| 摘要 |
An electromagnetic fuel injector for a fuel injection system is provided with a solenoid winding which, when fed with electrical operating current, produces a saturated magnetic field in at least part of a magnetic circuit, which field is used to attract a member controlling the valve means of the injector and hence the fuel flow. The valve means may include a plunger having a tip portion of a plastics or rubber-like material to engage the valve seat. Methods of attaching the tip portion to the plunger are also described.
