Claim 1:
2. The piston according to claim 1, wherein the piston end face has a depression in which a rubber-elastic sealing element is arranged, wherein the first sealing portion is part of the sealing element, wherein the piston body and the sealing element have mutually complementary geometries so that they form the first vent channel with a first free cross-sectional area, and in a pressure-relieved state, between mutually opposing surfaces of the depression and the first sealing portion, form a second vent channel with a second free cross-sectional area, wherein the first vent channel and the second vent channel are hydraulically connected in parallel, and furthermore wherein the depression and the sealing element are configured such that, as the temperature of the sealing element rises, its modulus of elasticity falls, and a pressurisation of the sealing element by the working fluid leads to a temperature- and pressure-dependent elastic deformation of the sealing element, and by means of the elastic deformation, to a reduction in the free cross-sectional area of the second vent channel.
