Definitions

  • the invention relates to a centrifugal separator for separation of oil from a gas stream, especially for ventilation of the crankcase of an internal combustion engine in the Preamble of claim 1 specified genus.
  • a centrifugal separator is known from DE 198 03 872 A1, of a housing with baffles arranged in it Has flow diversion.
  • the centrifugal separator is firmly connected to and is driven by a drive shaft driven in rotation.
  • To get the cleaned gas from that too Separating the cleaning gas is the sealing of the rotating housing opposite adjacent, fixed Components necessary. However, the necessary sealing hides the risk of leakage.
  • the invention has for its object a centrifugal separator of the generic type to create the is simple and reliable.
  • the housing of the centrifugal separator is held against rotation.
  • Impeller arranged to rotate around the longitudinal axis of the drive shaft, the paddles having a centrifugal flow produce.
  • the gas outlet formed in the housing thus does not have to be compared to components that are moved relative to it be sealed.
  • the impeller rotates without contact the housing, so that relative movements and the associated Wear are avoided. At the same time it results a simple structure of the centrifugal separator.
  • the gas inlet on the circumference of the drive shaft is advantageous arranged between the housing and the drive shaft and surrounds the drive shaft completely.
  • the gas is admitted approximately parallel to the longitudinal axis of the drive shaft.
  • the longitudinal axis of the drive shaft extends the width of the housing in a region between the gas inlet and the outer periphery the blades decrease radially outwards.
  • the partition extends radially from the drive shaft outwards to the outer circumference of the blades. An increase the pressure built up on the circumference of the housing results, if on the side of the partition facing the gas outlet blades producing a centripetal flow are arranged are.
  • the drive shaft is in particular the camshaft or balance shaft of an internal combustion engine.
  • Advantageous is the housing on the cylinder head of an internal combustion engine formed.
  • centrifugal separator results itself when the drive shaft is axially spaced in the housing ends from a housing wall.
  • the one with the impeller The end of the drive shaft is thus self-supporting.
  • the gas outlet is expedient compared to the gas outlet facing blades offset radially inwards.
  • the Oil outlet is arranged in particular on the circumference of the housing.
  • the centrifugal separator 1 shown in the figure has a housing 2, which is arranged rotatably.
  • the housing is particularly on the cylinder head of an internal combustion engine formed.
  • the housing 2 is largely rotationally symmetrical to the longitudinal axis 4 of a drive shaft 3.
  • the housing 2 has a front wall 18 which in Bulged direction on the longitudinal axis 4 of the drive shaft 3 is.
  • the longitudinal axis 4 simultaneously represents the Axis of symmetry of the housing 2.
  • In the area of the drive shaft 3 has the front wall 18 of the housing 2 arranged concentrically to the longitudinal axis 4, in particular circular opening 17. Through opening 17 the drive shaft 3 protrudes into the housing 2.
  • an intermediate space is formed, which is circular between the outer circumference of the Drive shaft 3 and the opening 17 extends and the Gas inlet 5 forms.
  • An impeller 14 is rotatably fixed within the housing 2 the drive shaft 3 connected.
  • a partition 8 perpendicular to the longitudinal axis 4 of the drive shaft 3 radially extends outside.
  • the partition 8 is thus approximately disc-shaped educated.
  • On the gas inlet 5 facing Side 9 of the partition 8 has the impeller 14 blades 11 which are in particular approximately parallel to the longitudinal axis 4 extend radially outwards and the one centrifugal flow produce.
  • the blades 11 run parallel to the front wall 18 of the housing 2.
  • the partition 8 extends to about the outer circumference 13 of the blades 11.
  • an oil outlet 7 On the outer circumference 16 of the Housing 2 is an oil outlet 7 which is slit-shaped and parallel to the longitudinal axis 4 of the drive shaft 3 extends. Between the outer periphery 16 of the housing 2 and An annular space 24 is formed on the outer circumference 13 of the blades 11.
  • blades 12 are arranged on the impeller.
  • the shovels 12 extend in a narrow range from Outer circumference 13 of the blades 11 radially inwards.
  • the gas outlet 6 is radial to the longitudinal axis 4 within the Scoops 12 arranged and closes in particular in radial direction directly on the blades 12.
  • the shaft end 19 of the Drive shaft 3 has the rear wall 15 of the housing 2, in which is also the gas outlet, an axial Distance a.
  • the drive shaft 3 with the impeller 14 is thus Movable in the housing 2 without contact.
  • the distance d between the partition 8 and the rear wall 15 of the housing is constant, while the distance c between the partition 8 and the Front wall 18 of the housing 2 in a region of the partition 8 decreases radially outwards.
  • the distance c on the However, gas inlet 5 facing side is on each Place larger than the distance d on the gas outlet 6 facing page 10.
  • the drive shaft rotates 3 in the direction of arrow 20 about the longitudinal axis 4.
  • Gas to be cleaned flows approximately in the direction of arrow 21 axially into the housing 2 and into the region of the impeller 14 and is radially turned by the rotation of the impeller 14 accelerated outside.
  • pressure builds up in the gas. This will drain oil separated from the gas and flows through the oil outlet 7 in the direction arrow 22 out of the housing 2.
  • the cleaned gas flows on the gas outlet 6 facing side 10 of the Partition 8 and from there through the gas outlet 6 in the direction arrow 23 out of the housing 2.
  • Centrifugal separator 1 used as a pre-separator become.
  • the Centrifugal separator 1 used as a pre-separator become.
  • the Centrifugal separator 1 At higher speeds or by enlarging of the diameter of the impeller 14 and the housing 2 also suitable for use as a final separator.
  • About the Dimensioning and the adjustment of the speed can Centrifugal separator 1 to the required separation capacity be adjusted.
