Title:
FUEL INJECTION VALVE
Document Type and Number:
Japanese Patent JP2016050557
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a fuel injection valve which controls an amount of a fuel injected from a plurality of injection holes with high accuracy.SOLUTION: A fuel injection valve 1 includes an inner needle 40 for opening/closing a center injection hole 28 and an outer needle 50 for opening/closing an outside injection hole 29 formed radially outside of the center injection hole 28. A housing 20 includes a partitioning member 60 for partitioning the inside of the housing 20 into a first compartment in which the inner needle 40 is accommodated so as to reciprocate and a second compartment in which the outer needle 50 is accommodated so as to reciprocate. An outer wall 612 of one end part 611 for configuring the partitioning member 60 comes into contact with a seal surface 270 of an injection nozzle 27 formed between an edge part 282 for forming an inside opening 281 of the center injection hole 28 and an edge part 292 for forming an inside opening 291 of the outside injection hole 29. Thereby, when a fuel is injected only from the center injection hole 28, the fuel of an inner sack 280 can be prevented from leaking to an outer sack 290.SELECTED DRAWING: Figure 2
