Oil pump, location The oil pump (crescent-type pump) (6) is installed in the torque converter housing behind the torque converter and is driven by the drive flange of the torque converter.

Oil pump, task To produce the oil pressure required for the hydraulic sequences

Oil pump, design An external gear (6a) which is mounted eccentrically in the pump housing in located on the internal gear (6b) which is connected to the drive flange (6b). The crescent (6c) drives the external gear (6a).

Oil pump, function When the engine is running oil is delivered through the suction gallery (6e) along the top and bottom side of the crescent (6c) to the pressure chamber (6d) of the housing. The meshing of the teeth prevents oil from flowing from the pressure side to the suction side.
