- F01L13/0036—Modifications of valve-gear to facilitate reversing, braking, starting, changing compression ratio, or other specific operations for optimising engine performances by modifying valve lift according to various working parameters, e.g. rotational speed, load, torque the valves being driven by two or more cams with different shape, size or timing or a single cam profiled in axial and radial direction
Definitions
- the second lever comprises a central bore extending opposite the central bore arranged in the first lever, the bore of the second lever comprising axially extending grooves capable of cooperating with the teeth projecting from the periphery of the ring so as to make the ring and the second lever rotate in rotation.
- the second lever 2 also comprising two arms extending perpendicular to the shaft 29 (a single arm is however shown in the figures), cooperates at its end 8 with a second control cam and by its other end with elastic return means for forcing the end 8 into contact with the second cam.
- the displacement of the shaft 294 does not immediately cause the displacement of the sleeve 40 and the ring 34, the lugs of the latter no longer being in coincidence with the corresponding recesses of the lever 2.
- the displacement of the rotation shaft 294 has the effect of compressing the spring 42 since the corresponding edge of the housing 41 has moved closer to the bush 40.
- variable distribution device such as the setting of the springs 42 and 43, or even the value of engine rotation triggering the change of cams, are adapted to each type of engine by preliminary tests conducted on engine test benches.
