The present invention provides a nozzle plate of an engine mount, which is embedded in the engine mount where hydro-liquid is sealed to be mounted in such a manner that the interior is divided into an upper liquid room and a lower liquid room and has a flow path formed inside to allow the sealed hydro-liquid to flow in the upper liquid room and the lower liquid room. The nozzle plate of an engine mount comprises: a lower nozzle plate having a flow path groove formed on the upper surface thereof and having a lower seating part formed thereon to protrude with a height that is higher than the bottom surface of the flow path groove; an upper nozzle plate coupled to the lower nozzle plate to form a flow path by covering the flow path groove and having an upper seating part formed to protrude downward; and a membrane mounted to be engaged between the lower seating part and the upper seating part. At least two perforated holes allowing entering and exiting of a hydro-liquid are formed on each of the lower nozzle plate and the upper nozzle plate to allow pressure of the hydro-liquid to be applied to the upper and lower surfaces of the membrane. In the present invention having the above-described structure, the pressure of the hydro-liquid is dispersed and applied to several parts of the membrane through a plurality of perforated holes such that an excessive vertical movement of the membrane can be suppressed, and pressure concentration of the hydro liquid is prevented, thereby increasing durability.

    본 발명은, 하이드로액이 봉입된 엔진마운트에 내장되되 상측액실과 하측액실로 내부를 구획하도록 장착되며, 봉입된 하이드로액이 상측액실과 하측액실을 유동하도록 내부에 유로가 형성된 엔진마운트의 노즐판에 있어서, 상면에 유로홈이 형성되고 상기 유로홈의 바닥면 보다 높게 돌출되도록 하부안착부가 형성된 노즐하판;과 상기 유로홈의 위를 덮어 유로를 형성하도록 노즐하판에 결합되며, 아랫쪽으로 돌출되도록 상부안착부가 형성된 노즐상판; 및 하부안착부와 상부안착부 사이에 맞물리도록 장착된 멤브레인;을 포함하고, 멤브레인의 상면 및 하면으로 하이드로액의 압력이 작용할 수 있도록 상기 노즐하판과 노즐상판에는 하이드로액이 출입하는 타공홀이 적어도 두 개 이상씩 각각 형성된다. 상기와 같은 구성을 갖는 본 발명은, 다수 개의 타공홀을 통해 하이드로액의 압력이 멤브레인 여러 부분에 분산되어 가해지므로 멤브레인의 과다한 상하거동을 억제할 수 있고 하이드로액의 압력 집중을 방지하여 내구성능을 증대시킬 수 있다.
