<p>According to the present invention, an engine mount filled with a hydro liquid comprises: an insulator mounted on a housing having a core coupled to the top thereof, and elastically deformed depending on a force applied to the core; a nozzle plate having a flow path formed therein and opened up and down to allow the hydro liquid to flow in the flow path coupled between the insulator and a diaphragm coupled to the bottom of the housing; and a piston mounted to partition an inner space between the insulator and the nozzle plate coupled to the core, and moved depending on the force applied to the core. An upper and a lower liquid chamber wherein the hydro liquid filling the engine mount flows are formed between the piston and the nozzle plate, and between the nozzle plate and the diaphragm respectively. An air chamber formed between the piston and the insulator allows air to flow thereinto or therefrom by being opened to the outside through an air channel. According to the present invention, the air and hydro liquid are used as working fluids, thereby efficiently damping more vibrations on a wider frequency domain.</p> |
