The invention relates to a fluid-energy machine (1), with an external rotor (2) which is rotatably mounted about an external rotor rotational axis (3), and with an internal rotor (5) which is rotatably mounted about an internal rotor rotational axis (6) which is different from the external rotor rotational axis (3), which internal rotor (5) is arranged in a rotor receptacle of the external rotor (2) and whose outer circumferential surface (15) bears sealingly against an inner circumferential surface (14) of the external rotor (2) at a sealing point (17), which inner circumferential surface (14) delimits the rotor receptacle, wherein there is a fluid space (16) between the outer circumferential surface (15) of the internal rotor (5) and the inner circumferential surface (14) of the external rotor (2), which fluid space (16) is divided into a first fluid chamber (19) and a second fluid chamber (20) by a connecting lever (18) which is rotatably mounted firstly on the internal rotor (5) about a first connecting lever rotational axis (28) and secondly on the external rotor (2) about a second connecting lever rotational axis (29). The invention furthermore relates to a drive device and a method for operating a fluid-energy machine (1).
