Latest Patents

LeBlanc holds a patent for a "Discrete Passage Diffuser." This invention involves a centrifugal compressor that includes an impeller and a diffuser. The impeller features an inner integral hub with vanes, designed to rotate within an outer shroud about a central longitudinal axis. The diffuser, positioned downstream from the impeller, consists of multiple circumferentially spaced discrete passages that define fluid paths. These passages are angled to intersect, creating an annular semi-vaneless diffuser inlet space. Each discrete passage has an inlet and an outlet, with the outlet having a greater cross-sectional area than the inlet. This design ensures a close incidence angle match with the fluid exit angles of the impeller, optimizing performance.
