Abstract
A solenoid valve actuator includes a coil bobbin having a coil disposed therein and a bushing body receiving aperture. A flux plate is connected to a first end of the coil bobbin and includes a flux plate surface area. A bushing is positioned between the flux plate and the coil bobbin. The bushing includes a flange portion having a flange area substantially equal to the flux plate surface area, and a body portion integrally joined to the flange portion and extending substantially perpendicular to the flange portion. An armature is slidably received within the receiving aperture of the bushing body portion.
Claims36
A solenoid actuator bushing disposable between an armature and a coil bobbin, the bushing comprising:
- a flange portion having a flange area substantially equal to an area of a solenoid flux plate;
- and
- a body portion disposed perpendicular to the flange portion.
A valve solenoid operator, comprising:
- a flux plate having a flux plate surface area;
- a bushing, including:
- a flange portion disposed in contact with the flux plate, the flange portion having a flange area substantially equal to the flux plate surface area;
- and
- a body portion extending substantially perpendicular to the flange portion;
- and
- an armature slidably disposed within the body portion and operable to displace upon exposure to an electromagnetic flux field;
- wherein the flange area of the flange portion operably increases the electromagnetic flux field.
A solenoid valve actuator, comprising:
- a bushing, including:
- a rectangular-shaped flange portion having a flange area defining a flux plate surface area;
- and
- an oblong-shaped body portion integrally joined to the flange portion and extending substantially perpendicular to the flange portion;
- and
- an oblong-shaped armature slidably received within the body portion;
- wherein an electromagnetic flux coupled through the armature is increased by the flange area of the flange portion.
A solenoid valve actuator, comprising:
- a coil bobbin having a coil disposed therein and a bushing body receiving aperture;
- a flux plate connectable to a first end of the coil bobbin, the flux plate having a flux plate surface area;
- a bushing positionable between the flux plate and the coil bobbin, the bushing including:
- a flange portion having a flange area substantially equal to the flux plate surface area;
- and
- a body portion integrally joined to the flange portion and extending substantially perpendicular to the flange portion;
- and
- an armature slidably received within the body portion of the bushing.
A method for creating a solenoid actuator, the actuator having at least a bushing including a bushing flange and a bushing body extending perpendicularly from the bushing flange, a flux plate having a flux plate area and a bushing body receiving aperture, and an armature receivable within the bushing body, the method comprising:
- sizing the bushing flange having an area substantially equal to the flux plate area;
- creating an armature aperture through the bushing flange, the armature aperture co-axially alignable with a corresponding flux plate armature aperture;
- slidably inserting the armature into the bushing body through the armature aperture;
- and
- sliding the bushing body into the bushing body receiving aperture until the bushing flange abuts the flux plate, the bushing flange operable to substantially completely cover the flux plate with the armature aperture co-axially aligned with the flux plate armature aperture.
