1. A fluid machine, comprising a rotor (2), which rotor (2) is rotatably arranged about a rotational axis (A) in a rotor space (3) of a housing (4) of the fluid machine, wherein, for exchanging energy between a flow energy and a mechanical rotational energy of a flowing fluid (F), which flowing fluid (F) can be supplied to the housing (4) of the fluid machine in such a way that it can be brought into flow contact with the rotor (2) for exchanging energy, and can be guided away again from the housing (4) of the fluid machine, wherein a flow-guiding element (5, 51, 52) running in a circumferential direction (U) of the rotor (2) about the rotational axis (A) is provided in the rotor space (3) between the rotor (2) and an inner wall (31) of the rotor space (3) in such a way that, in that the rotor (2) is surrounded by the flow-guiding elements (5, 51, 52) in the region of an inlet lip of the turbomachine over a predeterminable axial width (B) which approximately corresponds to the axial width of the rotor, characterized in that the flow-guiding elements (5, 51, 52) are spaced apart from the housing (4) in the direction of the axis of rotation (A) in such a way that a flow around the flow-guiding elements (5, 51, 52) on both sides is possible in the direction of the axis of rotation (A).
