2.1.1.15. Camshaft asterisk

Fig. 2.23. Camshaft asterisk: 1–camshaft asterisk; 2–executive mechanism of change of phases of a gazoraspredeleniye


In a design the camshaft asterisk from the alloyed alloy of the high rigidity, tempered for increase of resistance to an istiraniye in a point of contact to a chain of a drive of the mechanism of a gazoraspredeleniye is used. On engines of the L3 models the asterisk of a camshaft of inlet valves is incorporated with the executive mechanism of system of change of phases of a gazoraspredeleniye (fig. 2.23).
