Abstract

"VáLVULA DE INJEçãO". A presente invenção apresenta uma válvula de injeção, especialmente para a injeção de combustível, que possui uma câmara da válvula (11) possuido uma abertura de injeção (14) e um canal de admissão de combustível (12), e um módulo de aquecimento disposto na câmara da válvula (11) na sua extremidade afastada da abertura de injeção (14), válvula esta que possui uma caixa de módulo (24) fixada na câmara da válvula (11) e um elemento de aquecimento (32) para aquecer o combustível que atravessa a caixa de módulo (24). Para uma adaptação otimizada, do ponto de vista da mecânica dos fluidos e da termodinâmica, do módulo de aquecimento (23) à geometria da válvula de injeção, na caixa de módulo (24) é formado um tubo de imersão (25) que imerge profundamente no canal de admissão de combustível (12), em cuja extremidade livre no lado da válvula desemboca um canal de aquecimento (31) que atravessa a caixa de módulo (24) axialmente, conduzindo combustível. O elemento de aquecimento (32) é feito em forma de bastão e se estende através de todo o canal de aquecimento (31)."INJECTION VALVE". The present invention provides an injection valve, especially for fuel injection, having a valve chamber (11) having an injection port (14) and a fuel inlet channel (12), and a heating module disposed. in the valve chamber (11) at its distal end from the injection port (14), which valve has a module housing (24) attached to the valve chamber (11) and a heating element (32) to heat the fuel that goes through the module box (24). For optimum adaptation, from the point of view of fluid mechanics and thermodynamics, of the heating module (23) to the geometry of the injection valve, in the module housing (24) a deep immersion tube (25) is formed. at the fuel inlet channel (12), at whose free end at the valve side a heating channel (31) flows through the module housing (24) axially, conducting fuel. The heating element (32) is rod-shaped and extends through the entire heating channel (31).
