   Muttm'1 /. There are a number of adjusting screws p which lie against a short, smooth pair of glasses q to press a packing ring r against the inner, cylindrical surface of the stuffing box and thereby prevent the steam from leaking from the steam space g1 to the atmosphere.



  By screwing in the nut it, the gland h is adjusted in the longitudinal direction, while tightening the screw pins p effectively prevents the steam from leaking from the steam space.



   According to the embodiment shown in FIGS. 4 and 5, a conical seal is used in conjunction with a piston seal. The longitudinal adjustment of the packing sleeve is effected according to this embodiment by screw nuts which can be moved simultaneously by a toothed ring, as is known for packing sleeves in piston rods. The socket A is provided with eyes u through which screw pins v with nuts w pass. The nuts 10 have teeth in which the ring gear of a ring x engages, which can be determined by a fuse y. In this case, no special precautions need to be taken to prevent the steam from leaking from the space 9.
