  • Shifting actuator
    Patent number: 4428248
    Abstract: A shift actuator (10, 100, 200) for selectively shifting a shift member (12, 102) to one of at least two selectable operating positions is provided. The actuator includes a rotational member such as a cam (36) or scotch yoke flywheel (204) rotatably driven by a unidirectional rotational motor (26) to one of two or more selectable rotational positions, each of which rotational positions is effective to cause a single compression spring (56, 166) to urge an engagement member (64 and 66, 108) to axially move the shift member to one of the at least two selected positions.
