Title: The Innovations of Ernst L. Ranft
Introduction
Ernst L. Ranft is a notable inventor based in Sudbury, MA (US), recognized for his contributions to automotive technology. He holds 2 patents that showcase his innovative approach to enhancing engine performance and efficiency.
Latest Patents
One of his latest patents is the "Air Diverter Valve." This invention is designed for systems that deliver air from an air pump to the exhaust system of an internal combustion engine. The air diverter valve assembly features a regulating control that responds to air pump discharge pressure. This mechanism positions the diverter valve member to divert excess air flow away from the exhaust system when the pressure exceeds a selected value. Additionally, the assembly includes a timed anti-backfire provision that overrides the regulating control, diverting all air flow to the atmosphere upon a sudden decrease in induction manifold pressure.
Another significant patent is the "Air Flow Control Unit for Engine Secondary Air Supply." This invention is also aimed at delivering air from an air pump to an exhaust system and accessories for an internal combustion engine. The air flow control unit comprises a high-pressure relief valve, an outlet open to the exhaust system, a vent open to the atmosphere, and an outlet open to the accessories with a check valve. The valve member is movable in response to an engine signal, allowing it to switch between positions that control the exhaust system outlet and the vent. A low-pressure relief valve is included in the vent to maintain a minimum low pressure in the unit when the valve member is in its first position.
