Electromagnetic Fuel Injection Valve

摘要

An electromagnetic fuel injection valve includes a valve element, a movable element, a magnetic core, and a coil. The movable element includes an inner movable element that faces a radially inner part of the magnetic attractive surface of the magnetic core in a moving direction of the valve element. The inner movable element is biased in a valve closing direction by a first spring. The movable element also includes an outer movable element that faces a radially outer part of the magnetic attractive surface of the magnetic core in the moving direction of the valve element. The outer movable element biased in a valve opening direction by a second spring.

1. An electromagnetic fuel injection valve, comprising:
a valve element; a movable element that is configured to move the valve element; a magnetic core that has a magnetic attractive surface facing the movable element; and a coil that is configured to generate a magnetic flux in the magnetic core, the coil disposed on an outer peripheral side of the magnetic core, wherein the movable element includes:
an inner movable element that faces to a radially inner part of the magnetic attractive surface of the magnetic core in a moving direction of the valve element, the inner movable element biased in a valve closing direction by a first spring; andan outer movable element that faces to a radially outer part of the magnetic attractive surface of the magnetic core in the moving direction of the valve element, the outer movable element biased in a valve opening direction by a second spring.
