The invention proceeds from a rotary piston machine (2) which operates as pump, compressor or motor, having a first rotor (4) and a second rotor (6), wherein the first rotor (4) is arranged so as to lie opposite the second rotor (6). The first rotor (4) has a first end surface (8) with a first toothing system (10). The second rotor (6) has a second end surface (14) with a second toothing system (16). The first (10) and the second toothing system (16) are formed in each case from at least one tooth (12, 18). The toothing systems (10, 16) are in engagement with one another in such a way that working spaces (20) by meshing of the teeth (12) of the first toothing system (10) and the teeth (18) of the second toothing system (16), wherein volumes which are formed by the working spaces (20) are changed by the meshing of the teeth (12, 18). The rotors (4, 6) are received by a housing (22) with an inner wall (24), wherein the inner wall (24) largely replicates an outer contour (26) of the rotors (4, 6). The first rotor (4) has a first rotational axis (I). The second rotor (6) has a second rotational axis (II). The first rotational axis (I) and the second rotational axis (II) enclose an angle (f) which does not equal 0°. According to the invention, a first pin element (28) which is connected fixedly to the housing (22) in the translatory direction protrudes into the first rotor (4). A second pin element (32) which is connected fixedly to the housing (22) in the translatory direction protrudes into the second rotor (6). The first pin element (28) and the first rotor (4) and the second pin element (32) and the second rotor (6) interact in such a way that the rotors (4, 6) are guided rotatably in the housing (22). |
