Abstract:
1. A hydraulic mount comprising: a resilient hollow body defining a primary and a secondary fluid chamber separated from one another by a partition having a first orifice track therein providing fluid communication between the primary and secondary fluid chambers, the first orifice track having a wall thereof defining a first opening into the primary fluid chamber and a second opening into the secondary fluid chamber; a first and a second attachment device disposed along a mount axis extending through the resilient hollow body for receiving a load; the first orifice track defining a first track axis extending between the first and second openings and including a transverse section thereof wherein the first track axis extends transverse to the mount axis; and a secondary orifice track-mass body disposed within the transverse section of the first orifice track and sealed to the wall of the first orifice track by a resilient tethering member for limited reciprocating movement within the transverse section of the first orifice track, the secondary orifice track-mass body defining a second orifice track therein providing fluid communication through the secondary orifice track-mass body for passage of fluid received from the first fluid orifice track; wherein the first orifice track defines a generally rectangular shaped cross section thereof in the transverse section of the first orifice track, the rectangular shaped cross-section having an upper and a lower wall connected by a pair of spaced side walls; and the secondary orifice track-mass includes upper and lower surfaces respectively thereof in sliding contact with the upper and lower surfaces of the first orifice track, and a pair of spaced side surfaces thereof connected to the side walls of the first orifice track by imperforate resilient tethers.
