Abstract (en)

The system (10) has a check valve (14) arranged in a lower housing part (15) of a housing (11) in a side arrangement (I) such that the valve is laterally arranged on a level of a rotational axis (16) of a rudder propeller (100). The housing is partially filled with oil for lubricating and/or cooling a propeller gearbox. The oil is removed from the propeller via the check valve. The lower housing part is rotation-symmetrically formed around the rotational axis of the propeller for supporting a propeller shaft. A connection element is in effective connection with the check valve. An independent claim is also included for a rudder propeller of a watercraft.
