2.1.3.6. Operation of valves maslorazbryzgivayushchy snuffled

Fig. 2.46. The place of an ustanvka of valves maslorazbryzgivayushchy snuffled: 1 – valve of a maslorazbryzgivayushchy nozzle; 2 – block of cylinders; 3 – bent shaft


Oil pressure, influencing the backpressure ball valve in the valve of a maslorazbryzgivayushchy nozzle, opens and closes the oil channel of a nozzle and operates the beginning and interruption in supply of oil. The oil pressure exceeding a certain value, influencing the backpressure ball valve in the valve of a maslorazbryzgivayushchy nozzle, opens the oil channel of a nozzle, and there is an oil injection. On the contrary, with the oil pressure which is not exceeding a certain value, the backpressure ball valve is blocked by force of a spring and the injection of oil stops.
