摘要： An injection nozzle for an internal combustion engine has a valve member (10) with a seating line (112) defining a seat diameter, the seating line (112) being engageable with a seating surface (14) to control fuel injection by the nozzle, in use. The seating line is defined by an annular ridge (40, 44, 46), integrally formed with the valve needle (10), so as to reduce variations in the seat diameter which would otherwise arise at manufacture due to contact between the valve needle (10) and the seating surface (14) in regions other than at the seating line. The invention provides an advantage in manufacture as repeatability and consistency of the geometry, and in particular the effective seat diameter, of nozzle products is improved.

摘要： A fuel injection nozzle of the outwardly opening type has a valve member movable outwardly by the fuel pressure within a bore in a nozzle body. The member is biased to the closed position by an elastic member in the form of a rod. At its end remote from the valve head, the rod engages a collar between which and an adjacent part of the valve body is a shim. The thickness of the shim is selected so that the tension force in the rod is higher than is required to give the desired nozzle opening pressure and this is adjusted to the desired value by compressing a portion of the nozzle body using a cap nut which secures the nozzle body to a supporting part.
