Abstract

POSTUPAK IZRADE SEDIŠTA VENTILA U USISNOM VODU MOTORA SA UNUTRAŠNJIM SAGOREVANJE, naznačen time, što se: - najpre obradi glodanjem glava (1) motora, čime se napravi kućište (2) za prsten sedišta (3) ventila, načinjen od čeličnog liva ili drugog pogodnog materijala; - zatim se u kućište (2), koje je na taj način dobijeno, postavi sedište (3) ventila izvedeno sa obostranim zakošenjem, čiji unutrašnji prečnik (4) je jednak prečniku usisnog voda na mestu gde je formirano kućište (2);- na kraju se na sedištu (3) ventila formira zakošenje (6) kao ležište za pečurku ventila.PROCEDURE FOR MANUFACTURING VALVE SEATS IN THE INTAKE LINE OF INTERNAL COMBUSTION ENGINES, indicated by the fact that: - first, the engine heads (1) are milled, which creates a housing (2) for the valve seat ring (3), made of cast steel or other suitable material; - then in the housing (2), which was obtained in this way, a seat (3) of the valve made with a bevel on both sides is placed, whose inner diameter (4) is equal to the diameter of the suction line at the place where the housing (2) is formed; - on at the end, a chamfer (6) is formed on the seat (3) of the valve as a seat for the valve mushroom.
