    摘要: A fuel injector has an actuator for generating a lifting movement and a lift translator filled with a hydraulic medium and deformable in the lifting direction, for transferring the lifting movement of the actuator to a valve needle, provision being made for a compensating chamber for the hydraulic medium, the compensating chamber being connected to an interior space of the lift translator via a throttle opening and enclosed by an elastic casing. Thus, temperature-related quasistatic deformations of actuator, lift translator, and/or valve needle can be compensated for by an exchange of the hydraulic medium between the interior space of the lift translator and the compensating chamber, while the comparatively fast lifting movements of the actuator are transmitted to the valve needle essentially without damping.

    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: The invention relates to a process for metering fuel with a fuel injector (1), in particular an injector for fuel injection systems of internal combustion engines. The fuel injector has an actuator (14) and a valve closing body (6) which can be activated by the actuator (14) to produce a valve stroke, and the valve closing body cooperates with a valve seat face (5) to form a sealing seat. The valve closing body (6) and/or valve seat face (5) has at least one swirl element (27; 41) to produce a swirling flow. In order to vary the fuel distribution of fuel injected by the fuel injector (1), the valve stroke triggered by the actuator (14) has a variable opening speed, whereby a transition from an at least approximately swirl-free preliminary flow of the injected fuel to a swirling flow of the injected fuel is produced by varying the opening speed.

    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: Conventional devices have a valve needle and a shape memory element which, by the application of a controllable magnetic field, executes a control stroke travel that operates the actuator, and having a coil that excites the magnetic field which is situated in a magnet housing which, at its end face, is bordered with respect to an actuating axis by a front wall in each case, the front walls having a through opening radially within the coil. It is a disadvantage that the magnetic field excited around the coil is conducted unfavorably, so that at most a slight magnetic field develops in the shape memory element. The shape memory element has a magnetic field flowing through it, in the direction of its longitudinal extension, if at all. Since the shape memory element has a high magnetic resistance and is developed to be very long in the axial direction, only a very weak magnetic field can be induced in the shape memory element. In response to the magnetic field that is weak at most, the shape memory element can generate only a very slight lift of the valve needle. In the device according to the present invention, a strong magnetic field is conducted through the shape memory elements, and in this way, a large control stroke travel is achieved. The shape memory element(s) is/are positioned generally only in the through opening(s).
