Solenoid housing and method of making the same

A method of providing a solenoid housing, comprising the steps of:

• providing a cylinder of malleable material having a first part and a second part, said first part having a first-part perimeter and said second part having a second-part perimeter;
• reducing a size of the first-part perimeter to be less than a size of the second-part perimeter;
• compressing at least a portion of said second part in a direction towards said first part to produce a flattened disk;
• providing said cylinder of malleable material with a non-magnetic region;
• extending a bore from said first part toward said second part to at least a distance beyond said non-magnetic region;
• and
• providing a cup around said cylinder of malleable material.

A solenoid housing comprising:

• a center pole having a first end and a second end;
• a flattened disk at said second end of said center pole;
• a bore extending from a first end in a direction towards said second end;
• a non-magnetic region on said center pole;
• a protrusion on said second end, said protrusion having a protrusion perimeter and a protrusion end having a protrusion-end perimeter;
• wherein said center pole, flattened disk, and protrusion are formed of a one-piece construction;
• and
• a cup having a recess for accepting said protrusion, wherein said recess has a recess perimeter which is larger than said protrusion perimeter but smaller than said protrusion-end perimeter.
