Patent Number: 6,308,933

Title: Shut-off-valve-utility

Abstract: A shut-off valve has a housing which is provided with a spindle bush. Located in the spindle bush is a movable spindle which is sealed with respect to the housing. The spindle is connected to a closure body disposed in the housing. The housing also has a recess, which extends around the spindle bush and is open to the interior of the housing. If the housing comes under internal pressure, the recess prevents corresponding deformation of the spindle bush. The latter can thus not become leaky under the action of the internal pressure.
