2.1.1.19. The valve, a klapanny spring, the maslootrazhatelny cap, the directing plug of the valve
Fig. 2.27. Valve components: 1–valve cracker; 2–top plate of a spring of the valve; 3–klapanny spring; 4–maslootrazhatelny kopachok; 5–the directing plug of the valve; 6–valve

Valves are made of heat resisting steel. Each cylinder has two inlet and two final valves. Inlet and final valves have the nitridden surfaces for increase in resistance an istiraniya. The Klapanny spring – variable external diameter. characteristics of a spring are improved at the expense of reduction of the size of the top saddle. The directing plug of the valve is made of the alloyed alloy for increase in resistance to an istiraniye. The saddle of the valve is incorporated with the bottom saddle of a klapanny spring to simplify knot and to improve its maintainability (fig. 2.27).
