Abstract
A screw actuator comprises a housing (1), a screw mechanism (4) with a nut (6) and a screw (5), as well as a motor (7) which is drivingly connected to the screw. The screw (6) is rotatably and translatably supported with respect to the nut (5), which is fixed with respect to the housing (1). The screw engages a translatable, non rotatable actuating head (29) through a swivel connection. The swivel connection comprises a pair of conformed surfaces (41, 42) having a common rotational axis of symmetry which is aligned with the axis of the screw mechanism.
