摘要： A shutoff valve incorporating a plunger piston which carries at least one axially compressible sealing ring for sealing the piston against the valve housing, and which in each actuated position is subjected to an axial elastic compression which increases in the closed position of the valve plunger piston during further movement of an actuation spindle carrying the piston in the valve closed direction. The sealing ring is clamped between a first piston part or portion and an annular spring which cooperates with a second piston part or portion. In the closed position of the plunger piston, this annular spring bears against a stop fixed to the valve housing, so that the annular spring is displaced relative to both piston parts which are fixedly connected with one another during further movement of the actuation spindle in the closed direction of the valve in the sense of exerting an additional axial compression upon the sealing ring.
