Abstract

A regenerative blower-compressor comprises an impeller (51) mounted to a drive shaft (70) within a housing (55) including a channel (65) extending from an inlet adjacent to a low fluid-pressure region (81) of the channel (65) to an outlet adjacent to a high fluid-pressure region(82) of the channel (65), the impeller (51) extends radially outward through an annular volume (75) within the housing (55) from the drive shaft (70) to blades (80) in the channel (65), the impeller (51) is configured to rotate for rotating the blades (80) through the channel (65) for forcing fluid through the channel (65) from the inlet (66) to the outlet (67) in response to rotation of the drive shaft (70), and the drive shaft (70) extends from the impeller (51) within the annular volume (75) to into a shaft chamber (120) within the housing (55), a first port coupled in fluid communication directly between the high fluid-pressure region (82) of the channel (65) and the shaft chamber (120) for venting fluid directly from the high fluid-pressure region (82) of the channel (65) to the shaft chamber (120), and a second port coupled in fluid communication directly between the shaft chamber (120) and the low fluid-pressure region (81) of the channel (65) for venting fluid directly from the shaft chamber (120) to into the low fluid-pressure region (81) of the channel (65).
