Definitions

  • the present invention relates to an oil separation device, in particular for a crankcase ventilation of an internal combustion engine, having a hollow body axially extending in a longitudinal axis, which is flowed through by an oil-laden gas stream, wherein in the hollow body provided with an axial passage oil separation body is introduced by the gas flow can be flowed on.
  • blow-by gas In internal combustion engines and piston compressors leakage losses are observed in practice, which are due to an incomplete seal, for example, the piston-cylinder or the valve guides in the cylinder head. Leakage losses are referred to as blow-by gas and contain a significant amount of oil. With reference to internal combustion engines, it is therefore customary to conduct the blowby gas accumulating during operation of the internal combustion engine back into the intake tract of the internal combustion engine. On the one hand to minimize the loss of oil by the blowby gas and on the other hand to ensure optimum combustion and a minimum environmental impact, it is known to supply the blowby gas to an oil separator and to lead the separated oil back into the oil circuit. There is a desire to design appropriate oil separation systems as simple as possible but still reliable and efficient.
  • Another aspect of improving oil separation devices relates to a minimum flow resistance experienced by the gas flow as it flows through the oil separator.
  • a high separation efficiency is required to minimize the entry of residual oil into the charge air tract, in particular to prevent oiling of air mass meters and turbochargers.
  • the DE 10 2009 012 400 A1 shows an oil separator, which is suitable for crankcase ventilation of an internal combustion engine.
  • the ⁇ labscheide realized a hollow body, which may be formed for example by a portion of a camshaft, or the hollow body is tubular and integrated in a cylinder head cover of an internal combustion engine.
  • a swirl generator is arranged, and the hollow body has an end-side feed opening for introducing the Gas stream and a discharge opening for discharging the gas stream.
  • the gas stream introduced into the hollow body may carry oil in the form of oil mist or spray droplets which are to be removed from the gas stream by the oil separation device.
  • the cavity further comprises a discharge opening for the discharge of separated oil, which is carried out separately from the discharge of the liberated from the oil gas stream.
  • the oil separator shown uses a swirl effect, which is particularly advantageous when the oil separator is incorporated in a rotating camshaft, which forms the hollow body of the oil separator.
  • a swirl generator is provided with a plurality of spirally formed flow channels in the hollow body, through which a swirl is introduced into the oil-laden gas stream. Due to the concomitant change in the flow direction of the gas stream entrained oil droplets are deposited in the gas flow to the inner wall of the hollow body, and by the flow of the hollow body in the longitudinal direction, the oil droplets reach the outer region of the ⁇ labscheideringes, through which the gas flow in the central region of the hollow body of the oil flow in the wall portion of the hollow body is separated.
  • the oil can be separated by the discharge opening for the oil from the discharge opening of the purified gas stream, which is subsequently fed to the intake tract of the internal combustion engine or, for example, also to a reciprocating compressor.
  • this may be formed of a porous plastic or of a sintered material, wherein plastic or metal braids are advantageously used.
  • Such braids form a plurality of cavities and labyrinths, whereby the separation of the oil from the gas stream is further supported.
  • the swirl conveys the oil droplets radially outward with respect to the longitudinal axis of the hollow body, and the gas stream is passed through the central passage in the oil separation ring.
  • the object of the invention is the development of a ⁇ labscheide worn especially for the crankcase ventilation of an internal combustion engine, which has a high separation efficiency of oil made possible from a gas stream and which is further developed in particular such that the lowest possible flow resistance of the gas stream is formed by the hollow body.
  • the invention includes the technical teaching that in the region of the passage of the ⁇ labscheide endeavors a deflecting body is introduced into the hollow body, which is flowed by the gas stream substantially from the direction of the longitudinal axis with the gas stream and through which the gas flow radially outward against the inside of the ⁇ labscheide endeavors is distractible.
  • the deflection body is arranged in the area of the passage of the oil separation body in operative influence with an intermediate element, wherein the intermediate element has radial gaps through which the gas flow reaches an inner side of the oil separation body.
  • the invention is based on the idea of directing the oil-laden gas stream on the inside against the advantageously tubular or sleeve-shaped oil separation body.
  • the oil from the gas stream can be deposited on the ⁇ labscheide endeavor from the gas stream, and the gas stream can pass through the oil separator body through the example central, axial passage cleaned of the oil, the separated oil between the outside of the ⁇ labscheide endeavors and the inner wall of the tubular body can be removed , Consequently, the ⁇ labscheide endeavor forms a barrier between the separated oil and the gas stream in the further course of the gas flow, wherein the oil can be removed after passing through the ⁇ labscheide endeavors from the hollow body and the oil circuit of the internal combustion engine can be fed again.
  • the purified gas stream can be led out of the hollow body and fed to the charge air tract of the internal combustion engine.
  • the radial gaps can already be separated from one another by fan-like lamellae which, in addition to the deflection body, already upstream of the deflection body effect a deflection of the gas flow in the direction of the inside of the oil separation body.
  • the deflection of the gas stream is carried out in principle under application of a radial flow component, which superimposes the axial flow component of the gas stream in the direction of the longitudinal axis of the hollow body.

  • the deflection of the gas flow through the deflection body against the inside of the oil separation body takes place in such a way that the gas flow acts on the inside of the oil separation body approximately vertically in order to achieve a particular impactor effect.

  • an inlet funnel is arranged upstream of the passage of the ⁇ labscheide endeavors upstream, through which the gas stream is accelerated into the passage of the ⁇ labscheide endeavors inside.
  • the arrangement of the inlet funnel is achieved, in particular, that the gas stream laden with oil does not already impinge against the oil separation body on the front side.
  • the gas stream is pre-accelerated by the inlet funnel in order to have a higher speed even before deflection through the deflecting body and through the radial gaps in the holding body. Subsequently, the gas stream can be further accelerated, since there is a further flow constriction through the radial gaps against the inside of the ⁇ labscheide emotionss.
  • an opening funnel may be introduced in the hollow body, which forms a diffuser.
  • the opening funnel is open in the outflow direction, that is, the opening funnel has a larger inner diameter with increasing distance from the ⁇ labscheide emotionss and can grow up to the inner diameter of the hollow body.
  • the arrangement of the diffuser behind the ⁇ labscheide redesign can lead to a further reduction of the pressure loss of the gas flow in the opening funnel, whereby the flow resistance of the gas stream is further reduced when flowing through the ⁇ labscheide Anlagen.

  • FIG. 6 shows a partial exploded view of the oil separator 1 according to the embodiment FIG. 5 are introduced into the radial gap 19 with the flat formed hollow body 11, the flat trained oil separator 14 and the intermediate member 27 through which the gas flow can pass and the oil separation body 14 can act on from the inside.
  • FIG. 7 shows a cross-sectional view of the oil separator 1 according to the embodiment FIG. 5 in the section plane A - A and FIG. 8 shows a cross-sectional view of the oil separator 1 according to the embodiment FIG. 5 in the section plane B - B.
  • the embodiment of the flat oil separator 1 has a structure and a function, as this or this already in connection with the embodiment of FIGS. 1 and 2 described above.
  • a loaded with oil 12 gas stream 13 can be initiated.
  • the gas stream 13 flows into the intermediate element 27, which is seated in the oil separation body 14 and forms on the front side essentially an inlet funnel 20, as in connection with FIGS FIGS. 1 and 2 described above.
  • a deflecting body 15 is introduced, through which the gas stream 13 is passed through radial gaps 19 on the inside of the oil separator 14.
  • the ⁇ labscheide redesign 14 is funnel-shaped, and the funnel shape opens against the direction of the gas stream 13 and tapers downstream.
  • the oil separation body 14 is located along the longitudinal axis 10 in an axial position in front of the deflecting body 15, so that it is behind the ⁇ labscheidelik 14 and upstream of the diverting body 15, the gas stream 13 is passed through this through the radial gaps 19 on or through the ⁇ labscheideoasa 14.
  • the separation of the oil 12 takes place for a weak and for a strong flow of the gas stream 13 as in connection with the FIGS. 1 and 2 already described.
  • FIG. 7 and FIG. 8 show that the radial deflection of the gas stream 13 loaded with oil 12 takes place even in a non-rotationally symmetric deflecting body 15 in the same manner without swirling as in a rotationally symmetric deflecting body 15, because the gas stream 13 experiences no twist in the flow through the oil separator 1.
  • the flat design of Oil separation device 1 with an extension in a transverse direction Y can for example be adapted to an installation situation of the device.
  • the oil 12 is separated from the gas flow 13 either by an impactor effect upon impact and rebounding or by a filter action with a flow through the oil separation body 14.
  • FIG. 9 shows a modified embodiment with a ⁇ labscheide sensory 1, which is constructed of a separately designed inlet funnel 20, in which the gas stream 12 loaded with oil 12 flows and to which an intermediate element 27 integrally connects.
  • the intermediate element 27 is designed in the manner of a basket and has radial gaps 19 through which the gas flow 13 flows and flows against the oil separation body 14 on the inside. Depending on the flow velocity, the gas stream 13 can then impinge on or pass through only the inner surface of the oil separation body 14 until the gas stream 13 'cleaned by the oil 12 leaves the oil separation device 1 again.
  • a deflecting body 15 is internally provided in the intermediate element 27, which is flowed by the gas flow 13 from the direction of the longitudinal axis 10 and by the gas flow 13 is deflected radially outwardly to flow through the radial gaps 19.
  • the tubular ⁇ labscheide endeavor 14 is made of a non-woven material and is seated with a substantially constant outer diameter in a portion 11 'of the hollow body 11, which has a smaller diameter, so that between the ⁇ labscheide endeavor 14 and the inside of the hollow body 11 no or only a very small radially circumferential gap is present.
  • the inside of the hollow body 11 forms a baffle surface for a gas flow through the oil separation body 14 13 and for existing in this oil 12th
