Abstract
A fluid filled engine mount including: a pressure-receiving chamber and an equilibrium chamber connected via an orifice passage tuned to a frequency band of engine idling vibrations; an orifice control member operable by means of negative pressure exerted from an external space so as to restrict flow of the fluid through the orifice passage when an absolute value of the exerted negative pressure is greater than a predetermined value; and a negative pressure conduit of direct connection type, adapted to always introduce negative pressure available from an air intake port of an internal combustion engine to the orifice control member.
