IMPERIAL PATENT OFFICE. In steam engines with rotating pistons, the seal was between the Drive body and the vessel walls associated with great difficulties in the long run, because the wear and tear with the naturally high specific surface pressure was very considerable. BEZW by inserting rollers between the body of revolution. its slider and The walls of the vessels were, however, considerably remedied because of the problem No irregular surfaces could be formed, but permanent wear and tear Sealing has not yet been achieved by inserting only one roller each at the corresponding friction points. The subject matter of the present invention is the construction of the drive body so hit that two rollers immediately behind each other between the former and the vessel walls are rotatably arranged, which ensures permanent sealing , is. The new feature is shown in the accompanying drawing, which shows: Fig. Ι a cross section through the body of revolution and the drive body in a horizontal position, 2 shows the same cross section with the friction body in a vertical position, 3 shows a plan view of the drive body, FIG. 4 shows a view of the drive body in a position pushed laterally out of one another, and FIG. 5 shows a section through the latter along line AB of FIG. In the body of revolution α of a circulation steam engine, the drive body b and c, which consists of the two sliding pieces b and c, which are also displaceable relative to one another, is mounted, displaceable in its longitudinal direction. For the purpose, the ends of the sliding pieces, which in a known manner by means of rollers / g · respectively. hi come into contact with the walls of the housing, with uniform pressure to act on the surfaces of the housing walls, the two sliding pieces cross in the middle by penetrating each other in -side cutouts. So there form g and / and also h and i, the ends of each slider b respectively. c, and this storage of the sliding pieces allows them to adapt to the shape of the walls everywhere without changing their own length.
