Devices for regulating the delivery of fuel from an injection pump to the cylinder of an internal combustion engine

摘要

A device regulates the fuel delivery from a fuel injection pump to the cylinder of an internal combustion engine by means of two secondary chambers connected respectively to the induction manifold and Venturi tube, and a main chamber open to the outside, so that pressure variations in the Venturi tube and manifold cause the diaphragms of the respective chambers to move, thereby acting upon mechanical transmission means to control a regulating component of the injection pump.
