ABSTRACT:
A proportional solenoid consisting of a stationary pole piece of ferromagnetic material which has a radially externally facing frusto-conical section surrounding a cylindrical recess in the stationary pole piece. Both the stationary pole piece and armature are fitted into the bore of a guide tube. Thus, the bore of the guide tube provides the required concentricity between the movable armature and the stationary pole piece. The movable armature is provided with an integral reduced diameter cylindrical nose that is complimentary to the cylindrical recess of the stationary pole piece.
