A recently granted patent (Publication Number: US11971053B2) discloses a rotor design for a fluid machine, featuring a wheel supported for rotation about an axis of rotation with a plurality of blades. The rotor includes a unique balancing mark recessed into the inter-blade area surface, defined by an elongate and arcuate shape with varying depth and width along its length. The balancing mark is strategically positioned between two blades, with one end near the pressure side of the first blade and the other end near the suction side of the second blade. This design aims to improve the overall balance and performance of the rotor within the fluid machine.

Furthermore, the patent also covers a fluid charger device incorporating the rotor design within a housing. The device includes a wheel with a face extending radially from the axis of rotation, with the balancing mark recessed into the inter-blade area surface. The unique shape and positioning of the balancing mark, along with the presence of fillets at transitions between blades, contribute to enhancing the efficiency and stability of the fluid charger device. By focusing on the intricate details of the rotor design, the patent aims to optimize the performance of fluid machines and charger devices, offering a novel solution in the field of rotor technology.
