ABSTRACT:
A fuel metering device for internal combustion engines is simple in structure, efficient in operation and capable of recirculating unused fuel. The device primarily comprises a plurality of passage elements interconnected to form the configuration of an inverted isosceles triangle having a median. The lower vertex of the triangle is connected to a fuel nozzle adjacent a venturi in an air supply passage of the engine, fuel is supplied under pressure from a pump to one upper corner of the triangle, and unused fuel is recirculated from the other upper corner to the fuel pump. The device operates in a manner equivalent to an electrical wheatstone bridge such that the fuel flow in the device tends to produce a balanced condition.
