Process for reducing the pressure drop and at the same time dempning or braking of the hydraulic vibrations in a brendstofindsprojtningspumpes working chamber and thus in its hojtryksledning as well as a pump for the, practice of the procedure laid down
Process for reducing the pressure drop and at the same time dempning or braking of the hydraulic vibrations in a brendstofindsprojtningspumpes working chamber and thus in its hojtryksledning as well as a pump for the, practice of the procedure laid down
A means of damping cyclic fuel injection pressure drop in a constant-stroke, variable delivery flow rate injection jerk-pump for an internal combustion engine, consisting in slowing down fuel pressure drop at the end of every injection cycle by increasing the added pressure head losses of fuel backflow by a reduction of the free passageway cross-sections through which the fuel flows successively on its return path from the pump working chamber to the spill port.
