1. 8004789-7 2 med en tvärsektionsprofil i form av bokstaven U, i vilken år inpres- sad den av ett formbart plastmaterial utförda packningsringen. En nackdel med denna ring är likaså att den är komplicerad. Föreliggande uppfinning avser nu att wliminera de ovannämnda nackdelarna hos en cylinderlockspackning och detta uppnås enligt uppfinningen i huvudsak därigenom att den övre och under sidan av den av stål utförda packningsringen är utformad konvext rundad eller välvd med en krökningsradie, som uppgår till mellan 6 och 30 gånger ringens bredd. Tack vare denna konvexa vålvning av den övre och undre sidan av tätningsríngen möjliggöres en viss svängningsrörelse hos cylinder- locket vid deformationer av cylinderlocksväggen utan att några stör- ningar'uppträder. Uppfinningen beskrives närmare nedan under hänvisning till bi- fogade ritning, som visar en schematisk sektion genom en packnings- ring enligt uppfinningen. I ett cylinderfoder 1 är utformat ett ringspår 2, mot vars botten vilar en med radiellt spel anordnad packningsring 5 av stål och med en höjd v. Översidan Ä och undersidan 5 av denna packnings- ring 3 är konvext avrundad eller välvd med en krökningsradie R, som uppgår till mellan 6 och 30 gånger ringens 5 bredd s". I den mot- satta väggen av cylinderlocket 7 är likaså utformat ett ringspår 8, som motsvarar ringspåret 2 i cylinderfodret 1. Cylinderlocket 1 anligger med botten av ringspâret 8 mot packningsringen 3. Cylinderlockspackningen enligt uppfinningen lämpar sig för förbränningsmotorer och särskilt för dieselmotorer med en hög grad av överladdning. 7 Patentkrav Cylinderlockspackning för förbränningsmotorer och bildad av en packningsring, som dels med spelrum är insatt i ett i den övre ändytan av ett cylinderfoder utformat ringspår och dels är insatt i ett i cylinderlonknts mot cylindern vända sida beläget ringspår, k ä n n e t e c k n a d av att den övre (N) och undre (5) sidan av den av stål utförda packningsringen (3) är utformad konvext rundad eller välvd med en krökningsradie (R), som uppgår till mellan 6 och 50 gånger ringens (5) bredd (s").8004789-7 2 with a cross-sectional profile in the form of the letter U, in which year the packing ring made of a moldable plastic material was pressed. A disadvantage of this ring is also that it is complicated. The present invention now intends to eliminate the above-mentioned disadvantages of a cylinder head gasket and this is achieved according to the invention mainly in that the upper and below the side of the gasket ring made of steel is formed convexly rounded or arched with a radius of curvature amounting to between 6 and 30 times the width of the ring. Thanks to this convex curvature of the upper and lower side of the sealing ring, a certain pivoting movement of the cylinder head is made possible in the event of deformations of the cylinder head wall without any disturbances occurring. The invention is described in more detail below with reference to the accompanying drawing, which shows a schematic section through a packing ring according to the invention. In a cylinder liner 1 an annular groove 2 is formed, against the bottom of which rests a packing ring 5 of steel arranged with radial play and with a height v. The upper side Ä and the lower side 5 of this packing ring 3 are convexly rounded or curved with a radius of curvature R In the opposite wall of the cylinder cover 7 a ring groove 8 is also formed, which corresponds to the ring groove 2 in the cylinder liner 1. The cylinder lid 1 abuts with the bottom of the ring groove 8 against the packing ring 3. The cylinder head gasket according to the invention is suitable for internal combustion engines and in particular for diesel engines with a high degree of supercharging. in an annular groove located in the side of the cylinder facing the cylinder, characterized in that the upper (N) and lower (5) side of the steel packing ring (3) is convexly rounded or arched with a radius of curvature (R), which amounts to between 6 and 50 times the width (s ") of the ring (5).
