PRESSURE REGULATOR FOR INJECTION SYSTEMS FOR INTERNAL COMBUSTION ENGINES

摘要

The pressure regulator keeping a constant difference between the fuel pressure supplied to the injectors and the fuel pressure in the intake manifold of an internal combustion engine, comprises a pressure sensitive diaphragm associated with closure means of the inlet opening of a fuel returning pipe to the vehicle tank. Spherical joint means are disposed between said closure means and said inlet opening in order to maintain a parallel relationship between them.
