<p>In a rotary piston machine with a tight chamber (11) comprising a lateral groove (13) in which rigid blades (5) rotate and which are engaged into a slot of a disk-shaped rotor (7) rotating therewith and which makes tight the inclined edges of the groove (13), excessively high bearing forces are often generated by the large surface disk rotor (7). Said forces are eliminated by the present machine. The following measures enable to obtain that the upper face (22) of the rotor parts (7a) bearing on the sealing inclined surface (6) is not loaded by the pressure prevailing in the cover (2) on the disk-rotor (7), in other words it is made tight with respect to the volume in the cover, coming from the pressure side; 1) the axially opened rotor (7) is hydrostatically unloaded since it rotates between two planes, 2) since on the rotor a pressure build-up is prevented by making the upper parts tight, 3) since the lower parts of the sector-shaped rotor (7a) varying on the sealing surface (6) are bound only in a loose or elastic way with the rest of the rotor (7) which receives the forces, e.g. which is pivoted. By eliminating any useless friction while providing a good sealing, said positive displacement machine has better performances than any other rotary system.</p> |
