Estimating the term…
The invention relates to an anti-rotation device of a fuel lance arranged in a bore extending through a cylinder head of a cylinder head from an intake opening until a hole provided for receiving a fuel injector, the lance allowing high-pressure fuel to circulate from an intake opening of the lance until the outlet opening of the lance engaging with the intake opening of the fuel injector, the fuel lance including a nut for being screwed into the intake opening of the bore and a tubular member compressed between the nut and the injector, the lance also including the anti-rotation device. The anti-rotation device is a resilient element which is deformed by rotation of the nut, such as to be blocked between the tubular member and an inner wall of the bore, and thus prevent rotation of the tubular member when the nut is screwed.

An anti-rotation device of a fuel lance, the fuel lance being able to be arranged in a bore which extends through a cylinder head from an intake orifice to a pit which is provided in order to receive a fuel injector, the fuel lance being designed to allow high-pressure fuel to flow from an intake mouth of the fuel lance to an outlet mouth of the fuel lance which cooperates with an intake mouth of the fuel injector, the fuel lance comprising a nut which is designed to be screwed into the intake orifice in the bore, and a tubular member compressed between the nut and the fuel injector, the fuel lance additionally comprising the anti-rotation device, wherein the anti-rotation device is a resilient element which is deformed by rotation of the nut, such as to be blocked between the tubular member and an inner wall of the bore, and thus prevent rotation of the tubular member when the nut is screwed.
A fuel lance to be arranged in a bore which extends through a cylinder head from an intake orifice to a pit which is provided in order receive a fuel injector, the fuel lance comprising:
