摘要： The invention relates to an actuator with an anti-backbend chain, a drive motor, and a worm which can be driven by the drive motor and which comprises a helical groove. The anti-backbend chain has engagement means and is guided along the worm, and the chain is in engagement with the worm by means of the engagement means and the helical groove to drive the anti-backbend chain. Such an actuator should have a more compact design and should optionally exhibit less wear. For this purpose, the core diameter of the worm is larger than twice the distance from the motor axis to the motor exterior along which the anti-backbend chain is guided, and the anti-backbend chain is guided at least partly along the drive motor by means of the engagement means.

摘要： A push pull chain is provided with chain links that are connected to each other by respectively one chain joint, designed in a space-efficient manner. The chain joints of a first chain section with their joint axes have a first orientation, whereby the joint axes of the chain joints of a second chain section are arranged in a second orientation that is twisted around the longitudinal axis of the push pull chain or whereby they can be set to this orientation. In addition, a pertaining chain drive is provided.
