Abstract: A high speed axial-type printing solenoid includes a rebound and energy absorbing arrangement which employs a block of energy-absorbing "dead" elastomeric material held in a partially compressed state by an impact plate. The impact plate is mounted to engage and position the plunger or armature at a rest position and to transmit impact forces to the partially compressed block of elastomeric material.

Abstract: A print wire solenoid for high-speed operation is made with two major components or subassemblies. The first is a plastic injected unitary bobbin or stator assembly which incorporates a core ring and a core, and a stator which forms a bobbin for receiving an electric coil. The parts in the stator are positioned and molded to a datum surface. The second major subcomponent is a unitary armature assembly which incorporates an armature, a retraction spring, and a print wire, all anchored to a plastic body. These parts are likewise positioned with respect to a datum surface. The stator assembly and armature assembly are retained within a drawn metal case, and a rebound disc is positioned within the case and locates the datum surface of the armature assembly in the same plane as the datum surface of the stator assembly so as to define an accurate working air gap.
