PURPOSE: A hydro engine mount is provided to clearly reduce vibration in a low frequency band by passing a working fluid only through an orifice fluid passage and preventing a membrane from varying in the low speed driving of a vehicle. CONSTITUTION: A hydro engine mount comprises an outdoor air access space unit(80) and a valve unit(90). The outdoor air access space unit comprises the orifice body(62) of an orifice unit(60) and a membrane(70). The outdoor air access space unit is not connected with an orifice fluid passage(63), an upper fluid chamber(U), and a lower fluid chamber(L). The valve unit is mounted on the tubular unit(81) of a vent pipe. The valve unit closes in the low speed driving of a vehicle and opens in the high speed driving of the vehicle. |
