摘要

The valve has a valve seat body (16) with a fixed valve seat (29) that is arranged downstreamly with a hosing down unit (23). The hosing down unit is designed as a disc-shaped curve. A groove-shaped annular gap is formed with a lower face side (17) of the valve seat body or a valve seat carrier (1). A fuel plate (26) is hose downable in a desired hosing down angle using the groove-shaped annular gap.
