Latest Patents

One of Schnedt's latest patents is a device for injecting fuel into the combustion chamber of an internal combustion engine. This innovative device comprises at least one injector, which includes an injector body, a high-pressure accumulator integrated into the injector body, an injection nozzle, a high-pressure bore, and a feed bore. The injection nozzle defines a nozzle chamber and features a nozzle needle that is axially movable, surrounded by the nozzle chamber. The high-pressure bore connects the high-pressure accumulator and the nozzle chamber, while the feed bore is designed to supply high-pressure fuel to the high-pressure accumulator. Notably, the feed bore has a lance connection positioned laterally on the injector body, formed as a separate bore from the high-pressure bore, directly connecting the lance connection to the high-pressure accumulator.

Another significant patent by Schnedt is a fuel supply system for heavy oil common-rail injection systems. This system is designed for internal combustion engines and includes a tank, a primary feed pump for delivering heavy oil from the tank to a high-pressure pump, and a high-pressure accumulator feeding at least one injector. Additionally, it features a purge valve connected to the high-pressure accumulator via a separate high-pressure line, allowing a portion of the heavy oil to be directed back into the tank. The purge valve includes a movable valve member, a high-pressure connection, a low-pressure connection, and actuating means for the valve member, with the valve seat designed as a sliding seat.
