Abstract: Provided is a spring sleeve for a piston cylinder unit, wherein the spring sleeve is adapted to receive a spring, at least partially, and to guide it, wherein the spring sleeve has a cylindrical sleeve inner surface. The embodiment further relates to a cylinder for a piston cylinder unit, wherein the cylinder) is adapted to be arranged inside a spring of a piston cylinder unit. The embodiment also relates to a piston cylinder unit, including a cylinder, a spring arranged concentrically around the cylinder, and an inner spring sleeve and outer spring sleeve each arranged concentrically around the spring, wherein the cylinder and the spring are arranged inside the inner spring sleeve and the outer spring sleeve. Finally, the embodiment relates to a method of manufacturing such a piston cylinder unit.

Abstract: A fluid damper is provided including a cylinder filled with a damping fluid, a piston base body shiftably guided in the cylinder along a stroke axis, and a valve disk spaced apart from a shell wall of the cylinder. The piston base body divides an inner space of the cylinder into a front space and a rear space along the stroke axis. In the piston base body, there is at least one channel connecting the front space to the rear space in a fluid-conducting manner. The valve disk is shiftably guided along the stroke axis between an opening position unblocking the at least one channel and a closing position closing the at least one channel. The valve disk has a central area extending radially outward from the stroke axis, the central area being free of apertures.
