DIFFERENTIAL LEVER ACTUATOR INCLUDING DIFFERENTIALLY FORCE-TRANSMITTING MEMBERS WHICH ARE NOT LIABLE

摘要

The differential lever actuator, which is designed to avoid the deformation of differential force-transmitting members, comprises transmission members (41,42) for differentially transmitting oppositely sensed angular displacements from first and second weight points (P1, P3) of first and second lever members (31,32) to first and second predetermined points (P2, P4) of a differential lever member (43). A distance (h) between midpoints (S,T), between the first weight (P1) and predetermined points (P2) and between the second weight (P3) and predetermined points (P4) is kept constant irrespective of the angular displacements.
