ABSTRACT:
A hydrokinetic torque converter has a main impeller driven by an internal combustion engine, an auxiliary impeller that can be engaged into drive connection with the main impeller by an impeller clutch, a turbine coupled to an output shaft, and a stator which together form a converter circuit filled with hydraulic fluid. The impeller clutch has a clutch member that engages with the auxiliary impeller in a rigid, non-rotatable fashion. The clutch member forms the separating wall between two chambers, each of which is connected by at least one fluid flow passage to an associated hydraulic line, which leads to a supply system and acts depending on its operating state, as an inflow or outflow line creating a pressure gradient between the chambers. Based on the pressure gradient the clutch member can be set in either a first position, in which it is connected in rotary fashion to the converter housing, or in a second position, in which this rotary connection is released.
