Engine mount

The invention relates to an engine mount including: an insulator disposed in a case which has a liquid chamber; an orifice plate dividing the liquid chamber into an upper liquid chamber and a lower liquid chamber, the orifice plate dividing the upper liquid chamber together with the insulator and having an orifice therein for inducing flow of fluid between the upper liquid chamber and the lower liquid chamber; and a diaphragm disposed under the orifice plate inside the case, the diaphragm dividing the lower liquid chamber together with the orifice plate. The orifice plate has a direct passagefor enabling the upper liquid chamber and the lower liquid chamber to directly communicate with each other so that liquid flows between the upper liquid chamber and the lower liquid chamber, and includes an opening/closing piston for opening or closing the direct passage. 本发明涉及种发动机悬置，包括：绝缘体，设置在具有液体室的壳体中；孔板，将液体室分成上部液体室和下部液体室，孔板与绝缘体起分隔上部液体室，并在孔板中具有孔，用于引导流体在上部液体室和下部液体室之间流动；以及隔膜，在壳体内设置在孔板下方，隔膜与孔板起分隔下部液体室。孔板具有用于使上部液体室和下部液体室能够彼
