Abstract

In a hydrodynamic torque converter, an axial abutment is arranged to support friction discs of a lock-up clutch and a clutch actuator working pressure chamber accommodating an axial piston so as to move with a friction disc carrier. Together with a second friction disc carrier, the friction disc carrier torsionally holds the friction discs in alternating sequence and is also located in a centripetal flow between a pump impeller outlet and a torque converter return conduit.
