Fig. 2.36. Design of the mechanism of change of phases of gas distribution: 1 – camshaft asterisk; 2 – case; 3 – rotor; 4 – pin; 5 – consolidation; 6 – cover; 7 – groove

The executive mechanism of change of phases of gas distribution consists of the case integrated with an asterisk of the camshaft, a cover, a rotor integrated with a cam-shaft and a pin which defines the mutual provision of a rotor and the case when the engine is stopped. Besides, the rotor has consolidation which isolates a compartment of an advancing and a compartment of delay of opening or closing of valves. The cover and a rotor of the executive mechanism of change of phases of gas distribution have grooves which are used for the correct combination, at survey of the executive mechanism of change of phases of gas distribution (fig. 2.36).
