The invention relates to a flexible blade intake valve applicable for directing the air entering the rotor of a compressor, blower or centrifugal fan The flexible blade intake valve consists of a flexible blade assembly (A), the system for synchronizing the change of blade (B) shape, the valve housing assembly (C) and the compressor, blower or fan assembly (D), where the air is sucked via an annular space (a) Then the aspirated air circulates through a space (b) confined by the flexible blade assembly (A) formed between the fix leading edges of blades (7), fixed in the outer housing (3) and the inner housing (5), the flexible or mobile trailing edges of blades (8) rotatable about an axle (9), for the mobile ones, or which can be deformed elastically at the separation zone between the fix leading edge of blades (7) and the trailing edge of blades (8), for the flexible ones The air coming out of the space (b) confined by the assembly (A) of the flexible blades with the adjusted trailing angle, with low energy losses, enters the space (c) determined by the compressor, blower or fan assembly (D), where it is compressed and then sent to the consumers
