<p>The drive (1) has an output shaft arranged in a drive housing (2). A sliding arm (5) is rotational fixedly connected with the output shaft. The arm is guided into a sliding rail (3) by a slider (4). A tension spring (6) is arranged in the sliding rail. The slider lies at an actuator (7) of the tension spring in a closed position of a wing (9) and tensions the tension spring. An end of the spring is received in a spring holder (8). The actuator comes into contact with a stop during opening the wing. The holder is displaceable and fixable in the sliding rail for adjusting spring tension.</p> |
