Valves of maslorazbryzgivayushchy snuffled are installed in the block of cylinders (in a radical neck). Efficiency of cooling of the piston with the sprayed oil is improved due to optimization of placement of valves which are directed to the bottom of each piston. Valves of a maslorazbryzgivayushchy nozzle are developed so that to keep the optimum pressure of oil in the engine when spraying
(fig. 2.45).
