Definitions
- the invention relates to a hydraulic swing door drive for swing doors with an actuating piston, which acts on a drive shaft, and with a hydraulic pump connected to the actuating piston via a hydraulic circuit acts.
- Hydraulic rotary leaf drives are used today by hydraulic units driven, which work with an almost constant power.
- the hydraulic units usually consist of an asynchronous machine, a hydraulic pump (e.g. a gear pump) and a Pressure relief valve.
- a hydraulic pump e.g. a gear pump
- a Pressure relief valve e.g. a pressure relief valve
- the full hydraulic power is only used during a very short phase of the opening cycle, while excess hydraulic power in the other opening phases is discharged via the pressure relief valve, so that in the Usually only about 1/3 of the total hydraulic work generated by the connected Part-turn actuator included and 2/3 via the pressure relief valve destroyed, d. H. is converted into heat.
- a pressure relief valve is for a very compact actuator unsuitable, because a large engine is necessary has a high space requirement. Furthermore, arises due to poor efficiency a large amount of heat loss, which from a compact The device is difficult to remove, especially in the case of concealed installation is.
- the solution according to the invention has the advantage that the training As a closed circuit, only as much hydraulic power is available is placed as is currently required. So it doesn't come to losses in the hydraulic circuit. As a result, for one thing a smaller motor with less space can be used and that on the other hand, there are no large amounts of heat loss that must be dissipated.
- the rotary vane drive according to the invention can thus Use even in the smallest space and in a concealed installation Find.
- the hydraulic pump is in its Variable speed drivable. This allows only one at a time hydraulic power is provided on demand and that less energy is needed overall.
- the hydraulic pump is also in its direction of rotation changeable drivable. This gives the opportunity to Hydraulic drive not only to drive in one direction, but also to run backwards so that the door is actively Hydraulic pump can be closed.
- the drive for the hydraulic pump is preferably one in its speed and / or used in its direction of rotation variable motor. Consequently can adjust the volume flow of the hydraulic drive unit in simply to the volume flow required by the rotary actuator by adjusting the drive speed or the drive direction the hydraulic pump can be controlled.
- Such a motor is preferably a DC motor or an asynchronous motor trained with frequency converter. These engines are due their design is particularly suitable for the intended purpose.
- the suction side of the hydraulic pump connected to a piston space on the rear This will make a closed circuit is formed, which is particularly simple.
- the pressure side of the hydraulic pump is connected to a front piston chamber.
- a piston chamber 1 shows a possible embodiment of the invention hydraulic rotary leaf drive shown.
- a piston chamber 1 is a Adjusting piston 2 is slidably mounted on a rack 3 with a Pinion 4 is in active engagement with a drive shaft 5 one is not swing door shown is connected.
- a control piston 2 is still a Tank room 6 arranged.
- the piston chamber 1 forms one in front of the actuating piston 2 (left in the figure) front piston chamber 7 and behind the actuating piston 2 (right in the figure) a rear piston chamber 8.
- the rear piston chamber 8 is via a line 9 connected to the suction side of a hydraulic pump 10 and the Front piston chamber 7 is via a further line 11 with the pressure side connected to the hydraulic pump 10. This creates a closed one Circulation.
- the hydraulic pump 10 is driven by a motor 12, which both is variable in its speed and in its direction of rotation and the preferably as a DC motor or as an asynchronous motor with frequency converter is trained.
- a motor 12 which both is variable in its speed and in its direction of rotation and the preferably as a DC motor or as an asynchronous motor with frequency converter is trained.
- the Drive speed of the motor 12 is the volume flow of the hydraulic pump 10 adapted to the volume flow required by the swing door operator become.
- by changing the direction of rotation of the Motor 12 run the hydraulic pump 10 backwards and so the to Actively close the swing door connected door.
- a rotary leaf drive can be constructed, which as Swivel drive for a door closer with rack or cam gear serves and a spring is tensioned by opening the door becomes. It is only necessary to take into account that the individual pressure rooms the door closer, namely the front and the rear piston chamber, as well as the tank space through various check and throttle valves are connected so that when driving with a closed Additional switching valves are required. This will, however does not affect the basic principle of a closed hydraulic circuit.
