Abstract

Liquid fuel injector for internal combustion engines, to deliver to the combustion chamber of an associated engine driven loads of liquid fuel received from a high pressure fuel source, comprising a tubular body provided with an orifice or core provided with a valve seat and a discharge tip at one end; a pressure-actuated internal opening valve arranged in said orifice or core; means for pushing said valve towards the valve seat; an open valve guide closing the end of the orifice or web farthest from the valve seat, said valve having a contact or friction portion located in the opening of the valve guide to mount such valve in its alternate approach movement and moving away from the valve seat; and means that provide a passage for the fuel flow around the periphery of the contact or friction portion between the ends of said guide.
