摘要： A combustion engine for a vehicle includes a first centrifugal device for varying timing of a first plurality of suction or relief valves with respect to the drive shaft. A driving disc is mounted idle on a first camshaft which controls the valves, and at least one driven disc is integral with the camshaft. Drive elements for transmitting motion from the driving disc to the driven disc are interposed between the two discs causing a relative rotation of the driven disc with respect to the driving disc when the rotation speed of the discs exceeds a predetermined threshold. A distribution system connects the drive shaft with the driving disc so as to cause the rotation thereof. A second gear meshes with a first gear so that rotation of the driving disc mounted on the first camshaft causes the rotation of the second camshaft to control other valves of the engine.

摘要： A parking brake includes an inhibitor device (31), which can be associated with a drive shaft (3) for rotating therewith, the inhibitor device (31) being actuated by centrifugal force. The parking brake further includes a locking member (33) adapted to engage the inhibitor device (31) when actuated. The inhibitor device (31) is configured to prevent the engagement of the locking member with the inhibitor device when the inhibitor device rotates at a speed greater than a minimum speed, so as to prevent the application of the parking brake.

摘要： A combustion engine for a vehicle includes a device for changing the timing of suction/relief valves with respect to the drive shaft. The device includes a first disc idly mounted to the camshaft and has a first side defining first slot tracks. A second disc is integral with the camshaft and includes second slot tracks facing the first side of the first disc. Drive elements transmit motion between the first disc and the second disc and each is accommodated between corresponding two of the partially facing tracks. As centrifugal forces caused by the rotation speed of the camshaft changes, each drive elements moves between a first reference position and a second reference position which are close to and far from the rotation axis of the camshaft, respectively. A phase changer device exerts a force which tends to oppose movement of said drive elements towards the second reference position.
