2.1.2.2. Design of the mechanism of change of phases of gas distribution

Fig. 2.31. Constructive scheme of operation of the mechanism of phases of gas distribution: 1 – sensor of position of the crankshaft; 2 – sensor of provision of a cam-shaft; 3 – PCM block; 4 – the oil operating valve (OCV); 5 – executive mechanism of change of phases of gas distribution; 6 – electric signal; 7 – hydraulic pressure


The mechanism of change of phases of gas distribution consists of the executive mechanism, the oil operating valve (OCV), the sensor of position of the crankshaft, the sensor of provision of a cam-shaft and the PCM block (fig. 2.31, 2.32 and tab. 2.12).

Fig. 2.32. Flowchart of system of hydraulic pressure: 1 – oil pallet; 2 – oil pump; 3 – oil pipeline; 4 – oil filter; 5 – the oil operating valve (OCV); 6 – adapter of the oil managing director of the valve (OCV); 7 – cam-shaft; 8 – executive mechanism of change of phases of gas distribution; 9 – block of cylinders
