Embodiment Construction

[0036] Figure 1 to Figure 7 Exemplary different embodiments of a drive device according to the invention for a leaf of a door, window or the like are shown. Here, the drive device 10 comprises a housing 12 and a piston-cylinder unit 14 (see in particular Figure 1 to Figure 3 ), the piston 18 of the piston-cylinder unit, which is loaded by the spring unit 16 and cooperates with the driven shaft, is movably supported in the cylinder 20 of the piston-cylinder unit 14 under the condition of forming a pressure chamber and a pressure-free chamber, During corresponding closing and opening movements of the piston 18 , hydraulic medium 22 is transferable between the pressure chamber and the pressure-free chamber.

[0037] Furthermore, in the respective drive device 10, the housing 12 is provided with inflow and / or outflow holes 24 for the hydraulic medium 22 to be transferred, which during a corresponding closing or opening movement of the piston 18 of the piston-cylinder unit 14 T...

Abstract

The invention relates to a drive device for a leaf of a door or a window, said drive device comprising a housing and a piston-cylinder unit, the through-piston of which constitutes a pressure chamber and a pressure-free chamber Mounted movably in the cylinder of the piston-cylinder unit, hydraulic medium is transferable between a pressure chamber and an unpressure chamber during corresponding closing and opening movements of the piston. Here, the housing is provided with inflow and / or outflow holes for the hydraulic medium to be transferred, which are passed successively and closed during the corresponding closing or opening movement of the piston of the piston-cylinder unit or open. In addition, a regulating valve is provided, which is provided with at least one opening for overflowing hydraulic medium, which cooperates with inflow and / or outflow openings provided in the housing, so that in order to pass through the regulating valve The opening overflow hydraulic medium can open different inflow and / or outflow openings of the housing according to the corresponding adjustment of the control valve.

Description

technical field [0001] The invention relates to a drive device for a leaf of a door, window or the like, said drive device having a housing and a piston-cylinder unit, the piston-cylinder unit being loaded by a spring unit and connected to a driven shaft The cooperating piston is movably mounted in the cylinder of the piston-cylinder unit forming a pressure chamber and a pressureless chamber, in which hydraulic medium flows during the respective closing and opening movements of the piston Transferable to and from the pressure-free chamber. Background technique [0002] Hydraulic drives for doors or windows are well known and bring about an autonomous closing of the door or window leaf, wherein, in the case of a drive for the door leaf or a door closer, not only the movement of the door panel into the door frame but also the locking of the door is ensured The latch drops into the locking plate. Furthermore, a mechanical energy store, such as in particular a spring unit, is ...
