Abstract (en)
[origin: EP1355030A2] Hydraulic turning sash drive for swing doors comprises an actuating piston (2) acting on a drive shaft (5), and a hydraulic pump (10) acting via a closed hydraulic circuit on the actuating piston. Preferred Features: The hydraulic pump can be driven at different speeds in different directions. The hydraulic pump is driven by a motor (12) which can be driven at different speeds and in different directions. The motor is a d.c. motor or an asynchronous motor. The intake side of the hydraulic pump is connected to a rear piston chamber (8) and the pressure side is connected to a front piston chamber (7). At least one non-return valve (14) is provided in the connection line (13).
