ABSTRACT:
A linear screw actuator including, an outer housing which is fixed in use, an electric motor within the housing, the motor including a hollow rotatable output shaft, a rotatable but axially fixed nut driven by said output shaft, an elongate hollow axially translatable output member, said output member extending within said output shaft of said motor and cooperating with said rotatable nut, and, an elongate anchor member secured against rotation relative to said housing and extending within said output member, said anchor member cooperating with said output member to hold said output member against rotation whereby rotation of said nut relative to said output member causes axial translation of said non-rotatable output member relative to the housing.
