A vertical decoupler assembly for a hydraulic mount including a first fluid chamber and a second fluid chamber includes a travel plate defining an interior space for receiving a removable vertical decoupler assembly. The vertical decoupler assembly includes an elastically deformable and tubular shaped diaphragm for dampening small vibrations across the mount. The vertical decoupler assembly may include an inner cage and an outer cage, each including a rigid, perforated, tubular wall disposed on either side of the diaphragm for limiting its radial deflection in each direction. The vertical decoupler assembly may include a rigid lower insert having an inverted cup shape with a second rim sealingly engaging the diaphragm and secured to the inner and outer cages. The decoupler diaphragm also includes a flange and a ring-shaped upper insert for nesting within and sealing against a throat at the upper end of the travel plate.

A mount apparatus () for supporting a vibration source on a base is provided. The mount apparatus () includes a moving member () that is partially disposed in a pumping chamber () for moving within the pumping chamber () along a first axis (A) to create a volume change in the pumping chamber () to maintain the volume of the pumping chamber () to prevent a pressure increase in the pumping chamber () during the deformation of a flexible body () in response to an external excitation to effectively cancel the external excitation. The moving member () includes a moveable wall () of a flexible material, having a generally hour glass-shape in steady state, and extending between moving member upper and lower ends (). The moveable wall () flexes radially outwardly and inwardly relative to the first axis (A) in response to relative axial movement between the moving member upper and lower ends (), to amplify the volume change in the pumping chamber ().

A magnetorheological fluid-based hydraulic mount apparatus () for supporting a vibration source on a base is disclosed. A main fluid passage () extends between pumping chamber () and receiving chamber () for passing the fluid therebetween. Electromagnet coil () variably generates a magnetic flux across the main fluid passage to variably change the damping stiffness of the mount. A rate dip track passage () extends between the pumping chamber () and receiving chamber () for oscillating the magnetorheological fluid () therethrough to decrease the dynamic stiffness of the mount apparatus () at predetermined frequencies. A controller () applies a current through the electromagnet coils () at the predetermined frequencies and frequencies relatively close to and above the redetermined frequencies for substantially preventing the magnetorheological fluid () from flowing through the main fluid passage () to force the magnetorheological fluid () to flow substantially only through the rate dip track passage () for preventing a sharp increase in the dynamic stiffness of the hydraulic mount apparatus () from occurring at these frequencies.

A hydraulic mount apparatus () for supporting a vibration source is disclosed. The mount apparatus () includes a housing () that defines a housing chamber () separated by a partition assembly () into a pumping chamber () and a receiving chamber (), each containing a magnetorheological fluid (). A flexible body () is partially disposed in the pumping chamber () for deforming elastically in response to vibrations caused by an external excitation. A fluid passage () extends between the pumping chamber () and the receiving chamber () for passing the fluid therebetween during low frequency vibrations. A piezostack actuator () partially extends into the pumping chamber () for moving within the pumping chamber () for varying the volume of the pumping chamber () to prevent a pressure increase in the pressure chamber to substantially cancel relatively high frequency vibrations.
