Patent number: 7845322Abstract: The present invention relates to a cylinder head cover (4) for covering a cylinder crank case (14) of an internal combustion engine. It is essential to the invention here that at least one bearing upper part (3) for a camshaft (2) has at least one through-opening (5), which is in alignment on the one hand with a screw-in/through-opening (5a) in a bearing lower part (6) and/or with a screw-in opening (5b) in the cylinder crank case (14) and on the other hand with a through-opening (5c) in the cylinder head cover (4), so that it is possible to fasten the cylinder head cover (4) and the bearing upper part (3) on the cylinder crank case (14) by means of a shared fastening screw (7), in which the cylinder head cover (4) is produced from a material which has different material characteristics from the at least one bearing upper part (3).Type: GrantFiled: May 29, 2008Date of Patent: December 7, 2010Assignee: Mahle International GmbHInventors: Robert Dunsch, Stefan Ruppel, Torsten Schellhase

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

Patent number: 7434572Abstract: The invention relates to a cylinder head (1) of an internal combustion engine with a camshaft bearing mechanism (2) situated thereon in which a hollow camshaft (3) is rotatably mounted, forming an outlet for discharging blow-by gases laden with oil droplets out of the crankcase and is designed as an oil droplet separator for separating the oil content out of these gases. The camshaft (3) passes through a valve space (11). A rocker cover (13) or a multichannel device (27) is connected axially to at least one end of the camshaft (3), forming an axial gap (9), each having a channel (10) connected coaxially to the hollow space (5) of the camshaft (3) so that blow-by gases from which the oil has been removed can be discharged from the camshaft (3), and each being designed so that they either form an oil collecting space (12) that is sealed with respect to the valve space (11) or they introduce oil that has been separated into such an oil collecting space (12).Type: GrantFiled: March 9, 2007Date of Patent: October 14, 2008Assignee: MAHLE International GmbHInventors: Ulrich Hütter, Torsten Schellhase

Patent number: 5595146Abstract: A combustion engine. The engine includes an engine housing; at least one cylinder disposed in the engine housing; and a crank drive including: a crankshaft having a crank; and a piston being axially displaceable within the cylinder. The crank drive further includes a connecting rod which has an upper connecting rod part hinged to the piston; and a lower connecting rod part hinged to the crank. The lower connecting rod part is hinged to the upper connecting rod part. A central joint hinges the upper connecting rod part and the lower connecting rod part to one another, a longitudinal axis of the upper connecting rod part further being defined by a line connecting the central joint with a hinge joint of the upper connecting rod part to the piston.Type: GrantFiled: January 24, 1995Date of Patent: January 21, 1997Assignee: FEV Motorentechnik GmbH & Co.
