ABSTRACT:
A shutoff element comprising a substantially tubular-shaped outer housing and an axially symmetrical inner housing connected by means of rib-like carriers or supports with the outer housing. The axially symmetrical inner housing serves for receiving at least one closure body which can be displaced in axial direction by means of an associated double-acting work cylinder. Each work cylinder is arranged within the inner space of an inner body formed by the inner housing and the inserted closure body in the open position of the shut-off element and is attached to the inner housing. In the free space about the work cylinder there open inlet openings for a cooling medium, the outlet openings of which, in the direction of flow of a work medium, are formed by a ring-shaped opening between the inner housing and the free end of the closure body.
