Abstract

INJETOR DE COMBUSTìVEL. A presente invenção refere-se a um injetor de combustível compreendendo: um conduto de suprimento de combustível (1) para transporte de fluido a partir de uma extremidade de base (3) do injetor de combustível para uma extremidade de ponta (5) do injetor; um bocal (7) na extremidade de ponta (5) do injetor para injeção do combustível em uma câmara de combustão; um meio condutor térmico (11, 12) para condução de calor a partir do referido bocal (7) na extremidade de ponta do injetor para a extremidade de base do injetor para resfriamento do bocal; e um alojamento (13) para o referido conduto de suprimento de combustível (1), o referido bocal (7) e o referido meio condutor térmico, o referido meio condutor térmico é termicamente isolado do referido conduto de suprimento de combustível (1) entre as referidas extremidades de ponta (5) e de base (3) do injetor.
