Title: Fuel injector for liquefied fuel
Inventor: DAVID E BENNET
IPC: F02M61/14
Filed: 1998-02-09
Abstract: PROBLEM TO BE SOLVED: To provide an injector equipped with a valve which is used for high pressure liquefied fuel, whose shape is comparatively simple and plain, and life to be used is long. SOLUTION: This fuel injector is equipped with a fuel channel 30 which is passed through the main body of the fuel injector and a valve 52 arranged in the fuel channel 30. The valve head of the valve 52 is formed of an elastic material, and deformed against a valve seat so as to seal a fuel outlet. Also, this fuel injector is equipped with a locking member which can be engaged with the valve 52 so that the deformation of the valve head can be restricted. Preferably, the valve 52 is closed by being energized by a spring, and opened by solenoid driving. Also, the valve head has generally a slant bottom wall, and the bottom wall is preferably formed in a manner that it is engaged with the valve seat by its restricted surface area so as to reduce force by which the bottom wall and the valve seat are separated from each other.
