    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.

    摘要: The invention relates to a hydraulically actuated cutoff valve which is provided as an intake valve for switching between a master cylinder and an intake side of a feed pump of a slip-controlled vehicle brake system. The invention sets forth that the cutoff valve is embodied with a valve closing body that has a valve tappet which passes through an annular actuating element and is in engagement with a rocker element embodied as a cup spring, which rests on an annular pivot bearing. If the actuating element is acted upon by pressure, it presses down an outer edge of the rocker element, and as a result a middle of the actuating element executes a pivoting motion in the opposite direction that closes the cutoff valve. The invention has the advantage of an economical cutoff valve that has only a small number of components, and the invention can be used in a hydraulic vehicle brake system.

    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 for fuel injection systems of internal combustion engines has a valve-closure member that is in working engagement with a valve needle and that coacts with a valve-seat surface positioned in an orifice of a valve-seat member to form a sealing seat. The fuel injector has at least one spray discharge opening positioned in the valve-seat member. Between the valve-seat surface and the spray discharge opening, a second surface that make a more acute angle with the center axis of the fuel injector than the valve-seat surface, is formed by the orifice of the valve-seat member. A closure element extension whose enveloping surface forms an obtuse angle with the contiguous contour of the valve-closure member is positioned at the downstream end of the valve-closure member.

    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.
