Abstract
A push rod for use in a vehicle with an electro-mechanical actuator system, which has an armature and a core, selectively moves an object of the vehicle as the armature moves between first and second positions. The push rod includes a body and a flange extending radially away from the body to a perimeter surface. The flange has an engagement surface defining a channel. The perimeter surface defines a perimeter opening at the channel for facilitating flow of a fluid into the channel between the engagement surface and the core for preventing a vacuum therebetween. A method of manufacturing the push rod includes the steps of providing a material, and drawing and swaging the material to produce the push rod.
