Fuel injector designed to reduce fuel vaporization

摘要

A fuel injector for a petrol engine has an outer annular body and a core member mounted therein. The core member has a central passage which leads from a fuel inlet to adjacent a plate-like valve member which is biased into contact with a seat ring by a spring. The core member is surrounded by a solenoid winding which when energized causes the valve member to lift from the seat ring to allow fuel flow through an outlet orifice. The fuel is conveyed from the inlet to adjacent the valve member by a tubular member which is mounted in spaced relationship within the passage.
