Abstract
Beim Einsatz von Einspritzdüsen insbesondere für Kraftmaschinen muss ein vorhandenes Spiel kompensiert werden. Die Kompensation des Spieles kann dabei dadurch erzeugt werden, dass ein geschlossenes hydraulisches System erzeugt wird und über einem Kolben (14) ein oberes Arbeitsvolumen (V1) und unter dem Kolben (14) ein unteres Arbeitsvolumen (V2) geschaffen wird. Ein etwa auftretender Druckunterschied zwischen dem oberen und unteren Arbeitsvolumen (V1, V2) wird durch einen Fügespalt (32) dann ausgeglichen, wenn sich der Druckunterschied langsam aufbaut.When using injectors, in particular for engines, an existing clearance must be compensated. The compensation of the game can thereby be generated in that a closed hydraulic system is generated and above a piston (14) an upper working volume (V1) and below the piston (14) a lower working volume (V2) is created. An approximately occurring pressure difference between the upper and lower working volume (V1, V2) is compensated by a joint gap (32), when the pressure difference builds up slowly.
