摘要： The present invention relates to an internal combustion engine (1, 1 B) for a motor vehicle having a ridable seat, wherein said engine (1, 1 B) comprises a device (2) for changing the timing of the suction or relief valves (110, 220) with respect to said drive shaft (300). Such a device comprises a first disc (11) idly mounted to said camshaft (10) and comprising a first side (11 A) defining first slot tracks (31). The device further comprises a second disc (12) which is integral with the same camshaft (10) and comprises second slot tracks (32) facing said first side (11 A) of said first disc (11), wherein each of said second tracks (32) partially faces a corresponding first groove (31 ) of said first disc (11 ); a plurality of drive elements (40) for transmitting the motion between said first disc (11 ) and said second disc (12), wherein said drive elements (40) are interposed between said discs (11, 12) and each is accommodated between corresponding two of said partially facing tracks (31, 32), and wherein as the centrifugal force caused by the rotation speed of said camshaft (10) changes, each of said drive elements (40) moves between a first reference position and a second reference position which are close to and far from the rotation axis of said camshaft (10), respectively. According to the invention, the phase changer device comprises means (6) for retaining said drive elements (40), wherein said retaining means (6) are operatively interposed between said first disc (11) and said second disc (12) and exert a force which tends to oppose the movement of said drive elements (40) towards said second reference position.

摘要： The invention relates to an internal combustion engine (1, 1B, 1C, 1D) for a motor vehicle having a ridable seat, comprising at least a first centrifugal device (2, 2B) for varying the timing of a first plurality of suction or relief valves (110, 220) with respect to the drive shaft (300). Such a device comprises a driving disc (11, 11B) mounted idle on a first camshaft (10, 20) which controls said plurality of valves, and at least one driven disc (12, 12B) which is integral with the same camshaft (10, 20). Drive elements (40) for transmitting the motion from the driving disc (11) to the driven disc (12, 12B) are interposed between the two discs (11, 12) so as to cause a relative rotation of the driven disc (12, 12B) with respect to the driving disc (11, 11B) when the rotation speed of the discs (11-12, 11B-12B) exceeds a predetermined threshold. The engine also comprises a distribution system (5) which mechanically connects the drive shaft with the driving disc (11, 11B) so as to cause the rotation thereof. According to the invention, the engine comprises a first gear (15) which is integral with the driving disc (11, 11B) and a second gear (16) mounted on a second camshaft (10, 20) so that the rotation of said second gear (16) directly or indirectly causes the rotation of said second shaft. Such second gear (16) meshes with the first gear (15) so that the rotation of the driving disc (11, 11B) mounted on the first camshaft causes the rotation of the second camshaft (10, 20) selected to control the other plurality of (relief or suction) valves (110, 220) of the engine.
