Abstract:
An adjustable solenoid, comprising:a) an enclosure containing a winding through which a current is passed, said winding defining an area; b) a plunger being positioned at one end of said area, said plunger having an actuating member positioned to pass through an opening in said enclosure, said plunger being configured for movement between an actuating position and a non-actuating position; c) a mechanical biasing mechanism for providing a biasing force to said plunger, said mechanical biasing mechanism being secured to said plunger at one end and a support at the other; d) a stator having a first threaded portion being engaged within a threaded opening of said enclosure, said first threaded portion and said threaded opening of said enclosure causing said stator to travel between a first position and a second position as a rotational force is applied to said stator, said first position being closer to said plunger than said second position, said stator being in a facially spaced relationship with respect to said plunger and having a second threaded portion for engaging a threaded portion of said support, said second threaded portion of said stator causing said support to travel between a first position and a second position, said second position of said support provides said mechanical biasing mechanism with a greater biasing force than said first position.
