Abstract
The equipment has at least one fluid-activated piston (3). In its end positions the piston works together with a valve. Radial barrier elements (13) are arranged coaxial to the piston, and are spring-loaded so as to work together in the axial direction with a bearing shoulder on the piston, when in the securing position. The barrier elements may be guided in radial breaks in a sleeve (17), which can be moved coaxially against the force of a spring (10).
