ABSTRACT:
In a rotary-piston displacement machine, to seal the flat sealing planes between the end faces of the displacement body (5), executing a circular motion, and the side faces (20) of the stationary housing (7) which run parallel thereto, the end faces of the displacement body (5) are provided with a groove (13) in which an elastic sealing strip (14) made of slideable material is inserted. The sealing strip is pressed by a silicone tube (15) against the side wall (20).
