ABSTRACT:
A volute for use in a centrifugal compressor that includes an impeller. The volute includes a housing defining a central aperture, an inlet channel, and a fluid collecting channel. The central aperture is adapted to receive the impeller such that the impeller discharges a fluid to the inlet channel. The inlet channel directs the flow to the collecting channel. A discharge portion is coupled to the housing and includes a discharge passage in fluid communication with the collecting channel to discharge the fluid. A tongue portion is disposed between the collecting channel and the discharge portion. The tongue is operable to separate the fluid into a first flow that flows through the collecting channel and a second flow that flows through the discharge passage.
