Abstract:
An electrically operated solenoid for controlling a mechanical device, comprising:a coil assembly defining an interior region extending along an actuation axis; an armature member adapted for reciprocating movement along said actuation axis and defining a first passage extending therethrough; a pole piece member at least partially disposed within said interior region of said coil assembly and defining a second passage extending therethrough generally aligned with said first passage in said armature member; a shaft member having a first portion disposed within said first passage in said armature member and a second portion extending through said second passage in said pole piece member for engagement with the mechanical device, said shaft member engaged with said armature member such that said reciprocating movement of said armature member correspondingly displaces said shaft member through said second passage in said pole piece along said actuation axis to control operation of the mechanical device; and an adjustment member extending into said first passage in said armature member and into engagement with said first portion of said shaft member, said adjustment member displaceable along said first passage in said armature member to correspondingly adjust a position of said shaft member relative to said armature member along said actuation axis.
