Fuel-Injection Pumps TRIZ Cases

Modified roll-angle tooth profiles keep governor and pump input speed consistent, stabilizing aircraft generator frequency.

Parallel pressure relief valves with distinct opening thresholds regulate pump output, reducing wear on the primary valve and minimizing pressure pulsations.

A fuel injector needle control system uses four distinct orifices to manage fluid pressure pathways for precise injection timing.

Segmented vent lines with a collection chamber remove air from the speed-dependent pressure line, preventing advance piston damage.
