Latest Patents
Roberts' latest patents include the "Discrete Passage Diffuser." This invention involves a centrifugal compressor that features an impeller and a diffuser. The diffuser is designed with a plurality of discrete D-shaped passages that intersect each other. The impeller has an inner integral hub with vanes and is adapted to rotate within an outer shroud about a central longitudinal axis. The defined hub-to-shroud distribution of fluid exit angles enhances the efficiency of the compressor. The diffuser, located downstream from the impeller, comprises circumferentially spaced discrete passages that partially define fluid paths. These passages are angled to intersect, forming an annular semi-vaneless diffuser inlet space. Each discrete passage has an inlet and an outlet with a greater cross-sectional area than the inlet, optimizing fluid flow. The design ensures that the leading edge of each discrete passage matches the fluid exit angles of the impeller closely.
