    摘要: A valve actuating mechanism is proposed for an internal combustion engine in which at least one intake valve E is actuatable optionally by a low-speed cam 2 or a high-speed cam. The first rocker lever 5 operates in conjunction with the low-speed cam 2 and the valve E, while the second rocker lever 8,9 operates in conjunction with the high-speed cam 7 and can be connected to the first rocker lever by means of a coupling bolt 12 mounted in a bore 10 of the first rocker lever 5 which is aligned with a bore 11 in the second rocker lever 8, 9 when both rocker levers are riding on the base circles of their cams. The coupling bolt 12 is moved into the coupling position against the force of a spring 17. The spring 17 rests on one side on the end of a pipe 20 connected to the coupling bolt 12 and on the other side on an insert 18 introduced into the bore 10, the pipe 20 extending through this insert 18. In order to achieve brief switching periods, the pipe 20 is provided in the vicinity of the reverse side 31 of the coupling bolt 12 with a cross hole 28 through which quick pressure increase and decrease on the reverse side 30 of the coupling bolt 12 is effected.

    摘要: In a multi-cylinder internal combustion engine, the cylinders are disposed in two rows, the cylinders in one row being staggered with respect to the cylinders in the other row and the longitudinal axes of the cylinders in the first row being disposed at an angle to the longitudinal axes of the cylinders in the other row. The outlet valves are located close to the plane of symmetry between the rows of cylinders whereas the inlet valves are located out of this plane. All of the outlet valves of both rows of cylinders are provided with a common centrally located camshaft whereas the inlet valves of each row of cylinders is provided with a dedicated sidelocated camshaft for each row.

    摘要: A double-flow butterfly valve part (1) contains two butterfly valves (4 and 6), which are connected together by means of a coupling element (10). The second butterfly valve (6) is opened only when the first butterfly valve (4) is moved beyond a partially open position into the completely open position. To make it possible to shift the two butterfly valves (4 and 6) back by means of a single restoring spring acting on the first butterfly valve (4), a desmodromic control is provided between the coupling element (10) and the second butterfly valve (6). For this purpose, a lever (9) is disposed on the shaft (7) of the second butterfly valve (6). This lever (9) contains an arched slot (12), which is engaged by a roller (13) mounted in the coupling element (10). The coupling element (10), in turn, is provided with an arched slot (14), which is engaged by a roller (15) mounted in the lever (9).

    摘要: An actuating mechanism for three inlet valves of a cylinder of an internal combustion engine has three first rocker arms, each of which actuates an inlet valve and is actuated by a first cam for a lower revolution speed range, and two second rocker arms which are arranged between adjacent first rocker arms and are actuated by second cams for the upper speed range. The first and second rocker arms are coupled in the upper speed range so that the valves are actuated in accordance with the contour of the second cams.

    摘要: A valve mechanism for an internal-combustion engine with at least two valves 1 per cylinder which can be actuated by cams 2, 7 of a camshaft 3 via rockers 4, 6. The rockers are mounted pivotally next to one another on a common fixed shaft 5, and they bear with sliding surfaces 8 against their cams. The rockers are pressed against one another by a spring 10, and their sliding surfaces 8 are aligned at least intermittently with one another and then form an essentially continuous surface. The camshaft 3 has a longitudinal channel 13 which is connected to a lubricant source and from which extends, for the lubrication of a plurality of sliding surfaces, a lubricating-oil bore 14 which opens out on the circumferential surface of a cam 7 cooperating with one of these sliding surfaces.

    摘要: A drive arrangement for a camshaft (3) of an internal combustion engine is fitted with a facility for rotating the camshaft (3) relatively to a coaxial drive wheel (5) having a switching component (6), which interacts via a spur toothing (7) with the drive wheel (5) and via a helical gearing (8) with the camshaft (3) and can be axially shifted by a servo motor (13). The servo motor (13) is disposed at the end of the camshaft averted from the drive wheel (5). This prevents the axial length of the internal combustion engine from being extended beyond the drive wheel (5) by the servo motor.

    摘要: A drive arrangement for a camshaft 2 of an internal combustion engine comprises a device for rotating the camshaft 2 relative to a drive wheel 5. This device has a gear-change sleeve 11 coaxial with the camshaft 2 and axially mobile between two end positions, which is connected, on the one hand, to the drive wheel 5 by a spiral gear 12, 13 and, on the other, to the camshaft 2 by a straight gear 15, 16. To obtain a compact arrangement and to allow one and the same cylinder head to be fitted with either an ordinary camshaft or a camshaft drive with variable valve control times, the camshaft 2 ends in the direction of the drive wheel 5, after a cam 3a, and the support bearing 9, which in an ordinary camshaft serves to support the camshaft between the last cam and the drive, is used to support the hub part 7 of the drive wheel 5. On the other side, the drive wheel 5 is supported over an second hub part 8 in an additional bearing 10 in the cylinder head 1, the bearing opening of which is closed off by a cover when an ordinary camshaft is used.
