  • Patent number: 8225756
    Abstract: Disclosed is an adjusting mechanism for rotating the adjusting shaft of a variable valve control device for combustion engines, in which the crank of a crank-rocker mechanism or slider-crank mechanism is mounted on the camshaft and in which the rocker of the crank-rocker mechanism or the slider of the slider-crank mechanism can entrain the adjusting shaft in the desired direction of rotation by means of switchable freewheels.
    Type: Grant
    Filed: February 7, 2006
    Date of Patent: July 24, 2012
    Assignee: ThyssenKrupp Presta TecCenter AG

  • Patent number: 7302922
    Abstract: The invention is characterized in that the gas exchange valves of a cylinder are displaced in a displacement unit (15, 34) jointly and independently of the displacement of the displacement devices of the other cylinders. Every displacement unit (15, 34) is associated with separate actuators for actuating the same. Angle of rotation sensors (42, 43) are provided to detect the angle or rotation signals of the crankshaft and the camshaft or any other shaft rotating at half the crankshaft speed. These angle of rotation signals are used to derive the common idle phase of all valves of a cylinder to be jointly adjusted, a control unit (44) effecting the displacement of every displacement unit (15, 34) during said common idle phase.

  • Patent number: 7296546
    Abstract: The invention relates to a device for the variable actuation of gas exchange valves for internal combustion engines, wherein at least one cam (2) pertaining to a camshaft (1) mounted in a housing rotates according to the engine speed. The cam (2) first drives an intermediate member (4) which performs a clear oscillating, rotary movement and has a rotational axis (7) that can be displaced in the housing parallel to itself along a curve of displacement (8), said intermediate member comprising a control cam (5) having a lifting region (5b) and actuating an output member (11) that, in turn, actuates at least one valve (13). The aim of the invention is to enable one such device to be reliably controlled.
