摘要

The valve has a multi-hole nozzle (1) with four spraying hole channels (51-54) that are located on one of two central longitudinal axes and are oppositely arranged in pairs. Two points (S1, S2) of the central longitudinal axes are formed on a common circle line (K). A diameter (Dk) of the circle common line is smaller than a diameter of a valve seat surface of a nozzle body (2).
