Title: The Innovative Mind of Charles L. Bennett
Introduction
Charles L. Bennett is a notable inventor based in Livermore, California, with a remarkable portfolio of 13 patents. His work primarily focuses on advanced engine technologies that enhance efficiency and performance. Bennett's innovative spirit has led to the development of groundbreaking inventions that push the boundaries of engineering.
Latest Patents
Among his latest patents is the Harmonic Uniflow Engine. This reciprocating-piston uniflow engine features a harmonic oscillator inlet valve that oscillates at a resonant frequency to control the flow of working fluid into the engine. The design includes an inlet valve head and a spring that work together as a harmonic oscillator. This allows the inlet valve head to move from an unbiased equilibrium position to a biased closed position, effectively occluding the inlet. When released, the valve head oscillates past the equilibrium position to a maximum open position before returning to a biased return position, which chokes the flow and produces a pressure drop that causes the valve to close. Additionally, this harmonic oscillator arrangement enables the uniflow engine to operate reversibly as a uniflow compressor.
Another significant invention is the Double-Reed Exhaust Valve Engine. This engine is based on a reciprocating piston design that extracts work from pressurized working fluid. It incorporates a double reed outlet valve that controls the flow of low-pressure working fluid out of the engine. The double reed provides a stronger force resisting closure of the outlet valve compared to the force that opens it. This design allows for engine operation at relatively higher torque and lower efficiency at low speeds, while achieving lower torque but higher efficiency at high speeds.
