A door actuator for opening and/or closing a door leaf includes a housing, an output shaft rotatably supported in the housing and with a cam disc, wherein the output shaft is formed for transferring torque onto the door leaf. A first element of motion is linearly movably guided in the housing with a first contact surface. A second element of motion is linearly movably guided in the housing with a second contact surface. A distancing arrangement is disposed in the housing. The cam disc is disposed between the two contact surfaces and for rolling on the two contact surfaces. In at least one delimiting range of angles of rotation of the output shaft, the distancing arrangement delimits the minimum distance between the elements of motion, and, in at least one free range of angles of rotation, does not delimit the linear mobility of the two elements of motion in relation to each other.

Some embodiments are directed to a vehicle door assembly that includes a vehicle door, which defines an interior and is connected to the motor by the linkage, such that actuation of the actuator engages the motor, which thereby moves the vehicle door via the linkage. The vehicle door assembly also includes a powered door override. At least a portion of the powered door override can be disposed within the interior of the vehicle door. The powered door override is configured to disconnect the linkage from the motor so as to isolate the motor from the vehicle door and thereby enable the vehicle door to be moved manually. An interior panel is connected to the vehicle door so as to cover at least a portion of the interior of the vehicle door, such that the powered door override is at least partially enclosed between the interior panel and the vehicle door.
