Embodiment Construction

[0037] Figure 1 to Figure 7 Exemplary different embodiments of a drive device for a wing leaf of a door, window or the like according to the present invention are shown. Here, the driving device 10 includes a housing 12 and a piston-cylinder unit 14 (in particular, see Figure 1 to Figure 3 ), the piston 18 of the piston-cylinder unit that 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 while forming a pressure chamber and a non-pressure chamber, The hydraulic medium 22 is transferable between the pressure chamber and the non-pressure chamber during the corresponding closing and opening movements of the piston 18.

[0038] In addition, in the corresponding drive device 10, the housing 12 is provided with inflow and / or outflow holes 24 for the hydraulic medium 22 to be transferred. The inflow and / or outflow holes are in the corresponding piston 18 of the piston-cylinder unit 14. During the...

Abstract

The invention relates to a drive device for a leaf of a door or window. The drive device comprises a housing and a piston-cylinder unit, the piston-cylinder unit is movably mounted in a cylinder of the piston-cylinder unit by means of a piston forming a pressure chamber and a non-pressure chamber, and the hydraulic medium is displaceable between the pressure chamber and the non-pressure chamber during the respective closing and opening movement of the piston. The housing is provided with an inflow and / or outflow opening for the hydraulic medium to be transferred, which inflow and / or outflow opening is passed one after the other and is closed or released during a respective closing or opening movement of the piston of the piston-cylinder unit. Furthermore, a control valve is provided, the control valve is provided with at least one opening for overflowing hydraulic medium, and the control valve cooperates with an inflow and / or outflow hole arranged in the housing, so that different inflow and / or outflow holes of the housing can be released according to the corresponding adjustment of the control valve in order to overflow the hydraulic medium through the opening of the control valve.

Description

Technical field [0001] The present invention relates to a drive device for a wing leaf of a door, window or the like. The drive device has a housing and a piston-cylinder unit. The piston-cylinder unit is loaded by a spring unit and is connected to a driven shaft. The cooperating piston is movably supported in the cylinder of the piston-cylinder unit while forming a pressure chamber and a non-pressure chamber. During the corresponding closing and opening movement of the piston, the hydraulic medium is in the pressure chamber. It can be transferred to the non-pressure chamber. Background technique [0002] Hydraulic drive devices for doors or windows are well known and cause autonomous closing of the door leaf or window sash, wherein, in the case of the drive device or door closer for the door leaf, not only the movement of the door panel into the door frame but also the door lock is ensured The latch falls into the locking plate. In addition, a mechanical accumulator, such as a...
