Since the plunger 80 is coupled on the one hand in an articulated manner with the opening aid actuator 78 and on the other hand in an articulated manner with the opening element 76, the opening element 76 is connected in an articulated manner to the opening aid reactor 78 via the plunger 80.

Since the opening aid actuator 78 on the one hand at least indirectly, in particular directly, is supported or supported on the door 16 and on the other hand supportable or supported on the housing via the opening element 76, then when the opening member 76 along the repelling direction and thereby in the second direction 92nd is moved, the door 16 is ejected via the opening aid 74 of the housing 12 and thereby initially opened.

- the torque is not supported because the opening member 76 and the housing 34, and thus the stator from which, for example, the torque is applied to the rotor, are rotatable relative to the door 16 and the opening member 76 is not yet in the initial state Support system with the housing 12, in particular with the surface 96, is located.
- the housing 34 and thus the stator and the opening element 76 rotate about the axis of rotation 46 relative to the door 16 and relative to the housing 12 in a first direction of rotation illustrated in FIG. 14 by an arrow 108, in particular initially so long the opening element 76 comes in support system with the housing 12.

On the other hand, the torque is then supported via the housing 34 and the opening element 76 on the stop 110 and thus at least indirectly on the door 16. If the drive motor 32 further provides the torque, the torque, by preventing further rotation of the stator via the housing 34 and the opening element 76 by means of the stop 110, results in rotation of the threaded spindle 42 about the axis of rotation 46 relative to the door 16.

- the drive motor 32 provides a torque which acts about the rotation axis 46 in a direction opposite to the first direction of rotation second direction of rotation, which is illustrated for example in Fig. 14 by an arrow 112.
- the opening element 76 formed as a cam 104 is in support engagement with the stop 110, then at least one spring element not recognizable in the figures is tensioned, which thus provides a spring force which acts at least indirectly on the opening element 76.
- the opening element 76 is held against the spring force by means of the drive motor 32 or by means of the torque provided by the drive motor 32 in support system with the stop 110, for example. If the provision of the torque is terminated, the spring element can relax, for example, whereby, for example, the opening element 76 and with it the housing 34 and the stator are rotated in the second direction of rotation relative to the door 16.
- the opening element 76 is rotated or held by means of the spring force in support system with a second stop 114 opposite the stop 110 and provided on the door 16.
- the drive motor 32 provides the torque, also referred to as the second torque, acting in the second direction of rotation.
- the second torque for example, the opening element 76 and thus the housing 34 or the stator, in particular when the opening element 76 is not yet in support with the second stop 114, rotated in support system with the second stop 114 relative to the door 16.
- the opening element 76 is in support contact with the second stop 114, then the second torque is supported on the door 16 via the opening element 76, as described above with regard to the torque for opening the door 16, so that the second torque causes a rotation of the threaded spindle 42 causes about the rotation axis 46 in the second direction of rotation. As a result, the door 16 is pivoted relative to the housing 12 and thereby closed. Since the opening element 76 is in support system with the stop 1 4, the opening element 76 assumes a starting position as in the initial state shown in Fig. 14, so that the opening member 76 does not affect the movement of the door 16 in the closed position S or prevented.
