Integrated power relay for electric starter motor

摘要

A starter relay disposed in the housing of an electric starter of an internal combustion engine. The starter relay has a pair of stationary contact members electrically connected by a movable bar contact. The movable bar contact is mechanically linked to an annular relay armature which is axially displaceable by an annular electromagnetic coil. A coil spring produces a force biasing the relay armature away from the electromagnetic coil and the movable bar contact away from the contact members. In the preferred embodiment the operation of the power relay is transparent to the operation of the starter drive mechanism and the annular electromagnetic coil is the electromagnetic coil of the existing started drive mechanism.
