Title: Johann Siller: Innovator in Metering Valve Technology
Introduction
Johann Siller is a notable inventor based in Puch bei Hallein, Austria. He has made significant contributions to the field of metering valve technology, holding 2 patents that showcase his innovative approach to engineering solutions for internal combustion engines.
Latest Patents
Siller's latest patents include a metering valve assembly and a method for operating a metering valve assembly. This invention features a metering valve designed for the precise metering of an aqueous urea solution, which is essential for the post-treatment of exhaust gases from internal combustion engines. The design allows the liquid to be fed in a specific direction to the metering valve, with a mixing chamber that facilitates the mixing of the liquid with gas in a gas flow. Notably, the metering valve can be evacuated contrary to the feeding direction, enhancing its functionality.
Another significant patent is an apparatus for introducing a reducing agent into the exhaust of an internal combustion engine. This apparatus comprises a reservoir, a delivery unit, and a flow path for the reducing agent. It also includes a ventilation device located at a geodetic high point of the flow path, which allows for the return of a minimal fluid quantity to the reservoir even when in a closed state.
