1. In a control organ for a gaseous and liquid media with a housing whose interior space can be connected via two connecting pieces to a media source on one hand and a consuming device on the other hand, wherein two shut-off elements are arranged inside of the housing in the passageway of the medium, one of which is fixedly connected to the housing, while the other one is displaced with respect to the housing, the improvement which comprises:

  • at least two concentric pipes which serve as shut-off elements, at least one of the pipes being fixedly connected to the housing and at least one of the pipes being movable in the longitudinal direction, the pipes being arranged in the housing so that the outer space of the outermost pipe is connected to one of the connecting pieces and the inner space of the innermost pipe is connected to the other one of the connecting pieces and in specified zones of their cylindrical surfaces all pipes exhibit passage slots taking a parallel course with respect to each other, the passage slots in the pipe fixedly connected to the housing being at an angle which differs from 0°

    with respect to the passage slots of an immediately adjacent movable pipe and the arrangement of the slots on the cylindrical pipe surfaces is such that in a closed position, the zones of the cylindrical surfaces provided with slots of each of the pipes fixedly connected to housing are located opposite closed zones of the cylindrical surface of the adjacent movable pipe and on whose displacement the zones of adjacent pipes provided with slots increasingly overlap.
