Abstract
A fuel injection nozzle has a valve member which is axially movable within a bore in a nozzle body. It is resiliently urged into contact with a seating at one end of the bore and carries an extension which projects with clearance through an opening at said one end of the bore. Intermediate the ends of the bore is an enlargement to which fuel under pressure can be supplied and the portions of the bore between the enlargement and the other end of the bore tapers inwardly from the enlargement to allow the extension to partake of sideways movement within the opening to minimize the risk of carbon deposit forming in the opening and on the extension.
