Document Type and Number:
Japanese Patent JP2010529374
Kind Code:
A
Abstract:
The invention relates to a torque transmission device, especially for the drive train of a motor vehicle, said device comprising a pump comprising a first pump part, a second pump part, a suction chamber and a pressure chamber, the first pump part and the second pump part being mutually rotatable. A rotary movement of the first pump part in relation to the second pump part allows a hydraulic fluid to be transported from the suction chamber into the pressure chamber of the pump, torque transmitted between the first pump part and the second pump part depending on the pump pressure generated by the pump. At least one pressure control device is associated with the pump, said device constricting a fluid stream transported by the pump in a variable manner in order to vary the rotational speeds of the first pump part and the second pump part in relation to each other.
