Abstract
This is a hydraulic anti-vibration mount intended to be interposed between a vehicle body and an engine and in particular comprising an armature which can be secured to the body, a head which can be secured to the engine, a thick frustoconical wall linking a circular bearing surface of the armature to the head and defining with the latter a working chamber, and a diaphragm defining with the armature a compensation chamber which communicates with the chamber via a restricted passage. An active attenuation device is also provided, the device comprising a piston immersed in the working chamber, a member for exciting this piston and an electronic circuit for controlling this excitation member. The armature forms on the one hand a double pan constituting the ends, arranged side by side, of the two chambers and on the other hand a housing containing side by side the excitation member and its electronic control circuit.
