1. A suction oil filter for a transmission or an internal combustion engine, comprising:
an oil filter housing (2) made of plastic having at least one suction channel (10) connectable to a suction side of a suction pump and at least one return channel (12) opening into the suction channel (10) for a return pressurized oil flow returned by the suction pump,
wherein the return channel (12) comprises at least one nozzle (13), and at least one pressurized oil supply pipe (14) connected to the return channel (12) and connectable to a pressure side of the suction pump, wherein the nozzle (13) is in a region of an opening into the suction channel (10) outside the at least one pressurized oil supply pipe (14),
wherein aside from the return channel (12) the pressurized oil supply pipe (14) is positively connected to an outer surface of the oil filter housing (2) by way of at least one contour connection.
