Latest Patents

Francis R Draper holds a patent for a fuel pumping apparatus designed to supply fuel to an engine. This apparatus features a pumping plunger that is reciprocable in a cylinder by a cam with cam lobes. During the forward rotation of the engine, fuel is displaced by the leading flanks of the lobes as the plunger moves inward. A key feature of this invention is an electrically controlled valve that allows fuel flow through an outlet to the engine. The control system receives plunger position signals, which are arranged to occur substantially halfway along the trailing flanks of the lobes. This design ensures that if the engine rotates in reverse, the valve remains open while the plunger is moved inwardly.
