Abstract (en)

[origin: CN107366487A] A drive for a wing of a window, a door or the like comprises a housing and disposed in the housing, cooperating with an output shaft for opening and closing the wing, acted upon by a spring unit in the closing direction of the piston, through which the housing in a spring unit containing Spring chamber and a damping chamber is divided. The housing is filled with a hydraulic fluid such that a pressure equalization gas volume is left in the spring chamber and hydraulic fluid from the spring chamber can only be transferred into the damping chamber through a sleeve connected to the piston, extending into the spring chamber or a piston rod having at least one outflow channel is, whose cavity or respective outflow channel communicates via at least one inlet opening with the spring chamber. In this case, the sleeve or piston rod are arranged in the spring chamber and a respective inlet opening is positioned so that a respective inlet opening of the sleeve or piston rod is completely surrounded by the hydraulic fluid even at the lowest operating temperature of the drive.
