The damper winding (also amortisseur winding[1]) is a squirrel-cage -like winding on the rotor of a typical synchronous electric machine.
Harmonic balancer lower pulley on a four-cylinder engine. A harmonic damper is a device fitted to the free (accessory drive) end of the crankshaft of an internal combustion engine to counter torsional and resonance vibrations from the crankshaft. This device must be an interference fit to the crankshaft in order to operate in an effective manner.

Allen & Co was founded in 1880 by William Henry Allen as a manufacturer of centrifugal pumps and steam engines in York Street, Lambeth, London. [1] [2] Electric light generating machinery followed with the support of Gisbert Kapp.
A dashpot, also known as a damper[citation needed], is a mechanical device that resists motion via viscous friction. [1] The resulting force is proportional to the velocity, but acts in the opposite direction, [2] slowing the motion and absorbing energy. It is commonly used in conjunction with a spring. The process and instrumentation diagram ...

Superheater viewed from the smokebox. Top centre is the superheater header, with pipes leading to cylinders. Tubes below feed steam into and out of the superheater elements within the flues. The stack and the damper have been removed for clarity. In steam locomotive use, by far the most common form of superheater is the fire-tube type.
A gas spring consists of a sealed cylinder filled with a charge of high-pressure [4] gas, a piston rod attached to a piston with a sliding seal, and some oil. [1] The piston (or the cylinder wall) contains a number of channels that allow the gas to transfer between the lower chamber (between the piston and the closed end of the cylinder) and the upper chamber (between the piston and the head ...
