Abstract
A solenoid includes a coil defining an axis, an armature disposed radially inward of the coil, and a plurality of linear guides disposed at least partially between a radially inward facing surface of the coil and a radially outward facing surface of the armature. Each of the linear guides has a frictional surface area, with a dimension of the frictional surface area aligned with the axis being larger than a dimension of the frictional surface area aligned with a circumference of the coil.
