Abstract
A hydraulic device disposed in a torque strut so as to provide a fully decoupled hydraulic torque strut. A main rubber element vibrates in response to powertrain pitch torque. At high vibration amplitude, high hydraulic damping is provided via a pumping chamber, an inertia track and a bellowed compensation chamber, wherein a decoupler system hydraulically connected to the pumping chamber is passively disabled. At low vibration amplitude, minimal hydraulic damping is provided via the decoupler system which is connected by a decoupler track to the compensation chamber.
