PURPOSE: A liquid-filled engine mount is provided to prevent noise occurrence and to maintain agreeable ride comfort by cutting off the flow of working fluids to make a membrane pressed on an orifice upper plate even if large displacement engine vibration occurs. CONSTITUTION: A liquid-filled engine mount contains a damping chamber(D) formed to make an inside space filled with liquid by coupling a main rubber(300) and a diaphragm(500) to upper and lower parts of a main pipe(400), and an orifice unit(600) and a membrane(700) installed to the inside of the damping chamber to divide the damping chamber into an upper chamber(U) and a lower chamber(L), wherein the orifice unit is provided with a liquid flow hole(611) at the center to make the upper chamber and the lower chamber to be communicated, and the membrane is installed to open and shut the liquid flow hole according to the displacement of the diaphragm.
