Rotary valve actuator arrangement |
摘要 |
A rotary valve actuator arrangement including a rotary valve and an electromagnetic actuator actuating the rotary valve. The rotary valve includes a valve shaft rotatable about an axis and a valve body disposed on the valve shaft for unitary rotation therewith. The electromagnetic actuator includes two stator cores, two coils wound on the stator cores, and a rotor rotatable about the axis and including two projecting portions opposed to the stator cores. Mutually opposed surfaces of the stator cores and the projecting portions define a continuously variable area forming a magnetic path when the coil is energized.
