Abstract

The system controls a support (1) interposed between an engine (2) and the structure (3) of an automobile vehicle comprising a work chamber (7) and an expansion chamber (8) filled with liquid and interconnected by a passageway (9), in which the work chamber (7) is partly defined by an elastic movable wall (10) comprising a push member (11) with which cooperates a driving device (12) for applying to this partition wall movements in such manner as to produce in the chamber (7) pressure forces synchronous with the harmonics of the vibrations of the operation of the engine. The system is characterized in that the driving device comprises an electric motor (12) connected to the push member (11) by actuating means (16) actuating in accordance with a reciprocating linear motion, and the system comprises means (22) for controlling the electric motor (13) in speed and angular position by a signal of the operating cycle of the engine.
