ABSTRACT:
The invention relates to a fuel oil supply assembly of the type having a magnetic pump and an armature for driving a pump element or piston which is a part of a resilient oscillatory system. A flow restricting pressure regulating vlave in the delivery line is itself regulated in a manner such that the stroke of the oscillatory system is automatically adjusted so that only the exact quantity of oil required by the nozzle is delivered. The intermittent delivery movement inherent in the oscillatory system is thus made smoother by a damping of the oscillations which results from the piston being caused to travel over only a fraction of its maximum stroke.
