Abstract

See full text

An electromagnetic solenoid actuator includes a ferromagnetic core body defining an axis, a winding supported by the core body, and a ferromagnetic plunger body translatable within the core body along the axis. The core body has a fixed height gap that extends about the axis and the plunger body and core body define between one another a variable height gap that extends about the axis. A first flux bypass extends through the fixed height gap and a second flux bypass extends through the variable height gap that cooperate with one another to correct the attraction force between the plunger and core body as height of the variable height gap changes.
