Abstract

Buluş içten yanmalı motorlar için bir enjeksiyon valfı (10) olup özelliği, yüksek basınç bölgesinin (24) sızdırmazlık contası (41) ile yeterli oranda aynı genişliğe sahip olduğu dar bölgesinin (242) en azından bir kısmını yeterli oranda genişletecek şekilde sağlanan ve bahsedilen dar bölgeden (242) başlayıp sızdırmazlık contasına (41) göre daha geniş olan üst bölgeye (243) kadar uzanan en az bir adet kanal (241) içermesidir.The invention is an injection valve (10) for internal combustion engines, characterized in that said high-pressure zone (24) is provided with said narrow zone, which is provided to sufficiently extend at least a portion of the narrow zone (242) in which the sealing gasket (41) is sufficiently the same width as the sealing gasket (41). (242) and extending to the upper region (243) which is wider than the sealing gasket (41).
