摘要： A fuel injector for the direct injection of fuel into the combustion chamber of an internal combustion engine includes a valve needle situated in a nozzle body, the valve needle being actuable by an actuator and acted upon by a restoring spring in such a manner that a valve-closure member which is in operative connection to the valve needle and faces the combustion chamber is kept in sealing contact with a valve-seat surface in the non-actuated state of the actuator. A first jet-opening angle α1 is assigned to a first lift state of the valve needle and a second jet-opening angle α2 to a second lift state of the valve needle.

摘要： A fuel injector, e.g., an injector for fuel injection devices in internal combustion engines, has a valve needle with a valve-closure member which cooperates with a valve seat surface in a valve seat body to form a sealing seat, in which the valve seat body has a plurality of injection orifices that are isolated from the fuel supply by sealing seat. The valve-closure member has a pressure element in a recess facing the valve seat body, which is pre-tensioned against the valve seat body by a spring which is supported on the valve-closure member and presses a disc spring against the valve seat body, in such manner that the disc spring covers at least one of the injection orifices, and the spring element uncovers this injection orifice when the tension exerted by the pressure element is removed.

摘要： A fuel injector for the direct injection of fuel into the combustion chamber of an internal combustion engine encompasses a piezoelectric or magnetostrictive actuator, a valve needle actuable by the actuator, the valve needle cooperating with a valve-closure member to form a sealing seat together with a valve-seat member, and a restoring spring by which the valve needle is acted on in a closing direction. The valve needle is pressure-equalized in that the force exerted by the fuel pressure on the valve needle in the opening direction is approximately equal to the force exerted by the fuel pressure on the valve needle in the closing direction.

摘要： A fuel injector, in particular, an injector for fuel injection systems of internal combustion engines, having an actuator, which cooperates with a valve needle, has a first valve closure member that is arranged on the valve needle, the valve closure member cooperating with a first valve seat surface on a valve body forming a first sealing seat. A second valve closure member cooperates with a second valve seat surface in the valve seat body forming a second sealing seat. The valve needle, or the first valve closure member, has a limit stop, against which, after a partial stroke of the valve needle, a counter limit stop of the second valve closure member strikes, lifting the second valve closure member from the second sealing seat in response to a further stroke of the valve needle.

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.
