US Patent 11603860 Radial compressor having iris diaphragm mechanism

A radial compressor having a specially designed iris diaphragm mechanism is described. This mechanism includes only a single (main) blade that is driven directly by an actuating element, while the other blades are driven by the respective preceding blade via the movement of the main blade. This results in a particularly simple embodiment of the iris diaphragm mechanism. A blade for an iris diaphragm mechanism of this type and a charging device having a radial compressor of this type are furthermore described.
