  • the present invention relates to fuel injection pumps for internal combustion engines in general, and more particularly to improvements in fuel injection pumps of the type wherein the amounts of fuel injected into the lcylinders of the engine are regulated by an electronic control circuit. Still more particularly, the invention relates to electronically controlled fuel injection pumps of the-type wherein a piston or an analogous fuel displacing and distributing member is either adjustable or cooperates with an adjusting member to determine the beginning and/or termination of fuel admission into the cylinders and to thus control the amounts of injected fuel.
  • Automotive vehicles wherein the cylinders of the engine receive metered quantities of fuel from an injection pump whole operation is regulated by an electronic control circuit must be equipped with transducers capable of converting electrical control signals into mechanical signals which are employed to adjust the pump as a function of factors which in fluence theoperation of the engine under a given set of circumstances or as a function of internationally created signals serving to insure that the engine is to operate in a certain way.
