Nozzle body and fuel injection valve

Nozzle body and fuel injection valve A nozzle body (10) for a fuel injection valve (1) and a fuel injection valve (1) with the nozzle body (10) are specified. The nozzle body (10) comprises an injection channel (20) which has a first section (22) and a second section (24), downstream of the first section (22), the first and second sections (22, 24) having a common interface (26). The cross-sectional area of the first section (22) is monotonically decreasing in the course from a fuel inlet opening (221) of the first section (22) to the common interface (26) and the cross-sectional area of the second section (24) is monotonically increasing in the course from the common interface (26) to a fuel outlet opening (242) of the second section (24). 喷嘴主体及燃料喷射阀。用于燃料喷射阀（1）的喷嘴主体（10）以及带有该喷嘴主体（10）的燃料喷射阀（1）被具体说明。喷嘴主体（10）包括具有第部段（22）和第二部段（24）的喷射通道（20），第二部段（24）在第部段（22）的下游，第和第二部段（22、24）具有共同界面（26）。在从第部段（22）的燃料入口开口（221）至共同界面（26）的路线上，第部段（22）的横截面面积是单调递减的，并且在从共同界面（26）至第二部段（24）的燃料出口开口（242）的路线上，第二部段（24）的横截面面积是单调递增的。
