Abstract

Ein Brennstoffeinspritzventil (1), insbesondere ein Brennstoffeinspritzventil (1) für Brennstoffeinspritzanlagen von Brennkraftmaschinen, umfaßt einen piezoelektrischen oder magnetostriktiven Aktor (2), der über einen hydraulischen Koppler (10) einen Ventilschließkörper (17) betätigt, der mit einer Ventilsitzfläche (18) zu einem Dichtsitz zusammenwirkt. Der hydraulische Koppler (10) weist einen Geberkolben (11) und einen Nehmerkolben (12) auf, die durch einen Kopplerspalt (13) voneinander beabstandet sind. Der hydraulische Koppler (10) definiert mit einer Membran (35), welche mit dem Geberkolben (11) verbunden ist, und einer Dichtung (36), die mit dem Nehmerkolben (12) verbunden ist, ein Kopplervolumen (34) und ein Ausgleichsvolumen (31), welche mit einem Kopplermedium gefüllt sind.
