Abstract
A mount apparatus (20) for supporting a vibration source on a base is provided. The mount apparatus (20) includes a moving member (134) that is partially disposed in a pumping chamber (64) for moving within the pumping chamber (64) along a first axis (A) to create a volume change in the pumping chamber (64) to maintain the volume of the pumping chamber (64) to prevent a pressure increase in the pumping chamber (64) during the deformation of a flexible body (46) in response to an external excitation to effectively cancel the external excitation. The moving member (134) includes a moveable wall (144) of a flexible material, having a generally hour glass-shape in steady state, and extending between moving member upper and lower ends (140, 142). The moveable wall (144) 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 (140, 142), to amplify the volume change in the pumping chamber (64).
