<p>Hydraulic machine, comprising: a reservoir (2) intended to be filled with a fluid (F), and a rotor (3) freely rotatably supported about a horizontal axis (11) within the reservoir (2), the rotor (3) being so shaped that the centre (12) of buoyancy thrust to which the rotor (3) is subject when it is completely immersed in the fluid (F) is spaced apart from the axis (11) of rotation of the rotor, characterised in that it further comprises: means for varying cyclically the distance between the axis of rotation (11) of the rotor (3) and the free surface of the fluid (F) within the reservoir, when the quantity of the fluid is maintained constant, or for causing a cyclic variation in the volume of the fluid within the reservoir, when the axis (11) of the rotor (3) is fixed, and in that the rotor has a cylindrical body with a transverse section having an outline including a part of a circle with its centre located on the axis of rotation (11) of the rotor (3), and a plurality of straight segments. - (6pp) EPAB- EP-134382 B Hydraulic machine, comprising: a reservoir (2) intended to be filled with a fluid (F), and a rotor (3) freely rotatably supported about a horizontal axis (11) within the reservoir (2), the rotor (3) being so shaped that the centre (12) of buoyancy thrust to which the rotor (3) is subject when it is completely immersed in the fluid (F) is spaced apart from the axis (11) of rotation of the rotor, characterised in that it further comprises: means for varying cyclically the distance between the axis of rotation (11) of the rotor (3) and the free surface of the fluid (F) within the reservoir, when the quantity of the fluid is maintained constant, or for causing a cyclic variation in the volume of the fluid within the reservoir, when the axis (11) of the rotor (3) is fixed, and in that the rotor has a cylindrical body with a transverse section having an outline including a part of a circle with its centre located on the axis of rotation (11) of the rotor (3), and a plurality of straight segments.</p> |
