Abstract
An absorber is position on the back or opposite side of a solenoid to receive the kinetic energy of the armature. The energization of the solenoid attracts the armature to the solenoid core and upon striking the core, the kinetic energy of the armature is transferred through the core and to the absorber. The absorber is launched into flight for the purposes of dissipating the kinetic energy and returns to rest on the core without effecting the movement of the armature. The absorber dissipates the kinetic energy by transferring it to a spring means and also may dissipate the energy by means of viscous damping or the flow of fluid from one side of the absorber to the opposite side.
