摘要： The invention proposes a tubular camshaft (10) for a motor vehicle combustion engine, which camshaft comprises at least an oil-circulation bore (12) of a determined first diameter (D
12 ), supplied with oil (H) at a first end (14) via a coaxial supply orifice (16) and extending substantially along the length of said shaft (10), and which comprises a plurality of radial ducts (18) which are distributed along the length of the shaft (10), which pass through a tubular wall (20) of the shaft (10), and which place the inside of the bore (12) in communication with the outside of the shaft (10), characterized in that the bore (12) is closed at a second end (26) the opposite end to the first end (14) and in that each radial duct (18) comprises, inside the bore (12), an inlet end (28) which is arranged at a second diameter (D
28 ) smaller than the first diameter (D
12 ) so as, as the shaft (10) rotates, to form a spillway able to allow oil (H) to be discharged by centrifugal spinning and impurities (24) to be held within the bore (12).

摘要： The invention relates to a system (10) for offsetting the rotation of two shafts mounted with the ability to rotate about axes that are substantially parallel and that are connected by transmission means (18) passing around coplanar toothed wheels (15, 17) each borne by one shaft. The system (10) comprises a movement device (23) for moving at least one of the branches (20, 22) of the transmission means (18), which device is configured to cause the positions of the two branches (20, 22) to vary. The system comprises a first mobile pressing element (24) made to press against one branch (22) the movement of which is brought about by an actuating element (26), and a second mobile pressing element (25). The system (10) also comprises at least two damping elements (29, 33) configured to reduce the dynamic forces experienced by the movement device (23) and generated by the transmission means (18).

摘要： A piston top (10) for an internal combustion heat engine, comprises an upper face (11) intended to be turned towards a cylinder head (12) provided in the top part of a combustion chamber (13) delimited in the lower part of same by said piston top (10), said upper face (11) comprising a cavity (14). Said cavity (14) has a shape such that, at any point in the depth (H) of the cavity (14), the cavity (14) has, in a cutting plane (P) perpendicular to the sliding direction (D) of the piston (15) provided with said piston top (10) relative to the engine cylinder, a section having a contour that is non-circular in shape. An internal combustion engine is also described.
