Tue, 07 Apr 2015 08:00:00 EDTA two vacuum actuated switch mechanism is provided within an engine or hydromount. First and second ports are provided along a peripheral portion of an inertia track assembly. A decoupler or vacuum diaphragm is selectively exposed to vacuum through a first port. Under the influence of the vacuum, the decoupler can no longer oscillate. If vacuum is applied only to the decoupler, and not and idle diaphragm, the fluid is forced through a low frequency inertia track which creates high levels of damping and low frequencies. If vacuum is also applied to the decoupler and the idle diaphragm, the high frequency inertia track is opened and causes the fluid to flow therethrough. This creates a high frequency dynamic rate dip. Alternatively, if no vacuum is applied to either the decoupler or the idle diaphragm, the decoupler is allowed to freely oscillate creating a decoupled state for low input displacements. Higher input displacements results in fluids being forced through the low frequency inertia track. An integrated accumulator is disposed between the port and the decoupler to reduce or eliminate air resonance response, buffering the pumping effect of the decoupler in a decoupled state.
