Class Information
Number: 415/58.4
Name: Rotary kinetic fluid motors or pumps > With means for re-entry of working fluid to blade set (e.g., re-entry type device, passage, etc.) > Re-entry working fluid joins inlet working fluid upstream of runner
Description: Device wherein the means directs the (reentry) working fluid* portion to a location where working fluid flowing to the runner* has not yet been acted upon by the runner (i.e., upstream of the runner and prior to initial entry to the runner), at which location the (reentry) working fluid portion is merged with the working fluid flowing to the runner.
