Summary:PCT No. PCT/DE90/00136 Sec. 371 Date Sep. 25, 1991 Sec. 102(e) Date Sep. 25, 1991 PCT Filed Feb. 27, 1990 PCT Pub. No. WO90/11919 PCT Pub. Date Oct. 18, 1990.A cylinder-piston unit including a central valve having a valve shaft, on which two spring plates with a pre-stressed restoring spring are disposed. One of the spring plates is engaged from behind by a cross-sectional enlargement of the valve shaft which has a valve closing element. The cross-sectional enlargement is formed by a collar of the valve shaft. Another cross-sectional enlargement comprises a sleeve, which is longitudinally displaceably guided on the valve shaft. On the side remote from the restoring spring, the sleeve has an enlarged inner bore, with which the enlarged inner bore complementarily fits over a snap ring that engages the valve shaft. As a result, a form-locking connection is attained between the sleeve and the valve shaft that assumes that a preassembled valve component unit will be held together even if the snap ring breaks.
