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. | 02-03-2011 |

The housing-foam-cap subassembly is next assembled onto a friction rod with a spring coaxially surrounding the friction rod, having one end abutting the housing and the other end abutting a base at the lower end of the friction rod. | 01-28-2016 |
20160025174 | VARIABLE LOAD CONTROL SYSTEM IN A HYDRAULIC DEVICE - The hydraulic device comprises a tubular housing, inside of which a rod is jointly attached to a piston separating an upper and lower areas filled with hydraulic fluid so that, as the piston and rod move, the two components move together relatively and axially inside the tubular housing, displacing the hydraulic fluid inside the tubular housing, flowing from one area to the other, and thus changing the volumes inside said areas. It also comprises a modular mechanism located inside the lower area that regulates the shock absorption at the maximum level of compression of the hydraulic device, as well as in other relative positions. | 01-28-2016 |
