Title:
FUEL INJECTION VALVE
Document Type and Number:
Japanese Patent JP2011069264
Kind Code:
A
Abstract:
To provide a fuel injection valve inhibiting a spring from deforming to cause change or deterioration in the fuel injection quantity characteristics.
The fuel injection valve 201 includes the spring 212 generating force for biasing a valve element 208 to the conical face 211A of a valve seat and has a structure in which a movable element 203 and the rod-shaped valve element 208 contacting with one end of the spring 212 and a rotary plate 215 contacting with the other end can rotate in a circumferential direction. With this, generated torsional torque is canceled and there is no case where a flow passage resistance varies, leading to a change in the fuel injection quantity characteristics.
