Common rail fuel distribution for fuel injectors, at an IC motor, has pressure bodies held to the distribution tube by screw bolts giving a sealed fit for the branch tubes leading to the injectors

摘要

The common rail for a fuel feed to injection valves, at an internal combustion motor, has a distribution tube (1) to take the fuel under pressure with branch drillings leading to the injectors at the motor cylinders. The branch tubes (3) are secured at the sealed seats of the drillings by a pressure body (12) formed by straps (14) mounted at the distribution tube. The body has a passage opening for the branch tube at the pressure surface. The strap is secured by at least one screw bolt (15), offset from the branch drilling.
