Beschreibung
Zusammenfassung:	The utility model discloses a composite sealing structure for a lute-shaped joint of a low-pressure fuel pipe of an engine, which comprises a part, a second composite sealing gasket, a lute-shaped joint, a first composite sealing gasket and a hollow bolt are sequentially arranged above the part, and the hollow bolt sequentially penetrates through the first composite sealing gasket and the lute-shaped joint. According to the composite sealing structure for the engine low-pressure fuel pipe lute-shaped connector, the hollow bolt penetrates through the first composite sealing gasket, the lute-shaped connector and the second composite sealing gasket to be installed on a part so as to achieve the functions of being communicated with a fuel oil way and guaranteeing oil way sealing, the rubber sealing high point is moved outwards through the second composite sealing gasket, and the sealing effect is good. Even in a limit state, a rubber sealing high point can still be pressed by the lute-shaped connector and a plane
