ABSTRACT:
The hydraulic mount assembly includes a hollow body connected to a pair of mounting members. A resilient diaphragm closes the hollow body thereby forming a closed cavity that is filled with damping liquid. A partition divides the cavity into primary chamber and secondary chambers. An orifice track and a decoupler passage are provided in the partition to communicate with both the primary and secondary chambers. A tiered decoupler is positioned for limited reciprocal movement in the decoupler passage. The tiered decoupler includes a plate, that is received and held for limited reciprocal movement within an annular groove in the partition. A pair of plungers that are interconnected by slide rods extending through apertures in the plate and reciprocate in tandem with respect to the plate. This relative reciprocal movement between the plate and plungers generates laminar flow around the decoupler during transition in response to high frequency vibrations for a reduced dynamic rate and smoother/quieter operation.
