Abstract (en)
[origin: WO2006066664A1] The invention relates to a door drive mechanism (1), especially a revolving door drive mechanism. Said drive mechanism comprises a drive unit (2), coupled to the door via an output shaft (9) and arranged in a housing (13), a motor (3), functionally linked with the drive unit (2), and a spring energy storage device (4) housed in the housing (13) and coupled to the motor (3) and the drive unit (2). A hydraulic pump (5) is functionally linked with the motor (3) and hydraulically linked with a hydraulic compartment (6) representing a tank volume and with a separate pressure compartment (7) associated with the spring energy storage device (4).
