A cylinder with end position damping, comprising a cylinder and a piston unit, wherein the cylinder comprises a cylinder tube, a first closure part and a second closure part, wherein the cylinder tube has a first cylinder tube end and a second cylinder tube end, wherein the first closure part is arranged at the first cylinder tube end and the second closure part is arranged at the second cylinder tube end, wherein the cylinder tube and the closure parts (6, 7) form a cylinder interior, wherein the cylinder comprises a damping zone in at least one end region, wherein the cylinder has at least one opening which is connected to a pressure-medium connection, is assigned to the damping zone and is axially spaced from an axial limitation of the cylinder interior, wherein the piston unit slidably passes through the first closure part and forms at least one working chamber in the cylinder interior, wherein the piston unit comprises a piston body and a piston ring, wherein the piston unit is guided in an axially displaceable manner in the cylinder interior by means of a guide, and the piston body has a circumferential inner ring groove on a radial outer lateral surface, wherein the piston ring is arranged in the inner ring groove, is a resiliently designed and comprises a piston ring gap, wherein the piston unit is designed to pass axially with the piston ring over the opening, which is connected to the pressure medium connection, during a retraction movement into the damping zone and to enclose a damping pressure medium volume in a damping zone chamber in the damping zone, wherein the piston unit is designed to have a first operating state during a retraction movement within the damping zone, a second operating state during an extension movement within the damping zone and a third operating state during a movement outside the damping zone, wherein in the first operating state, an overpressure of the damping pressure medium volume exists relative to the pressure medium connection and the piston ring gap is designed for a throttled outflow of the damping pressure medium volume, wherein in the second operating state, an overpressure of the pressure medium connection exists relative to the damping pressure medium volume and the piston ring gap is designed for an inflow of a pressure medium into the damping zone chamber, wherein the piston ring is configured to assume a working position in the first and second operating states and to rest resiliently against the inner cylinder wall in the damping zone, and wherein the piston ring is configured to assume a pre-tension position in the third operating state, characterized in that the piston unit has a piston ring limiting member which is designed to limit a spring deflection of the piston ring in a relaxation direction and to fix the piston ring in the pre-tension position. comprising a cylinder and a piston unit, wherein the cylinder comprises a cylinder tube, a first closure part and a
