Beschreibung
Zusammenfassung:	The sealing system is for fluid of gas conduit cut-off ball cocks. A supply pressure is applied on the seal (12), an associated adjustable control (1-7) being provided. With hydraulic feed the pressure is supplied via a supply line (19) with the chamber (20) of the sealing body (23) bearer body (24). In the line between the chamber and supply source is a multi-path valve (5). This valve on the one hand connects the chamber to the pressure supply source, and on the other hand to a collecting chamber (8) which serves to relieve pressure in the sealing body chamber (20).
