Abstract

The door operating drive has a hydraulically-controlled valve (20) incorporated in the hydraulic circuit for providing the open holding function and provided by a 2/2-way valve with a control piston (22) and a non-return valve (23). The effective piston surface of the control piston is greater than the sealing surface of the 2/2-way valve, so that the control pressure in the open holding valve is less than the pressure in the piston space (1) of the door operating drive.
