FUEL INJECTION VALVE

WIPO Patent Application WO/2018/066327

A1

The objective of the present invention is to achieve an inward-opening valve structure with a simple configuration in a fuel injection valve equipped with a drive element that extends in response to applied voltage. Therefore, this fuel injection valve is equipped with: a valve body 1 having an upstream seat part 1a arranged on the upstream side in the axial direction and a downstream seat part 1b arranged on the downstream side in the axial direction; an upstream valve seat 7a that closes an upstream fuel passage when contacted by the upstream seat part 1a; a downstream valve seat 2c that closes a downstream fuel passage when contacted by the downstream seat part 1b; a biasing member 4 that biases the valve body 1 in the direction in which the upstream seat part 1a contacts the upstream valve seat 7a; and a drive element 11 that drives the valve body 1 in the direction in which the downstream seat part 1b contacts the downstream valve seat 2c. When the upstream seat part 1a is separated from the upstream valve seat 7a and the downstream seat part 1b is separated from the downstream valve seat 2c, the valve body 1 is driven by the drive element 11 and injects fuel.
