Title: Innovations of Charles R. Kelso
Introduction
Charles R. Kelso is a notable inventor based in Canton, MI (US), recognized for his contributions to fuel injection technology. He holds two patents that showcase his innovative approach to enhancing fuel injector systems.
Latest Patents
Kelso's latest patents include the "Force Balanced Electronically Controlled Fuel Injector." This invention features a unit fuel injector that comprises an injector body containing a pumping chamber. The pumping chamber receives fuel at a low pressure level from a fuel supply passage for subsequent discharge at a high pressure level. The design includes a discharge orifice and a transfer passage that communicates with the pumping chamber and the discharge orifice. A valve element is provided for movement between an advanced position, where the supply passage communicates with the pumping chamber through the transfer passage, and a retracted position, where communication is blocked to allow fuel to flow from the pumping chamber through the transfer passage and out the discharge orifice. The valve element integrates a control valve with a tip valve and a force balancing element that reduces the force biasing the valve element toward its closed position when the pressure within the pumping chamber increases.
