Latest Patents

Amlung holds a patent for a "Unit injector with hard stop timing plunger." This invention features an improved cam-operated, open nozzle, unit injector that includes a unique injector body formed by a barrel, spring housing, and nozzle. The design incorporates a central bore for receiving a variable length plunger assembly, which is mounted for reciprocal movement within the injector body. The variable length plunger consists of an outer plunger and an inner plunger, combined with a timing plunger that creates a collapsible timing chamber. This chamber allows for the metering and expulsion of a variable quantity of fuel on a cycle-by-cycle basis, providing controlled variation in injection timing based on the timing fluid supplied to the injector. The timing plunger is equipped with a radial flange that engages a stop in the injector barrel, ensuring precise location during the metering process and making the injector timing insensitive to unpredictable pressure variations. Additionally, the injector may include a damping chamber to prevent damaging engagement between the timing plunger and the injector barrel.
