Abstract
A hydraulic mount apparatus includes a housing having an upper 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 attaches to the partition member separating the pumping and the receiving chambers. A moving member of elastomeric material, disposed in the pumping chamber, attaches to the decoupler. The moving member is molded from a first elastomeric material having a first hardness level and a second elastomeric material having a second hardness level with the first hardness level and the second hardness level being different from one another. The second hardness level is less than the first hardness level.
