Abstract: An engine mount assembly comprises a rigid dome-shaped cover secured to the vehicle body or chassis. The cover supports internal rubber elements which in turn support rigid facing jaws. A damping module comprising two bellows chambers and an assembly of two valve elements is inserted in a unit, together with a valve arrangement. A bolt secured to the engine of the vehicle passes through the valve elements and holds the damping module in position and transmits engine vibrations to the damping module. Hydraulic fluid in the chambers is thus forced through a helical conduit which contains a restriction for damping the fluid movement and thus the vibrations. At higher vibration frequencies, valve flaps vibrate causing alternate small compression and expansion of the chambers and thus damping of the vibrations.
