The impeller (3) is an integral part of the converter housing. The impeller consists of curved blades placed radially along the inside of the housing on the transmission side of the converter. As the converter housing is rotated by the engine (4 and 5), so is the impeller, because they are one and the same and are the driving member of the system.
