Vibration damping arrangement

摘要

A vacuum-operated mount for mounting an engine of a passenger or commercial motor vehicle which includes a variable volume chamber enclosed by a thick rubber encasement. The encasement is adapted to tolerate a force greater than the suspended engine under the effect of a moderated vacuum affected by controlling a connection of the variable volume chamber with two additional enclosures or chambers so as to increase or decrease a vacuum in the work chamber in order to create an accelerating force for correcting a displacement of the engine.
