Abstract

A freewheel unit intended especially for the stator of a hydrodynamic torque converter, allows first and second elements to rotate relative to each other around a rotational axis essentially in only one direction. A locking element carrier extends in the circumferential direction around the rotational axis and comes at least one first locking element which extends away from this carrier toward the first element in a first circumferential direction. At least one first locking element can come to rest against at least one blocking surface provided on the first element to prevent any relative rotation between the first element and the locking element carrier in one direction of relative rotation.
