Abstract
A hydraulic mount apparatus includes a housing having an upper portion and a lower portion disposed on a center axis and defining a housing chamber. A partition member is disposed in the housing chamber dividing the housing chamber into a pumping chamber and a receiving chamber. The pumping chamber extends between the upper portion and the partition member. The receiving chamber extends between the lower portion and the partition member. A decoupler is attached to the partition member separating the pumping chamber and the receiving chamber. A moving member is disposed in the pumping chamber and attached to the decoupler. The moving member is made from a non-elastomeric polymer sheet secured to the decoupler for providing the additional damping force.
