Title:
FUEL INJECTION NOZZLE FOR SUPPLYING FUEL TO INTERNAL COMBUSTION ENGINE
Document Type and Number:
Japanese Patent JPS5825568
Kind Code:
A
Abstract:
The nozzle bore defines a seating 17 adjacent the outlet 15 and the valve member 18 has a shaped portion 22 which extends from a conical portion 21 through the outlet. The shaped portion 22 defines a clearance with the outlet 15 and the conical portion 21 at or adjacent its end nearer to the outlet defines a seating edge for engagement with the seating 17. The increase in the area of the valve member which is exposed to fuel pressure, which occurs as the valve member is lifted from the seating is minimised as compared with known constructions in which the seating edge is disposed at the end of the conical portion remote from the outlet.
