Patent number: 6382149Abstract: A valve timing gear of an internal-combustion engine is provided, in the case of which a camshaft acts by a timing cam upon a valve by way of a tappet whose cam-side contact path can be changed by a control device for changing the valve opening period. For achieving a small-sized control device, this control device comprises a slider rocker guided in the valve lifting direction by way of a first sliding hinge joint arranged on an engine section side and an additional sliding hinge joint provided on the tilting segment side, with a control opening penetrated with play by a timing-cam-free section of the camshaft. An element, which can be operated in a controlled manner, of an adjusting device is arranged in/on the camshaft, while rotating with it, and being applied such to the circumference of the control opening that the adjustable slider rocker, while the camshaft is rotating, carries out for each valve lift a periodic rocking movement which is used for forcibly controlling the tilting segment.Type: GrantFiled: February 5, 2001Date of Patent: May 7, 2002Assignee: Bayerische Motoren Werke AktiengesellschaftInventors: Gert Fischer, Michael Bidlingmaier, Johannes Hoehl

Patent number: 5732669Abstract: An internal combustion engine has a camshaft with control cams which act on respective valves through a transmission member whose contact path on the cam side is variable in its position relative to the control cam via a control device for changing the valve opening period with a valve lift that is essentially constant. To achieve exact control, the contact path is formed on a roller, which is forcibly controlled relative to the drag lever in synchronization with the camshaft, as an intermediate element between the control cams and the drag lever.Type: GrantFiled: December 23, 1996Date of Patent: March 31, 1998Assignee: Bayerische Motoren Werke AktiengesellschaftInventors: Gert Fischer, Johannes Hoehl
