Abstract
A solenoid bumper mechanism wherein a resilient means absorbs a proportion of the kinetic energy of a shaft moving within the solenoid, and a nonresilient means which causes the shaft to terminate its movement at a fixed point. The mechanism provides shaft movement of repeatable precise distances and also does not interfere with the magnetic field created by the solenoid body.
