摘要

The valve has a valve locking body that interacts with a valve seat face and a seal seat. A sprayer opening is provided in a valve seat body. A turbulence body, arranged downstream of the valve seat, has upper surface traversed by number of channels which are separated by bars (40). Discontinuous walls (41) split up the channels into sub-channels which taper itself in the direction of spraying, where bars and walls are of same height.
