Centrifugal turbine for breathing-aid devices

An electric turbine (1) comprising a turbine rotor (4, 7), a turbine stator (2, 3), and electric motor member (5, 6) intended to drive the rotor (4, 7) rotationally with respect to the stator (2, 3), wherein

• the turbine stator (2, 3) comprises a stator body defining a generally toric compression chamber (12) provided with an annular opening;
• the turbine rotor (4, 7) comprises a set of blades (26, 27) extending generally radially from a central air inlet formed by an annular intake duct (11) to the annular opening of the compression chamber (12) of the turbine stator (2, 3), this set of blades (26, 27) being fixed to a shaft (4) mounted coaxially able to rotate in the turbine stator body;
• the electric motor member (5, 6) comprises a toric motor stator (6) housed and fixed in a motor housing (16, 23) of the turbine stator (2, 3), at the centre of the toric compression chamber (12), and a motor rotor (5) mounted and fixed on the turbine rotor shaft (4), axially opposite the motor stator (6).
