First Claim
Patent Images
1. A method for producing a solenoid housing comprising:
- providing a single piece ferromagnetic armature housing;
forming a groove around the perimeter of the housing;
filling the groove with a non-ferromagnetic material such that the non-ferromagnetic material forms an annular non-ferromagnetic piece that spans the entire groove; and
removing material from the armature housing such that two ferromagnetic pieces are separated by the non-ferromagnetic piece within the single piece ferromagnetic armature housing.

Abstract
An improved method for manufacturing a solenoid. The method includes the step of providing a single piece ferromagnetic housing. The method also includes the step of forming a groove around the perimeter of the housing. The method further includes the step of filling the groove with a non-ferromagnetic material such that the non-ferromagnetic material forms an annular ferromagnetic piece that spans the entire groove in the housing. Finally, the method includes the step of removing an inside portion of the housing such that two separate ferromagnetic pieces are formed joined by the non-ferromagnetic piece.
