摘要： A method of metering fuel with a fuel injector, in particular a fuel injector for fuel injection systems in internal combustion engines is described, having a piezoelectric or magnetostrictive actuator and a valve closing body which is operable by the actuator with a valve lift, cooperating with a valve seat face provided on a valve seat body to form a sealing seat. The valve lift may be adjusted variably as a function of a variable control signal triggering an actuator to produce a variable fuel flow at the sealing seat. To produce afitted curve, the fuel flow of the fuel jet sprayed by the fuel injector is measured as a function of the control signal to produce a fitted curve, and a predetermined fuel flow is set with the control signal by using the fitted curve.

摘要： A fuel injector, in particular a fuel injector for fuel injection systems of internal combustion engines, has a piezoelectric or magnetostrictive actuator, a valve closing element that can be actuated by the actuator and that works together with a valve seat face to form a seal seat, and a temperature compensation device. The temperature compensation device has a housing that is elastically deformable along a direction of actuation of the actuator, and has at least one throttle that connects an interior space of the housing with a fuel inlet of the fuel injector. The cross-section of this throttle is dimensioned such that an entry and exit of fuel into the housing of the temperature compensation device is enabled when there is a temperature-caused change in length of components of the fuel injector.

摘要： A fuel injector, particularly an injector for fuel-injection systems of internal combustion engines, has a piezoelectric or magnetostrictive actuator and a valve-closure member which is operable by the actuator with the aid of a valve needle and which cooperates with a valve-seat surface to form a sealing seat. The actuator, at a first end face, abuts against a supporting member that has at least one cut-out through which at least one segment of an actuating sleeve projects. The actuating sleeve, at a first end, acts upon the valve needle, and at a second end, embraces the actuator at a second end face of the actuator facing away from the first end face of the actuator.

摘要： A fuel injector (1), particularly an injection valve for fuel-injection systems of internal combustion engines, has a piezoelectric or magnetostrictive actuator (16) that is arranged in a valve housing (2) and is sealed off from a fuel by an actuator housing (15), and a valve-closure member (7) which is operable by the actuator (16) with the aid of a valve needle (6) and which cooperates with a valve-seat surface (5) to form a sealing seat. The valve housing (2) and the actuator housing (15) have cut-outs (38, 39) adjoining one another, and the valve housing (2) is joined to the actuator housing (15) in an edge area of the cut-outs (38, 39). In this manner, a feed-through opening (41) is formed which is sealed off from the fuel. The feed-through opening (41) is filled with a filler element (43) by which at least one electrical supply line (37) of the actuator (16) is fixed in position in the feed-through opening (41).

摘要： A fuel injector, in particular an injection valve for fuel injection systems of internal combustion engines, has a piezoelectric actuator or magnetostrictive actuator sealed against a fuel by an actuator seal and it has a valve closing body actuatable by the actuator and working together with a valve seat face to form a tight seat. The actuator seal includes a sealing element on the inlet end and a sealing element on the injection end, both designed to be elastically deformable and frictionally engaged with an actuating sleeve. The actuator acts on valve closing body by way of the actuating sleeve, thus at least partially compensating the forces generated by the fuel pressure and acting on the actuator by way of the actuating sleeve.

摘要： A fuel injection valve, in particular an injection valve for fuel injection systems of internal combustion engines, is made of a piezoelectric or magnetostrictive actuator and a valve closing body that can be set in motion by the actuator via a valve needle and that interacts with a valve seat surface to produce a seat. To compensate for the temperature expansion, at least one damping element made of a solid is present and exhibits an almost static behavior at a high deformation rate and is elastically or plastically deformable at a low deformation rate.
