BIDIRECTIONAL PISTON WITH GEARED LENGTHENER ELECTRICALLY DRIVEN BY MOTOR EQUIPPED WITH A REDUCER

摘要

The invention relates to two homocentric power-driven pistons E1, E2 extended by a worm gear, the one piston E1 being extended to the one direction and the other E2 to the opposite one. The advantage of the invention is that the use of this bi-directional piston allows anyone to achieve from the same source of movement two opposite movements.
