Fluid energy machine

Fluid energy machine (20), comprising

• An outer casing (21), with a circular or ellipsoid inner bore (23), in cylindrical shape, at least one fluid inlet (26, 27) and at least one fluid outlet (27, 26) with a lock (37) provided between the fluid inlet (26, 27) and the fluid outlet (27, 26),
• A casing bottom (36) and a casing lid (36), each comprising a staged forced control (35) designed as a self-contained staged groove and forming a self-contained track,
• A circular turning rotational body (24) placed coaxially inside the outer casing (21), with a rotational bearing (25), with the turning rotational body (24) having several grooves (32) to take up one blade (31) each, with the respective blade (31) being attached with a radius (41) on the side towards thee inner bore (23)
• With either the turning rotational body (24) being applied with a fluid drain groove (38) each behind the multiple grooves (32) at its side towards the casing bottom (36) and the side towards the casing lid (36) to drain fluid behind the multiple blades (31) into the groove (32) when retracting the blades (31) or the casing bottom (36) or casing lid (36) being applied with a fluid drain groove (38),
• With the outer casing (21) having an inner diameter D1 that is smaller than the outer diameter D2 of the outer casing (21), and the circular turning rotational body (24) having an outer diameter D3 smaller than the inner diameter D1 of the outer casing (21), so that there is a chamber (28) between the circular turning rotational body (24) and the inner diameter of the outer casing (21) which the fluid medium enters, with the fluid entering through the fluid inlet (26, 27) into the chamber (28) draining in rotational direction through the fluid outlet (27, 26), with the flow direction of the fluid in the chamber (28) only depending on the rotational direction of the turning rotational body (24) so that the position of the fluid inlet (26, 27) referring to the position of the fluid outlet (27, 26) only depends on the turning rotational body (24) so that pumping forwards and backwards is possible,
• With the turning rotational body (24) being driven for use of the fluid energy machine (20) as a pump, causing the fluid to be conveyed through the chamber (28) by the blades (31) or acting on the fluid on the blades (31) for use of the fluid energy machine (20) as turbine, with the turning rotational body (24) being driven,
• With the blades (31) being applied with axles (33) at two opposing sides, each of which has two differently sized bearings (34) attached on top of each other that move along the track of the staged forced control (35) in the casing bottom (36) and the casing lid (36) to completely retract or extend the blade (31) in the grooves (32) with the staged forced control (35) in the casing bottom (36) being reached so that one of the two bearings (34) attached on top of each other to the respective blade (31) is used to extend the respective blade (31) and the other bearing (34) to retract the respective blade (31),
• With the blades (31) closing the chamber (28) when extended so that the fluid cannot flow back and the blades (31) can pass the lock (37) when retracted, so that a backpressure forms in rotational direction before the lock (37) that is drained through fluid outlet (27, 26) and a vacuum builds behind the lock (37) in rotational direction,
• With a lock (37) provided between the radial outer surface of the turning rotational body (24) and the radial inner surface in the inner bore (23) of the outer casing (21), and the radius (29) of the turning rotational body (24) and the radius (40) adjusted to the inner bore (23) of the outer casing (21) and the lock separating the chamber (28) between the fluid inlet (26, 27) and the fluid outlet (27, 26) to prevent flowing of the fluid against the desired rotational direction of the turning rotational body (24),
• With the staged forced control (35) retracting the blade (31) in rotational direction even before reaching the lock (37) but extending it again after passing the lock (37) while the other blades (31) entirely close the chamber (28) at the same time.
