Abstract
A piston for a piston cylinder unit, particularly a gas spring, is to be provided with a piston ring and comprises a portion extending at least from the piston ring groove to a free end and consisting of a plurality of segments separated from one another by longitudinal slots. This portion is provided with a bore the diameter of which is at the free end smaller than the diameter of the related portion of the piston rod. It is the purpose of these measures to enable simple assembly of the piston ring in the piston ring groove and at the same time to ensure reliable seating of the piston ring.
