摘要： The invention relates to a nozzle assembly (1) for a fluid injector. The nozzle assembly (1) comprises a nozzle body (2) with a central axis (Z), the nozzle body (2) having a nozzle body recess (21), at least one injection opening (22) and an outer wall (24) facing away from the nozzle body recess. The nozzle assembly (1) further comprises a nozzle tension nut (3) by means of which the nozzle body (2) can be coupled to an injector body (4), the nozzle tension nut (3) having an inner wall (31) facing the outer wall (24) of the nozzle body (2). The nozzle body (2) and the nozzle tension nut (3) are formed such that, under the effect of an operational pressure exerted in ordinary operation by a metered fluid onto the nozzle body recess (21), the outer wall (24) of the nozzle body (2) rests, at least in part, against the inner wall (31) of the nozzle tension nut (3) in the radial direction (200). The invention further relates to a fluid injector with a nozzle assembly (1) and an injector body (4).

摘要翻译： 用于流体注射器的喷嘴组件包括具有中心轴线的喷嘴主体，喷嘴主体具有喷嘴主体凹部，至少一个喷射开口和背离喷嘴主体凹部的外壁。 喷嘴组件还包括用于将喷嘴主体连接到喷射器主体的喷嘴张紧螺母，喷嘴张紧螺母具有面向喷嘴主体的外壁的内壁。 喷嘴体和喷嘴张紧螺母形成为使得在通过计量流体在喷嘴体凹部的普通操作中施加的操作压力的作用下，喷嘴体的外壁至少部分地抵靠 喷嘴张紧螺母的内壁在径向方向。
