Class Information
Number: 415/57.1
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.) > Plural, independent, serially acting re-entry means
Description: Device having two or more such (reentry) means each separately directing working fluid* which has previously contacted the first runner* blade* or blade row back to the blade or blade row. The two or more means act in sequence (i.e., one after the other) on the working fluid flowing through the device.
