![]() Cylinder head on internal combustion engine
专利摘要:
A cylinder head for internal combustion engines, especially Diesel engines, with at least one opening for a passage forming an inlet or outlet and leading to a combustion chamber. This opening which is adapted to be closed and opened by a valve is on that side thereof which faces in the direction toward the combustion chamber, provided with a valve seat ring fastened in the opening of the passage. Each valve seat ring is to its major extent conical with the basis of the cone pointing toward the combustion chamber while only that end of the valve seat ring which faces away from the combustion chamber is in a projecting manner fastened to the cylinder head. 公开号:SU776570A3 申请号:SU762418958 申请日:1976-11-11 公开日:1980-10-30 发明作者:Эльсбетт Людвиг;Эльсбетт Гюнтер 申请人:за вители; IPC主号:
专利说明:
It is formed by rolling the ends .17, 18, respectively, from groove 19, 20. The Iissan of the valve seats showed W6, as a rule, it is enough for the thermal power to take place only in the area of the sealing edges 21, 22 of the valves. However, the saddles can be installed so that the heat gap 4 will continue from the combustion chamber 13 to the gauge 19 (Fig. 3). . In addition, the outer conic surface of each saddle can be made in the form of two sections 23 and 24, the section 24 located at the base 14 of the saddle forms an inclination angle less than the inclination angle of the section 23 of the main conical surface 9 (Fig. 4) . When the engine is operating in the area of the overhaul 3, high thermal conditions occur. Kie Stresses that cause: cracking. Saddles, sniping along the slice, allow the danger zone to be shielded. The slope of both surfaces 11, 12, and surfaces 9,10 is selected so that the saddles 5,6 due to thermal and / or mechanical loads are not braked on surfaces 11,12, and can slide along this surface m. : ...--: With the proposed mounting of saddles, each saddle, depending on thermal and / or mechanical loads, can expand and contract within the limits of the chamber. burned and in the transverse direction, due to which stresses in the saddles are eliminated, which can lead to their knocking out or breaking.
