Abstract: A door closer comprising a drive spindle which is operably connected to a first spring configured to apply a first closing torque to the drive spindle, wherein the drive spindle is also operably connected to a second spring configured to apply a second closing torque to the drive spindle, wherein the connection between the first spring and the drive spindle is independent from the connection between the second spring and the drive spindle, and wherein variation of the first closing torque as a function of drive spindle orientation is different from variation of the second closing torque as a function of drive spindle orientation.
