Title:
FUEL INJECTION VALVE
Document Type and Number:
Japanese Patent JP2014148956
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a fuel injection valve for turning an upstream of a seat part and reducing spray penetration.SOLUTION: When flows into injection hole inlets are designated as arrows 101a-106a and injection outlet directions are designated as arrows 201-206, an angle α formed by an inflow direction 101a and an outlet direction 201 of an injection hole 71 can be made large. A method for providing a torsion angle α is set so that a side groove 15a is twisted on an outer peripheral side 15a of a guide member 12a relative to an axial line O1. Furthermore, a flow passage area of the side groove 15a is set smaller than a flow passage area on an upstream of the guide member 12a, and larger than a flow passage area of a seat part 7B constituted by a gap between a valve body 7 and an orifice cup 7.
