Abstract
A fitting, in particular for shutting off a flow, includes a housing. A fixed threaded part is axially displaceable and fixed against relative rotation in the housing. A rotatable threaded part is axially resiliently and rotatably supported in the housing. A braking device has at least two friction surfaces facing toward one another and being pressed against one another with a braking force if a predetermined rated force upon the fixed threaded part is exceeded, in order to brake a rotary motion of the rotatable threaded part through an axial displacement and form a braking surface. One of the friction surfaces is connected to and fixed against rotation relative to the rotatable threaded part. A cup spring assembly has a width, an intermediate radius and at least one cup spring for resiliently supporting the rotatable threaded part in at least one axial direction. The braking force relative to the width of the cup spring assembly is introduced over the intermediate radius of the cup spring assembly.
