Electrically operated solenoid having an adjustable actuator pin length

An electrically operated solenoid for controlling a mechanical device, comprising:

• a bobbin defining an interior region extending along an actuation axis;
• an energizing coil wire wound about an exterior region of said bobbin;
• a plunger adapted for reciprocating movement along said actuation axis, said plunger defining a first passage extending therethrough, said first passage including a threaded portion;
• a core at least partially disposed within said interior region of said bobbin and defining a second passage extending therethrough generally aligned with said first passage in said plunger;
• an actuator pin having a first portion disposed within said first passage in said plunger and a second portion extending through said second passage in said core for engagement with the mechanical device, said actuator pin engaged with said plunger such that said reciprocating movement of said plunger correspondingly displaces said actuator pin through said second passage in said core along said actuation axis to control operation of the mechanical device;
• and
• an adjustment screw threadingly engaged within said threaded portion of said first passage in said plunger and engaged with said first portion of said actuator pin, said adjustment screw being threadable along said threaded portion of said first passage to correspondingly adjust a position of said actuator pin relative to said plunger along said actuation axis.

An electrically operated solenoid for controlling a mechanical device, comprising:

• an outer housing extending along an actuation axis between a first end and an opposite second end;
• a coil assembly defining an interior region having a length extending along said actuation axis;
• a plunger adapted for reciprocating movement along said actuation axis and defining a first passage extending therethrough;
• an actuator pin having a first end portion disposed within said first passage in said plunger and a second end portion extending along said interior region of said coil assembly for engagement with the mechanical device adjacent said second end of said housing, said actuator pin engaged with said plunger such that said reciprocating movement of said plunger correspondingly displaces said actuator pin along said actuation axis to control operation of the mechanical device;
• and
• an adjustment member extending into said first passage in said plunger adjacent said first end of said housing and into engagement with said first portion of said actuator pin, said adjustment member displaceable along said first passage in said armature member to correspondingly adjust a position of said actuator pin relative to said plunger along said actuation axis.
