Abstract
A fuel distributor, including a plug connection which serves to provide electrical contact for the fuel injection valves comprising a socket and a plug. The plug connection that is located directly on the valve connection neck, in a region between two sealing elements, that seal off a connection between the fuel distributor and the fuel injection valve, so that the fuel-carrying region is sealed off from the guide conduit, which in turn is sealed off from external influences such as splashing water. Thus, even the plug connections located in the region of the guide conduit are protected. The fuel distributor is especially suitable for fuel injection systems of mixture-compressing internal combustion engines with externally supplied ignition.
Claims5
A fuel distributor for fuel injection systems of mixture-compressing internal combustion engines with externally supplied ignition, for supplying fuel to at least two fuel injection valves, having a fuel conduit and a guide conduit parallel to said fuel conduit for receiving electrical lines;
- a number of valve connection necks corresponding to the number of fuel injection valves, the fuel injection valves include connection tangs which extend parallel to the longitudinal valve axis of the fuel injection valves which can be inserted into said valve connection means;
- and an electrical plug connection that comprises a plug (24), the connection tang (21) is cup-shaped and has an annular wall (20) extending concentrically with the longitudinal valve axis (15), said wall at least partly fits into an annular chamber (14) formed by an inner branch (10) and an outer branch (11) of the valve connection neck (4) of the fuel distributor (1).
