Latest Patents

Bruce E. Varney holds several notable patents, with his latest innovations focusing on advanced fuel injector assemblies.

1. **Pinned Injector Assembly**: This patent describes a unit fuel injector that features a unique threadless injector body attaching device. This device connects the upper and lower sections of the injector without imparting transverse load, which minimizes bore distortion, plunger wear, and the risk of failure. The design incorporates a groove in the upper body section and corresponding apertures in the lower body section, allowing for a slip-fit connection through pins. This innovative approach ensures a secure yet flexible assembly that optimizes the sealing load for effective fluid containment.

2. **Fuel Injector with Isolated Spring Chamber**: In this patent, Varney presents a refined unit fuel injector that delivers precise control over fuel injection timing. The injector includes a timing plunger situated between upper and lower plungers, along with a spring chamber designed to isolate the timing plunger from pressure variations in the drain system. By preventing outside influences from affecting the timing operations, the injector achieves better performance and reliability. The introduction of a scavenge circuit further enhances the system by directing fuel flow directly to the low-pressure drain without interference.
