Patent number: 9598992Abstract: A separation device for separating contaminates from a gas flow may include a raw chamber receiving a contaminated gas and a clean chamber out of which a treated gas exits. A dividing wall may separate the raw chamber from the clean chamber. The dividing wall may include a perforated region defining a plurality of passage openings. The gas flow may be communicated from the raw chamber to the clean chamber via the plurality of passage openings. A gas-permeable separation structure may be arranged on a wall outlet side of the dividing wall facing the clean chamber. The separation structure may separate contaminates from the gas flow when subjected to a through flow.Type: GrantFiled: December 17, 2013Date of Patent: March 21, 2017Assignee: Mahle International GmbHInventors: Stefan Ruppel, Julius Aktas, Yakup Oezkaya, Leszek Goerlich, Ulrich Wiesner, Jan Scheffel

Patent number: 8893688Abstract: The present invention relates to a device for venting a crank space in an internal combustion engine (1) having a suction device (5) for sucking out blow-by gases from the crank space (3) and having a venting line (4) which leads from the crank space (3) to the suction device (5) and in the course of which a throttle device (6) or a pressure regulating element (7) is arranged in order to bound a partial pressure which is generated by the suction device (5) in the crank space (3). It is essential to the invention here that an oil mist separator (8) which is embodied as an impactor is integrated into the throttle device (6) or into the pressure regulating element (7).Type: GrantFiled: August 31, 2007Date of Patent: November 25, 2014Assignee: Mahle International GmbHInventors: Stefan Ruppel, Yakup Özkaya, Leszek Goerlich

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
