Abstract

A fuel injection system is proposed for internal combustion engines having a plurality of injection valves for supplying fuel to the engine. Each injection valve is connected by a yieldable support bracket with a rigid fuel distributor line. The bracket is mounted pivotally with an annular coller secured to the injection valve. The fuel distributor line is arranged to engage rib-like carrier members connected with the internal combustion engine and is held against the carrier member by yielding clamp elements. After the valves are engaged in the sockets of the fuel distributor line and the bore of the cylinder head, then the support brackets are swung upwardly to tension the seal elements that are disposed in proximity to the opposite ends of the valve. As a result, not only a more secure connection between the fuel distributor line and the injection valves is obtained, but also rapid assembly or disassembly of the fuel injection system.
