Description: |
| A reciprocatory armature type igniter conventionally uses a cam that forces the armature into engagement with a magnetic core; the movement is independent of engine speed and thus the spark intensity is independent of speed, which is a major advantage of this type of igniter. This patent is a companion to patent 1,307,342, and aims to further reduce audio noise by providing resiliency at the end of the reciprocating motion by using springs. |
