Abstract

1,244,295. 295. I.C. engine cylinder heads; valve seats. DAIMLER-BENZ A.G. Jan.20, 1970 [Jan.24, 1969], No.2752/70. Heading F1B. The inlet seat ring 5 has an annular triangular cross-section projection 7 which surrounds the valve head 8 and projects about 0À5 to 1 mm beyond the head surface 6. The sharp edge 7 prevents liquid fuel from flowing on to the surface 6.
