Druckübersetzer für ein Kraftstoffeinspritzsystem für Brennkraftmaschinen mit hydraulisch unterstützter Wiederbefüllung

摘要

The invention relates to an injection system for internal combustion engines having a pressure transmitter. The stepped piston (5) of the pressure transmitter is moved backwards into the original position thereof by means of a pressure wave. The second pressure chamber (3) or the injection nozzle (21) is simultaneously refilled from the leak-oil return (39).
