- the axial forces acting on the counter rotor 4 are absorbed by the clasping of the clasping region 65.

- the rotor 2 and the counter rotor 4 are spaced from each other to a predetermined second gap 69. This is achieved by passing a subset of the compressed fluid onto the face 88 of the counter-rotor 4.
- the force exerted by the fluid during compression on the Rotor 2 and the counter rotor 4 compensated by the fact that the end face 88 of the counter rotor 4 is also acted upon by a force.
- Start-up phase is still no compacted fluid available, the pressure of which could be directed to the face 88.

- it takes several revolutions of the rotor 2 until a predetermined final pressure of the fluid can be achieved.
- the clasp in the clasp area 65 prevents the fluid during the start of the rotary piston engine during the
- Gap also presses away from the rotor 2. Thus, after only a few revolutions of the rotor 2, a stable operating state is reached at which the compressed fluid has received its predetermined final pressure. Thus, the clenching causes the fluid to reach its final pressure in a shorter time than would be the case without clasping.
- the supply and the discharge of the fluid can in this case take place as has been described in Fig. 2.
- the supply and removal of the fluid can also take place in the axial direction along the second axis of rotation II. This should be in the
- Fig. 4 shows the components of Fig. 3 as a 3D exploded view.
- Fig. 5 shows these components in longitudinal section.
- Compressive fluid is supplied to the working spaces 24 via an inlet opening 90 arranged in the second cover 74 parallel to the second axis of rotation II.
- the fluid flows through a second inlet control opening 92 integrated in the third slide bearing 72 and third entry control openings 94 formed in the end face 88, which are connected in a fluid-communicating manner with at least one inlet control channel, not shown here, wherein the inlet control channel communicates with at least one second tooth flank 22 in FIG second toothing 16 formed opening 104 is connected fluidkommunitend.
- This opening 104 may also be formed in the second tooth space 20 of the second toothing 16. The medium to be compressed enters through these openings 104 into the opening work spaces 24.
- Opening 104 which is connected by means of an outlet control channel not visible here with at least one third outlet control openings 96, via a formed in the third sliding bearing 72 second outlet control opening 98 and in the second lid 74 to the inlet opening 90 in parallel
- Outlet opening 102 removed from the rotary piston machine. So that the fluid can be compressed in the rotary piston machine, the supplied fluid within the rotary piston machine essentially has no connection to the discharged fluid.
