    摘要： A cam mechanism includes a cam 10 of basic circular formation and having a lobe formation 11 extending radially outwardly along part of its periphery; and a cam follower 16 mounted for reciprocating movement along an axis perpendicular to the axis of rotation of the cam 10; the cam acting against an end face 15 of the cam follower 16 so that engagement of the lobe formation 11 therewith will cause movement of the cam follower 16, the inclination of the face 15 of the cam follower 16 which is engaged by the lobe formation 11 being adjustable to vary the duration of movement of the cam follower 16 by the cam 10.

    摘要： A valve mechanism includes a poppet type valve (11), a valve lever (20) pivotally mounted at one end and attached at the other end to the end of the stem (12) of valve (11), the valve lever (20) defines a track (25) in which is located a drive pin (39) and a drive mechanism (30, 35, 37, 38) is arranged to drive the drive pin (39) in oscillatory manner; the track (25) has a first portion (28) which, when the valve (11) is closed is engaged by the drive pin (39) and coincides with the path of the drive pin (39), and a second portion (26, 27) which diverges from the path of the drive pin (39) so that when engaged by the drive pin (39) movement of the drive pin (39) will cause the valve lever (20) to move, opening and closing the valve (11). Preferably the mean position of oscillation of the drive pin (39) is adjustable so that the duration and amplitude of valve opening may be varied.

    摘要： A method and apparatus for controlling valve operation in an internal combustion engine having a crankshaft driving a cam (8) for opening and closing an intake or exhaust valve (5) which is spring-biased in a closing direction. The method comprises the steps of varying the angular phase of the crankshaft and the camshaft (8) to control the timing of the opening of the valve (5) and releasing the force applied by the cam (9) to open the valve (5) while it is being opened to control the timing of the closing of the intake or exhaust valve (5). The apparatus includes a phase control mechanism (10) disposed between the crankshaft and the camshaft (8) and a lift control mechanism (11) disposed between the cam (9) and the intake or exhaust valve (5). Both mechanisms are hydraulically operated and controlled in response to engine operating conditions.

    摘要： A valve operating mechanism for operating a single valve (1) of a particular cylinder of an internal combustion engine includes a camshaft (2) rotatable in synchronism with rotation of the internal combustion engine and having at least one cam, (4,5), and a plurality of cam followers (7-9), one of which slidably engages the cam for selectively operating the valve according to a cam profile of the cam. The cam followers are selectively interconnected and disconnected to operate the valve differently in different speed ranges of the internal combustion engine. In different embodiments, the camshaft has an annular raised portion (3) and low- (4) and high-speed (5) cams, or low-, medium-, and high-speed cams, or an annular raised portion and a cam, and the cam followers are held in sliding contact with these raised portion and cams. The valve is selectively kept inoperative by the raised portion and operated in low- and high-speed ranges by the low- and high-speed cams, or selectively operated in low-, medium-, and high-speed ranges by the low-, medium-, and high-speed cams, or selectively kept inoperative by the raised portion and operated in a high-speed range by the cam.

    摘要： Apparatus for controlling the operation of intake or exhaust valves of an internal combustion engine in which cam-driven rocker arms that operate the valves are selectively connected or disconnected for movement in unision or for independent movement in order to open and close the valves in accordance with the various modes of engine operation. Control of the valves is produced by the cooperative effect of hydraulic pressure and variable spring forces whereby more accurate valve operation over a greater number of engine operating modes is achieved.
