Title: The Innovative Contributions of John R Jefferson
Introduction
John R Jefferson is a notable inventor based in Rainham, GB, recognized for his significant contributions to fuel injection technology. With a total of six patents to his name, Jefferson has made advancements that enhance the efficiency and performance of fuel injection systems.
Latest Patents
One of Jefferson's latest patents is a fuel injection pump designed with angularly adjustable stop rings. These stop rings limit the outward movement of the pumping plungers, allowing for precise control over the maximum fuel output of the pump. The innovative design features an outwardly extending curved stop surface, enabling adjustments to the maximum fuel output by altering the angular setting of the rings. As engine speed increases, the plungers follow paths determined by the surface, resulting in a decrease in the maximum fuel delivery of the pump.
Another significant patent is a liquid fuel injection pumping apparatus. This apparatus includes a plunger that moves inwardly in a bore to deliver fuel through the action of a roller and a cam. An adjustable stop ring limits the outward movement of the plunger, thereby controlling the maximum fuel supplied to the engine. The ring is positioned by a piston that is acted upon by liquid under pressure, which is supplied by a low-pressure pump. The pressure downstream of the restrictor is managed by a valve that includes a spring-biased valve member, ensuring optimal performance.
