Abstract

Improvements in the construction of fuel injectors for internal combustion engines, injectors comprising a tubular body provided with a valve chamber, a valve guide in which a pressure actuated valve is mounted and housed in the aforementioned chamber and a spring that propels the valve towards a seat or stop provided with a discharge orifice, characterized in that the valve guide is made up of a generally cylindrical sleeve provided with a threaded and stepped external surface and the end of the tubular body most accommodated in the seat or valve stop appears provided with a threaded and stepped surface coincident with that to form an annular groove between the two, in such annular groove a solidifying and initially fluid sealing product is arranged that is compressed when the guide sleeve is coupled to the injector to fill said throat and force the sealant to penetrate through the steps of threaded or threaded in both directions from the aforementioned throat, the threaded or threaded passages of the stepped surfaces of the valve guide and of the tubular body being formed in the same turn, although provided with different weight diameters.
