Abstract
A device for absorbing vibration is disclosed, along with compensator elements for use therein. The device comprises a primary fluid system for dynamic isolation and/or damping, and a volume compensator having an auxiliary chamber fluidly interconnected with, but dynamically isolated from, the primary fluid system. The volume compensator features a compensator element having an elastic layer in fluid communication with the auxiliary chamber and disposed in sealing engagement within the device. The compensator element advantageously comprises a deformable elastomer stiffener cooperative with the elastic layer for providing static pressurization to the primary fluid system. The compensator element may further provide a reduced rate of change in volume stiffness characteristic that allows the fluid pressure in the primary fluid system to increase at a reduced rate. Further, the reduced rate characteristic prevents excessive static pressure swings. The compensator element may further comprise a seal bead. Additionally, the device features an adhesive bond fluidly sealing at least one end of the primary fluid system.
