The executive mechanism of change of phases of a gazoraspredeleniye consists of the case incorporated with an asterisk of a camshaft, a cover, a rotor incorporated 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 a gazoraspredeleniye have grooves which are used for the correct combination, at survey of the executive mechanism of change of phases of a gazoraspredeleniye
(fig. 2.36).
