Abstract
In a preferred embodiment, an actuator, including: a shaft (,); a solenoid (,), having a coil (,) and a core (,), disposed at a first selected position on the shaft, with the core being fixedly attached to the shaft such that energization of the coil will cause the shaft to move axially; and a rotary motor (,), having a stator (,) and a rotor (,), disposed at a selected second position on the shaft, with the shaft passing through the rotor, an external surface of the shaft and an internal surface of the rotor having complementary engaging surfaces such that rotation of the rotor will cause rotation of the shaft and axial motion of the shaft will be isolated from the rotor.
