Abstract
A shutoff device comprising a substantially tubular-shaped housing within which there is fixed at its ends an elastic hose body. The hose body extends in the lengthwise direction of the housing and forms a closable throughpassage which flow communicates an inlet opening of the housing with its outlet opening. The inner wall of the housing and the hose body bound a substantially ring-shaped pressure compartment into which opens a conduit connection arranged at the housing. The hose body has a number of folds which extend essentially parallel to one another.
