A torque converter includes a turbine disposed in a hydrodynamic chamber. A bypass clutch has an apply chamber fluidly isolated from the hydrodynamic chamber. A first hydraulic passage is in fluid communication with the apply chamber. A variable-pitch stator including blades controllable by an actuator that has a chamber in fluid communication with the first hydraulic passage.

A torque coupling system including an input shaft, a main cam affixed to the input shaft, a clutch housing that surrounds the input shaft and provides an inter space, a scoop plate affixed to the clutch housing, an external housing that encloses the clutch housing and provides an outer space, and a main clutch that is articulable between a disconnected drive mode and a all-wheel drive mode. In the disconnected drive mode the main clutch disengages the input shaft from the clutch housing and the main cam rotates with the input shaft to transfer lubricant from the inner space to the outer space while in the all-wheel drive mode the main clutch engages the input shaft with the clutch housing and the scoop plate rotates with the clutch housing to scoop the lubricant from the outer space to inner space through the catch tank.

A hydrodynamic machine contains a bladed primary wheel driven by a rotary shaft and a bladed secondary wheel, which together form a work chamber filled with a working medium. The machine has a pressure pump for delivering a working medium from the work chamber. The pressure pump has a first inlet, which projects into the work chamber, and has a first inlet opening which is aligned with the rotary shaft in the circumferential direction. The pressure pump has a second inlet which projects into the work chamber and has a second inlet opening which is aligned to the rotary shaft in the circumferential direction opposite to the first inlet opening. The first and second inlets are joined to a common working medium channel behind the two inlet openings. The first and second inlets extend adjacent to each other in the same flow direction separated by a separation wall.
