Abstract: A hydraulic drive for a sash of a door, a gate, a window or the like comprises a housing and a piston which is displaceably guided in the housing and which divides the interior of the housing into a pressure chamber and a non-pressurized chamber. In this case, the drive, which can in particular be a hydraulic door closer, comprises a regulating valve which is arranged on the end face of the housing delimiting the pressure chamber on the side facing away from the piston and which is integrated in particular in a housing cover for activating an impact function. The regulating valve has a valve member which is displaceable between a closed position and an open position in a valve bore of a valve housing formed in particular by the housing cover, is impinged on in the closing direction by the pressure in the pressure chamber and can be transferred into the open position thereof by the spring force of a spring unit when the pressure in the pressure chamber falls below a predeterminable limit pressure.

Abstract: A mechanism for influencing opening and closing movements of a wing of a door, a window, or the like. The mechanism includes a sliding arm disposed between the wing and a fixed frame. The sliding arm is rotatably mounted to the wing or on the frame. A sliding block is disposed in a sliding rail and is coupled to the sliding arm. The sliding rail or the sliding block has means for energy conversion through which mechanical kinetic energy generated by the sliding block is converted into electrical energy to supply at least one electrical component with electric current to at least one of generate a braking torque or drive the sliding block.

Abstract: The drive according to the invention for a wing of a door, a window or the like comprises a housing, a drive shaft supported rotatably in the housing, and a piston that interacts with the drive shaft and is guided slidably in the housing. In addition, the drive comprises energy conversion means interacting with the piston, by which energy from the movement of the piston can be converted to electrical energy, and electrical energy produced in this way can be converted back to mechanical energy, to supply at least one electrical component with electric current, to generate a braking torque and/or to drive the piston, especially to support the closing and/or opening movement.

Abstract: A mechanism for influencing the opening and/or closing movement of a wing of a door, a window or the like comprises a sliding arm disposed between the wing and a fixed frame, being mounted rotatably on one hand on the wing or frame and on the other hand, guided by a sliding block in a sliding rail disposed on the frame or wing. Here, energy conversion means are assigned to the sliding rail and/or the sliding block, through which the kinetic energy of the sliding block can be converted to electrical energy, and electrical energy produced in this way can be converted to mechanical energy, in order to supply at least one electrical component with electric current, to generate a braking torque and/or to drive the sliding arm, at least in sections, especially to support the closing and/or opening movement.

Abstract: The invention relates to a retracting device for a leaf of a door or a window, comprising a housing, a piston which is arranged in a receiving area of the housing and which is urged by a spring, and a shaft which is mounted in the housing and which interacts with the piston, an actuating arm for the leaf being arranged on the shaft in a non-rotatable manner. At least one first driving element is arranged on the shaft, the head surface of said driving element forming a freewheel device with a freewheel region, wherein an arrangement of the piston or a tooth of a toothing of the piston slides on the freewheeling region so as to decouple the shaft from the piston.
