Abstract
An electromagnetic actuator having an actuating permanent magnet and a simplified construction is provided. The electromagnetic actuator includes a housing having a base, a side wall extending from the base to a termination plane, and a substantially open side. The electromagnetic actuator further includes a pole piece arranged within the housing, a wire coil positioned around the pole piece and arranged within the housing, and a permanent magnet coupled to the pole piece by a spring and moveable between a first position and a second position. An actuation position of the permanent magnet between the first position and the second position is proportional to a magnitude of a current applied to the wire coil.

An electromagnetic actuator comprising:
- a housing including a base, a side wall extending from the base to a termination plane, and a substantially open side;
- a pole piece arranged within the housing;
- a wire coil arranged within the housing, wherein the pole piece is arranged within the wire coil;
- a permanent magnet moveable between a first position and a second position, and every position between the first position and the second position;
- and
- wherein every position of the permanent magnet between the first position and the second position is proportional to a magnitude of a current applied to the wire coil.
A control valve comprising:
- an electromagnetic actuator including:
- a housing including a base, a side wall extending from the base to a termination plane, and a substantially open side;
- a pole piece arranged within the housing;
- a wire coil positioned around the pole piece and arranged within the housing;
- a permanent magnet coupled to the pole piece by a spring and moveable between a first position and a second position, and every position between the first position and the second position;
- and
- wherein every position of the permanent magnet between the first position and the second position is proportional to a magnitude of a current applied to the wire coil;
- a valve body including at least one work port;
- and
- a valve spool slidably received within the valve body and coupled to the permanent magnet for actuation therewith.
