Turbine with Rotary Blades

A turbine with rotary blades including a rotor adapted to spin around rotor axis Z and a stator, wherein n blades evenly spaced about the axis Z protrude from the outer surface of the rotor, wherein each blade is rotational about its axis, wherein

• each blade includes a front wall and a rear wall, both of which are curved when viewed in the axis of the blade with the centre of curvature to the same side from the blade, and two lateral edges,
• wherein the turbine further comprises a pressure chamber circumscribed by a front face of the pressure chamber and a rear face of the pressure chamber from both axial directions of the turbine, an inner circumferential wall of the pressure chamber, and an outer circumferential wall of the pressure chamber,
• wherein a beginning of the pressure chamber is defined by a two-portion partition, wherein a slot is made for entry of the blade into the pressure chamber between the both portions of the partition and the blade is adapted by its shape to closely copy the shape of the slot when passing through the slot,
• wherein for each blade in a position at the exit from the slot, where the blade is located in the pressure chamber and one edge of the blade is located in the slot, the following blade is in a position at the entry to the slot, where the blade is located outside of the pressure chamber and one edge of the blade is located in the slot,
• wherein the pressure chamber comprises, in the direction of the drift of the blades, first an inlet channel for medium supply to the pressure chamber and then a sealing chamber having a length of at least α, wherein α=360°/n and a centre of the sealing chamber is located away from the slot in the direction of the drift of the blades in the range of +65° to +100° or −100° to −65°,
• wherein at each position of the turning of the rotor, the slot is sealed by at least one blade and the sealing chamber is sealed by at least one other blade.
