Definitions

  • the invention relates to a side channel blower for an internal combustion engine having a multipart housing, in which an axial inlet, which opens into an at least one substantially annularly extending delivery channel via an inlet region and an outlet is formed, an impeller, which is drivable via a drive unit, is rotatably mounted in the housing and having conveying blades, which cooperate with the opposite conveying channel, and an interruption area between the inlet and the outlet, in which the at least one conveying channel is interrupted in the circumferential direction, wherein the at least one conveying channel leads in a tangential direction to the outlet , wherein an outlet opening extends in the radially limiting wall in the direction of rotation of the impeller to an outlet edge, wherein in the direction of rotation of the impeller immediately behind the outlet opening at the radially delimiting wall a recess madbil is det, which reduces the expansion of the interruption region on the radially delimiting wall in the circumferential direction.
  • Such a device is from the US-A-2 217 211 known.
  • the extension of the outlet opening in the direction of rotation of the impeller grows from the conveyor channel in a second housing part in the direction of a cover part, in which the inlet is formed.
  • the flow vector of an eddy in the region of the outlet is modeled, whereby an additional emptying of the pockets is achieved.
  • a recess 60 is formed immediately behind the outlet opening 58 at the interruption area 32 of the radially delimiting wall 33.
  • This recess 60 is bounded by a breaker edge 66 in the direction of rotation of the impeller 4, which also extends from the bottom of the housing part 16 obliquely above, that has an axial component in the direction of the cover part 10 and a component in the direction of rotation of the impeller.
  • the breaker edge 66 and the outlet edge 62 are not parallel but at an angle to each other, wherein for the outlet edge 62, the component in the direction of rotation is greater than for the breaker edge 66. It should be noted that with a greater distance between the blades 22 of the Impeller 4 also included Angle between the interrupt edge 66 and the outlet edge 62 should be selected larger.
  • the velocity vector of this residual air has a component radially outward, a component in the direction of rotation of the impeller 4 and a component in the direction of the cover part 10.
  • the component of the air flow in the circumferential direction substantially corresponds to the speed component of the impeller 4. It follows that due to the selected maximum extent of the outlet opening 58 in the direction of rotation does not abut the air flowing out of the pocket 28 against the outlet edge 62 of the outlet opening 58 in the form of a pressure surge, but flows into the outlet 20.
