Definitions

  • the invention relates to an oil mist separator of an internal combustion engine, according to the preamble of claim 1.
  • Another Tellerstapelseparator is from the patent DE 103 38 770 B4 known, wherein a plurality of axially arranged plates form a rotor and rotate together and thus pressed due to the resulting centrifugal forces, for example, oil droplets to the outside. There they meet a substantially cylindrical gas guide ring, which surrounds the rotor radially on the outside. This basket is rotatably connected to the rotor, so that the basket rotates with the plates.
  • the object of the present invention is to provide an oil mist separator of the type mentioned in the introduction, which has a simple structural design with improved separation efficiency.
  • a ⁇ lnebelabscheider with the features of the preamble of claim 1, which is characterized in that an executed as a single part, a Prallabscheide Scheme forming hollow cylindrical Gasleitring the rotor radially outwardly surrounding, extending in the axial direction of the rotor and relative to the rotor not co-rotating inserted into the housing.
  • a rotor surrounding the outside gas guide ring is present, which is not co-rotating with the rotor. This means that the rotor rotates relative to the surrounding gas guide ring.
  • the gas guide ring forms a Prallabscheide Scheme and may be formed substantially hollow cylindrical.
  • the rotor is e.g. driven by a lubricating oil flow. Through the rotating stack of plates, the mixture of gas and oil mist receives a swirling movement and the oil is removed due to the centrifugal force to the outside and separated from the gas.
  • Such a gas guide ring can be produced in a simple manner so that the desired functionalities are fulfilled.
  • the gas guide ring may be formed fixed, for example, by being firmly connected to the surrounding housing of the centrifugal separator, or it may also be designed to be movable relative to this housing, but it does not rotate with the rotor.
  • the advantage of the invention is that the ⁇ lnebelabscheider for internal combustion engines has a simple structure and is better deposited by the relative to the rotating rotor not co-rotating gas guide ring oil from the crankcase ventilation gas.
  • the gas guide ring is movable in the axial direction of the rotor relative to the rotor and the housing, wherein the cross section of a clean gas passage between the rotor and the gas guide ring is variable by this movement.
  • a size-variable gap is formed between the gas guide ring and the rotor.
  • the cross section of the clean gas passage can be changed in the sense that the gas is smaller in the case of a smaller clean gas volume flow, the cross section of the clean gas passage is smaller and the cross section of the clean gas passage is greater for a larger clean gas volume flow.
  • the axial movement of the gas guide ring can be generated solely by a flow of the clean gas. If a slight overpressure prevails in the rotor, then the gas guide ring can be slightly raised in the axial direction by a gas flow flowing axially on the outside in order to increase the gap until a pressure equalization has been established. With decreasing volume flow, the gas guide ring automatically drops again and the gap size is reduced.
  • an upper edge is designed to be bent radially inwardly on this expediently.
  • this can at its upper edge, for example. Bent in an L-shape so as to redirect and direct the gas flow.
  • this upper edge can also be formed cranked, that is, e.g. two 90 - have deflections.
  • this is preferably acted upon by a biasing force which acts in the direction of a reduction of the cross section of the clean gas passage.
  • the force acting on the Gasleitring biasing force can be generated by gravity or by spring force.
  • At least one oil drain trough is preferably formed on the inner peripheral side on or in the gas guide ring. Due to this oil drainage channel, the oil impinging on the gas guide ring due to the centrifugal forces is discharged downwards and can no longer be removed from the clean gas flow at the top.
  • the at least one ⁇ labelitrinne runs along at least one helical line, which points in the direction of rotation of the rotor facing down.
  • the swirl of the gas flow thus supports the oil removal.
  • the oil drain trough can support oil separation through impingement and flow deflection.
  • the at least one ⁇ labelitrinne is formed by a cross-sectionally L-shaped or U-shaped profile, with an open side of ⁇ labelitrinne facing down.
  • the oil drain trough is stable and contributes to the stability of the gas guide ring.
  • a favorable injection molding production in this design is possible. Inside this ⁇ labelitrinne the oil is largely protected against entrainment by the rotating gas flow.
  • the gas guide ring can form a closed, perforation-free surface.
  • the gas guide ring may then be e.g. be formed by a one-piece hollow cylinder made of plastic or metal.
  • the gas guide ring may form a perforated or porous surface to receive oil therein.
  • the gas guide ring may be formed by a hollow-cylindrical lattice or sieve or filter material body.
  • the at least one ⁇ labelitrinne is advantageously molded onto the gas guide ring.
  • At least one support ring preferably two axially spaced apart and circumferentially circumferential support rings, is molded onto the gas guide ring except the at least one ⁇ labelitrinne /.
  • the lattice or screen or filter material body forming the gas guide ring consists of a non-self-supporting element made of woven or knitted fabric or knitted or knitted fabric, preferably of textile material, or of open-cell foam, each with an integrated support body, or a self-supporting element of a woven or knitted fabric or scrim or knit, preferably of metallic material, or of sintered material.
  • the grid or sieve or filter body forming the gas guide ring has a mesh or pore size between 10 and 300 ⁇ m.
  • an oil discharge annulus be kept free between an outer circumferential surface of the gas guide ring and an inner circumferential surface of the housing.
  • a deflection ring is attached or formed, which points against a present gas flow direction in the interior of the housing. Due to the deflection ring, the gas flow is forced to a sharp deflection, which can not follow the oil particles. The oil particles catch rather radially outside of the deflection ring and can be discharged from there down.
  • two separate annular spaces are formed in the housing between the inner peripheral surface of the housing and the rotor.
  • this is a first annular space between the rotor and the gas guide ring, through which substantially the clean gas is discharged, which does not or hardly passes through the gas guide ring to the outside.
  • a second annular space through which the oil is discharged.
  • a labyrinth seal can be formed between a housing wall of the separator and the gas guide ring, which substantially inhibits the passage of a gas flow, so that this second, outer annular space is kept free of turbulence.
  • FIGS. 1 and 2 In each case, an oil mist separator 1 of an internal combustion engine with a rotor 2 in the form of a stack of plates is shown, wherein a plurality of plates 20 form the rotor 2, which can be set in rotation by a rotary drive 23. Of the Rotor 2 is in this case arranged in a housing 10 of the oil mist separator 1.
  • the stack of plates 20 is below and top side of a stacking pedestal 24 and a stacking cap 25 enclosed.
  • a spring 26 presses the stacking attachment for fixing the plate 20 down.
  • a shaft 21 carries the rotor 2 and is mounted in an upper bearing 22 and a lower bearing 22 '.
  • a base plate 16 bounds the housing 10 on the underside. With this underside of the oil mist separator 1 can be flanged as a unit with the interposition of seals 17 by means of screws 18 to an internal combustion engine.
  • the shaft 21 passes through the base plate 16 down through and carries there the rotary drive 23rd
  • crankcase ventilation gas is introduced from below into a space region 12, then flows radially inwardly from bottom to top in the rotor 2 and then between its plates 20 radially obliquely outward.
  • entrained oil particles are deposited on the plates 20 as a result of centrifugal force action.
  • the separated oil flows radially outwards on the underside of the plate and is thrown off radially outwards.
  • the clean gas is discharged upward in a space area 13, to which, as shown in the examples, a crankcase pressure control valve 4 can connect. From there, the clean gas flows out through the gas outlet 40, e.g. to the intake manifold of an associated internal combustion engine.
  • the separator 1 has a surrounding gas surrounding the gas guide ring 3 wherein the gas guide ring 3 is formed such that it does not rotate with the rotor 2. He may either be arranged spatially fixed and, for example, be firmly connected to the housing 10 or he may be used loosely.
  • the gas guide ring 3 can be raised slightly by the flow pressure, so that the clean gas passage 32 increases until a pressure equalization is obtained.
  • the provision of the gas guide 3 down is done by gravity. If necessary, for this purpose, the gas guide ring 3 can be acted upon by a spring force.
  • the upper edge 31 either as shown, bent L-shaped, or be cranked so as to form a groove, so that the leakage of lubricating oil is effectively prevented at this edge 31.
  • the gas guide ring 3 is omitted or not yet installed.
  • the housing 10 in FIG. 2 on the inside in the amount of the radially outer edge of the stacking cap 25 has a deflection ring 11 '.
  • the deflection ring 11 ' points downwards and forms a sharp flow deflection for the upwardly flowing gas flow, whereby any oil particles still contained in it are separated. These oil particles then flow downwards on the inner circumferential surface 11 of the housing 10.
  • FIGS. 3 and 4 show a gas guide 3 as a single part in plan view and in longitudinal section.
  • On the inner peripheral surface 30 are distributed in the circumferential direction several ⁇ lableitrinnen 33 with helical course.
  • oil drainage channels 33 In addition to the oil drainage channels 33 also form means for impact separation of oil and flow control.
  • the gas guide ring 3 can consist of a hollow-cylindrical element 34, for example of a woven fabric or the like, which is held in shape by means of a support body 34 '.
  • FIG. 5 shows a Gasleitring 3, which is designed as a self-supporting, hollow cylindrical member 35, for example of a sintered material.
  • the gas guide ring 3 is smooth on its inner circumference, that is executed without ⁇ lableitrinnen, because the material absorbs the oil and then passes the oil in its interior down.
  • FIGS. 6 and 7 show two other versions of the gas guide 3 each as a single part in longitudinal section.
  • On the inner circumferential surface 30 are distributed here in the circumferential direction several ⁇ lableitrinnen 33 with helical course.
  • the gutters 33 serve here as a means for impact separation of oil and for flow control.
  • the ⁇ lableitrinnen 33 are L-shaped and open axially downwards.
  • the upper edge 31 is formed in both gas guide rings 3 as a reinforcement and also has radially inward ⁇ lfangrinnenabitese 38, which are open axially downwards and extending between each two adjacent ⁇ lableitrinnen 33 in this or one of these.
  • the gas-conducting ring 3 is intercepted by the gas flow during operation of the oil-mist separator on the inner circumferential surface 30 and transported up into the oil-drainage grooves 33.
  • the gas guide ring 3 consists of a hollow cylindrical plastic body, which is produced in one piece with the ⁇ lableitrinnen 33 and the ⁇ lfangrinnenabroughen 38 as an injection molded part.
  • the gas guide ring 3 is formed by a non-supporting element 34, for example made of a fabric or the like, which is held in shape by means of a support body 34 '.
  • the support body 34 ' in this case comprises the ⁇ lableitrinnen 33 and the ⁇ lfangrinnenabête 38 and is integrally manufactured as an injection molded plastic part.
  • the element 34 made of fabric or the like can be injection-molded immediately onto the support body 34 'during an injection process or, alternatively, can be subsequently connected to the support body 34'.
