    Patent number: 6651988
    Abstract: An actuator for use in an active mount system for reducing vibration transmission from a vibrating component to a support structure. The actuator is disposed in a housing that is attached to the vibrating component or the support structure. The actuator includes a piston moveably disposed in a casing, and a piston rod assembly that is connected to the other one of the vibrating component or the support structure. A seal assembly, disposed either in a groove in the piston or in a groove in the casing, provides a seal between the piston and casing.
