发明名称 DECOUPLING ELEMENT FOR A FUEL INJECTION DEVICE
摘要 A decoupling element for a fuel injection device has a low-noise construction. The fuel injection device includes at least one fuel injector and one receiving bore in a cylinder head for the fuel injector and the decoupling element between a valve housing of the fuel injector and a wall of the receiving bore. The decoupling element has a nonlinear progressive spring characteristic as a solid-state joint, at least one bearing collar including a valve contact surface, which is designed to be spherical, i.e., convex, extending upward from a flat annular area, the flat annular area being supported on a supporting base, and the inside of the annular area has a smaller inside diameter D than the bearing collar and the supporting base, which is supported on the wall of the receiving bore.
