Patent number: 8235014Abstract: A valve drive of an internal combustion engine, with a camshaft including cams for actuating gas-exchange valves, wherein at least one cam, which includes several cam faces, is guided nonrotatably but with freedom of axial movement on the camshaft; wherein a stroke profile, which cooperates with an actuating pin for the axial displacement of the cam or cam piece, is assigned to the associated axially displaceable cam or an axially displaceable cam piece comprising several cams; and wherein the stroke profile of the axially displaceable cam or cam piece in question includes intersecting stroke curves. A guide element is assigned to the end of the actuating pin which can be introduced into the stroke curve of the stroke profile of the associated axially displaceable cam or cam piece, this guide element being supported in such a way that it can rotate or pivot around the axis of the actuating pin.Type: GrantFiled: August 18, 2009Date of Patent: August 7, 2012Assignee: Dr. Ing. h.c.

Patent number: 4942761Abstract: An L-shaped scanning ring, which is constructed as a simple stamped metal part, can be mounted at a crankshaft web of a crankshaft after installation of the crankshaft. The scanning ring rests against the crankshaft web with both legs and, on one of the legs, carries a toothing which inductively cooperates with a stationary sensor mounted in the crankcase. The ring has a radially extending gap and, as a result, can be bent open so far that it can easily be fitted over the crankshaft. As a result of the subsequent bending-together, the scanning ring rests form-fittingly against the crankshaft web and is protected from twisting by means of pins.Type: GrantFiled: May 11, 1989Date of Patent: July 24, 1990Assignee: Dr. Ing. h.c.F.

Patent number: 4922871Abstract: An oil pump of an internal-combustion engine supplies dirty oil through a vertically extending oil feeding duct into a ring duct of an oil filter flange. From there, the oil flows through the oil filter and a central bore into a main oil duct. Since the oil feeding duct leads into the ring duct above the central bore, and the main oil duct extends above the central bore, the filter oil level, will not fall under the level of the dirty-oil inlet into the ring duct when the engine is switched off. A complete emptying of the oil filter is therefore prevented when the engine is switched off, and a fast oil pressure buildup is promoted when the engine is started again.Type: GrantFiled: August 8, 1989Date of Patent: May 8, 1990Assignee: Dr. Ing. h.c.F.
