  • Patent number: 7392777
    Abstract: The invention proposes a variable valve train (1) for a gas exchange valve (8) of an internal combustion engine, which gas exchange valve (8) is actuated by a cam (2), said valve train (1) comprising a force transmission device (4) that is arranged between the cam (2) and the gas exchange valve (8) and includes a hydraulic lifting device (9) comprising a pressure piston (10) that is arranged for longitudinal displacement in a cylinder (12), said pressure piston (10) defining a pressure chamber (13) that is connected to a pressure medium supply of the internal combustion engine and said pressure piston (10) permitting, under high-pressure loading, an actuation of the gas exchange valve (8) independently of the cam (2). The force transmission device (4) is configured as an oscillating lever or rocker arm (3) mounted for pivoting on a lever shaft (6) comprising a longitudinal channel (14) that transports pressure medium and acts as a link (15) between the pressure medium supply and the pressure chamber (13).

  • Publication number: 20070151533
    Abstract: A lever for a valve control of a piston engine is provided, which is embodied as a rocker arm, rocker lever or finger lever. A roller (6) is rotationally mounted on a support pin (7) in an intermediate space of the lever. The lateral sides (1, 2) are tapered (8, 9, 10, 16) in a region of a bore (14) which receives the support pin (7), whereby the sum of the widths (12, 13) of the lateral parts (1, 2) is smaller than a total width (11) of the intermediate space (5) enabling a counter perforation of the bore (14) to be possible.

  • Publication number: 20050235934
    Abstract: A variable mechanical valve timing mechanism for adjusting the stroke of gas exchange valves in a reciprocating-piston internal combustion engine, having a plurality of cams (5) which are fastened to a camshaft (4), having a plurality of gas exchange valves (1) and valve actuating elements (2), having adjusting units which have a plurality of adjusting elements (7) which are fastened to at least one rotatable adjusting shaft (6), having transmission apparatuses which comprise transmission elements (8), the transmission elements (8) being operatively connected to the cams (5), to the valve actuating elements (2) and to the adjusting elements (7) directly or with the interconnection of transmission members (adjusting rollers, cam rollers), and having at least one adjusting device on the rotatable adjusting shaft (6), the adjusting shaft/shafts (6) and adjusting elements (7) being configured and arranged in such a way and/or the number and position of the adjusting devices (adjusting levers 10) being selected in

  • Patent number: 6837198
    Abstract: The invention proposes a variable valve train (1) for throttle-free load control of an internal combustion engine. Each cylinder of the internal combustion engine is provided with two inlet valves (9). According to the invention, each inlet valve (9) cooperates with a particular adjusting element (8, 8a), and the adjusting elements (8, 8a) can be actuated independently of each another. This additionally enhances the variability of the valve train.

  • Patent number: 6386162
    Abstract: A fully variable valve drive (10) for throttle-free load control of an internal combustion engine is proposed. It is particularly characteristic of the invention, that a transmission component (4) is provided for a valve activation component (13) that is produced with two distinguishable parts. The one includes a lever (4a) that communicates at one end with a cam (2), and on the other hand of a catch (4b). This catch (4b) is attached at an end (5) of the lever (4a) that is away from the cam (2) in a manner that allows for pivotable movement. The catch (4b) communicates with a contact range (15) of a rotatable adjustment mechanism (9) on the one hand. On the other hand, it works on the valve activation component (13) through a swing movement. This can be influenced by assignment of the location of the rest range (15) with reference to a target (12) of the handle (4b).
