Abstract
Rotary piston machine for compressible media, with rotary pistons sealed tight in a common housing and rotatable with one another in a controlled manner, the rotary pistons having a plurality of disk-shaped sections engaging in one another in pairs, whose thickness and/or diameter decreases in the direction of the pressure side, each disk having a surface area and a core area connected respectively by an interface area, the sector angles of the surface area and of the core area of a respective disk not being identical, the disks having various transverse profile contours periodically recurring along the piston axes and each disk being offset at an angle to the two adjacent disks of the same rotor in a such a way that these three disks have a common area section and form a chamber.
