Patent number: 8607767Abstract: The invention relates to a device (1) for ventilating a crankcase of an internal combustion engine, comprising a ventilation line leading from the crankcase to the suction line of the internal combustion engine, an oil-mist separator (2) for separating the oil parts from the blow-by-gases containing the oil-mist from the crankcase is arranged in the path thereof. Also, said device (1) comprises a pump (3) which is arranged upstream of the oil-mist separator (2) and which is used to produce a negative pressure. The invention is characterized in that the oil-mist separator (2) and the pump (3) are embodied as connected modules thus providing a particularly compact structure.Type: GrantFiled: May 8, 2007Date of Patent: December 17, 2013Assignee: Mahle International GmbHInventors: Stefan Ruppel, Yakup Ozkaya, Klaus Beetz, Andreas Enderich, Gerd Kissner

Patent number: 8388713Abstract: A positive crankcase ventilation oil mist separator system has a first separator unit, wherein the first separator unit includes at least one filter body arranged in a blow-by gas path such that blow by gas flows through the filter body; a second separator unit, wherein the second separator is an impactor separator arranged in a bypass path that bypasses the first separator unit; and a bypass valve, which opens the bypass path as soon as a differential pressure at the first separator unit exceeds a predefined value, wherein the second separator unit comprises an impact wall formed by a section of the filter body of the first separator unit, and a flow directing element which directs the blow-by gas flow against the impact wall when the blow-by gas path is open.Type: GrantFiled: December 9, 2008Date of Patent: March 5, 2013Assignee: Mahle International GmbHInventors: Andreas Enderich, Michael Feil, Wolfgang Früh, Ulrich Hütter, Stefan Ruppel, Hartmut Sauter, Yakup Özkaya

Patent number: 7799109Abstract: The invention relates to a device for separating a gas-liquid mixture, in which the liquid portion exists in the form of small particles, especially for ventilating a crankcase of an internal combustion engine, by separating and coagulating the liquid particles on a target area. The liquid mixture, after acceleration in acceleration openings provided for this purpose, impacts the target area at an approximately right angle. The aim of the invention is to improve the aforementioned device in such a manner that it allows as high a degree of separation as possible for different sized volume flows of mixtures. For this purpose, the number and/or the cross-sections of the acceleration openings is varied, depending on the volume flow of mixtures, between a small complete cross-section for a low volume flow and a large complete cross-section for a large volume flow.Type: GrantFiled: May 29, 2006Date of Patent: September 21, 2010Assignee: MAHLE International GmbHInventors: Robert Dunsch, Andreas Enderich, Leszek Goerlich, Stefan Ruppel, Yakup Özkaya

Patent number: 7717101Abstract: A centrifugal oil mist separator device integrated into an axially hollow camshaft of an internal combustion engine should permit a good separation effect. To this end, a device is provided whereby the camshaft (101) is provided on a first end with radial oil mist inlet openings (106) for oil mist to be introduced into the axially hollow space (102) in the camshaft (101) and on the second end, for discharge with a radial oil discharge channel (112) for oil separated as liquid phase on the one hand and with an axial gas discharge channel (113) on the other hand for oil mist stream remaining after the liquid component has been separated, a centrifugal oil mist pre-separator is provided upstream from the radial oil mist inlet openings (106) as a pre-separator (107) fixedly connected to the camshaft (101), and within the axially hollow space (102) in the camshaft (101) a spiral flow generating device (108) is provided as the final separator.Type: GrantFiled: May 6, 2006Date of Patent: May 18, 2010Assignee: MAHLE International GmbHInventors: Klaus Beetz, Andreas Enderich, Hartmut Sauter, Torsten Schellhase, Jürgen Stehlig
