组分输送喷嘴
摘要：
组分输送喷嘴，包括：壳体(11、12)，所述壳体具有组分入口(13)和组分出口(15)；活塞形的闭锁体(20)，所述闭锁体在壳体中滑动支承并且可轴向来回运动，其中，在第一位置中组分出口通过闭锁体的前端部(22)闭锁并且在第二位置中组分出口被释放或打开。组分输送喷嘴具有膜片密封件(30)，所述膜片密封件紧固在闭锁体的后端部上并且紧固在壳体上，从而闭锁体完全处于膜片密封件的一侧上，其中，壳体和/或闭锁体这样构成，使得组分到达闭锁体的所有面上并且因此组分压力处于膜片的完整的作用面上。
摘要（英）：

A component feed nozzle includes a housing, which has a component inlet and a component outlet, a piston-shaped closing body, which is slidably supported in the housing and which can be moved back and forth axially. The component outlet is closed by the front end of the closing body in a first position and the component outlet is released or opened in a second position. The component feed nozzle has a membrane seal, which is fastened to the rear end of the closing body and to the housing in such a way that the closing body is completely on one face of the membrane seal. The housing and/or the closing body are designed in such a way that the component reaches all surfaces of the closing body and thus the component pressure is applied to the complete effective surface of the membrane.
