Side channel blower having a plurality of feed channels distributed over the circumference

Abstract

A side channel blower for an internal combustion engine includes a housing comprising an inlet, an outlet, a first housing part, and a second housing part. The inlet and the outlet are fluidically connected via an inlet region, via at least one feed channel which extends at least partially in an annular shape in at least one of the first housing part and the second housing part, and via an outlet region. An impeller is rotatably mounted in the housing and is driven via a drive unit. The impeller comprises conveying blades which interact with a feed channel arranged opposite thereto. At least one interruption region is arranged between the inlet region and the outlet region. The at least one interruption region is configured to interrupt the at least one feed channel in a circumferential direction. The at least one feed channel comprises a circumferential angle of <300°.

What is claimed is: 
     
         1 - 5 . (canceled) 
     
     
         6 . A side channel blower for an internal combustion engine, the side channel blower comprising:
 a housing comprising at least one inlet, at least one outlet, a first housing part, and a second housing part, the at least one inlet and the at least one outlet being fluidically connected with each other via at least one inlet region, via at least one feed channel configured to extend at least partially in an annular shape in at least one of the first housing part and the second housing part, and via at least one outlet region;   a drive unit;   an impeller configured to be rotatably mounted in the housing and to be driven via the drive unit, the impeller comprising conveying blades configured to interact with a feed channel arranged opposite thereto; and   at least one interruption region arranged between the at least one inlet region and the at least one outlet region, the at least one interruption region being configured to interrupt the at least one feed channel in a circumferential direction,   wherein, the at least one feed channel comprises a circumferential angle of <300°.   
     
     
         7 . The side channel blower as recited in  claim 6 , wherein the first housing part and the second housing part each comprise a feed channel, the feed channels comprise a common outlet, and one feed channel is smaller than the other feed channel. 
     
     
         8 . The side channel blower as recited in  claim 6 , wherein at least one of the first housing part and the second housing part comprises at least two feed channels arranged to be successive to each other in a circumferential direction, the at least two feed channels are separated by the interruption regions, and each of the at least two feed channels is connected with an outlet region. 
     
     
         9 . The side channel blower as recited in  claim 8 , further comprising at least two outlets. 
     
     
         10 . The side channel blower as recited in  claim 9 , wherein each of the first housing part and the second housing part comprises at least two feed channels arranged to be successive to each other in a circumferential direction, the feed channels which extend parallel to each other in an axial direction each comprise an outlet region, and the outlet regions end in a common outlet.
