An engine mount is provided that includes a nozzle plate that is mounted between an insulator and a diaphragm to divide the interior into upper and lower fluid chambers to enable the flow of hydraulic fluid between the chambers through a first flow path formed in the nozzle plate according to variation in the volume of the interior. The nozzle plate includes a second flow path and a division cup that has an upwardly protruding portion to push the diaphragm to divide the lower fluid chamber into a main fluid chamber communicating with the flow path and an auxiliary fluid chamber communicating with the second flow path. A partition is formed inside the protruding portion to form a chamber below the auxiliary fluid chamber, and an introduction/discharge aperture is formed in the partition to enable introduction or discharge of air into or from the chamber.

A vibration isolator includes a housing forming an internal cavity, an elastomeric diaphragm within the internal cavity, the elastomeric diaphragm combining with a first end of the housing to form an air spring within the internal cavity, a mechanical spring in series with the air spring within the internal cavity; a mount in series with the mechanical spring opposite the air spring, an annular elastomeric stopper between a second end of the housing and the mount, wherein the mount and the annular elastomeric stopper combine to seal the second end of the housing to form a chamber within the internal cavity between the elastomeric diaphragm and the second end of the housing, and a plate seated on the mount within the chamber.

An anti-vibration device includes: a cylinder body coupled to a vibration receiver; a support body coupled to a vibration source; an elastic body that attaches the support body to the cylinder body such that the support body is capable of moving relative to the cylinder body; a first liquid chamber sectioned by an orifice pathway and the elastic body; a second liquid chamber that a liquid flows to and from the first liquid chamber through the orifice pathway; a first gas chamber with a wall configured by a diaphragm; a second gas chamber capable of communicating with the first gas chamber; and a switching section that switches a state of communication of the first gas chamber and the second gas chamber.

A hydraulic engine mount with two channels is provided, which reduces vibration effectively in ignition mode and rough road mode, improves performance in noise, vibration, harshness (NVH) in a vehicle with stop/start function. The hydraulic engine mount with two channels, provided with a dividing means, comprises a first channel formed along a first path of the dividing means and providing a moving path of fluid between an upper fluid chamber and a lower fluid chamber, a second channel formed along a second path of the dividing means and providing a moving path of fluid between the upper fluid chamber and the lower fluid chamber, and a solenoid device having a first solenoid valve body installed in the housing and configured for opening and closing the second channel.
