Latest Patents

Among his latest patents are two remarkable inventions:

1. **High Pressure Fuel Injector with Fuel Drainage Valve**: This invention improves high-pressure fuel injectors for internal combustion engines by addressing issues such as hysteresis delays and fuel leakage during the metering process. It enables precise control of fuel supply pressure through a mechanism that allows the metering and injection plunger to be influenced solely by the incoming fuel pressure. An improved spring arrangement for the plunger incorporates valving that prevents leakage through drain passages during critical phases of fuel metering and injection. Additionally, a double check valve arrangement minimizes back-flow leakage, thereby enhancing the injector's reliability.

2. **Viscosity Responsive Pressure Regulator and Timing Control Tappet System**: This innovative system features viscosity-sensitive mechanisms that generate a simulated fluid pressure correlating to the actual fluid pressure in a specific area of the fluid flow circuit. It includes a pressure regulation system that adjusts to maintain a designated pressure, particularly suited for controlling fuel injector timing using oil supplied by a pump to an engine lubrication circuit.
