A method and device are provided for sealing a first oil environment, which is located on a first side of a movable piston guided in a hollow chamber, from a second oil environment, which is located on a second side of the piston. The piston can move back and forth in the hollow chamber between the two oil environments in the axial direction by a piston stroke length (d). Two annular seal elements are disposed around the movable piston so as to sealingly contact the inner circumferential wall of the hollow chamber. The annular seal elements are spaced from each other by at least a distance (D) in the axial direction that is greater than or equal to the piston stroke length (d).
