Abstract: A swing leaf operator having a closer portion is described. The closer portion has an output shaft, on which a cam disc is torsion-resistantly disposed, as well as a pressure roller. By way of an operational connection, a closer spring presses the pressure roller against a running surface of the cam disc. The pressure roller, with regard to an axial center of the output shaft, is disposed such that, during an opening or closing of a swing leaf coupled to the output shaft, the pressure roller is moved along a path. Due to the fact that the path bypasses the axial center of the output shaft and on account of the configuration of the running surface of the cam disc, in different modes of operation of the swing leaf operator at a respective opening angle of the swing leaf, a very similar or identical torque is respectively applied to the output shaft. Furthermore, the swing leaf operator has a drive motor, which is in operational connection with the output shaft.

A linear drive, according to the invention, for at least one part which is movable along a movement path, particularly a sliding door leaf, has at least one linear motor for the at least one part. A stator part of the linear motor is received in a receiving profile so as to be prevented from falling out. The receiving profile is constructed to be arranged at a fastening device, which is arranged in turn on the installation side of a wall portion or top portion. Accordingly, the stator part and receiving profile form a module or unit, which can be mounted in its entirety. Therefore, a person performing the mounting can use the receiving profile for mounting, which helps to reduce the risk of damaging the stator part, for example.
