Abstract
An engine mount system includes multiple liquid-filled engine mounts switchable to provide different mount characteristics by selectively introducing negative pressure or atmospheric pressure. On one of pipelines connected to the respective engine mounts for introducing the negative or atmospheric pressure into the respective engine mounts, a check valve and an orifice portion are provided in parallel. The orifice portion restricts an amount of air flowing therethrough, so that the mount characteristic of the engine mount connected to the one pipeline equipped with the check valve and the orifice portion does not undergo an abrupt change when the pressure introduced in the engine mount is switched from the negative pressure to the atmospheric pressure.
