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, 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： 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).

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 among others to a method for producing outlet openings (32) in a valve, in particular a fuel injection valve. The injection valve has a fuel inlet (2), an excitable actuating device (1, 2, 19) by which a valve closing member (28) is movable, a fixed valve seat (27) embodied on a valve seat element (26), with which seat the valve closing member (28) cooperates to open and close the valve, and at least one outlet opening (32), as a fuel outlet, provided downstream of the valve seat (27). The at least one outlet opening 32 is produced in such a way that in a first method step, a through hole is created in the valve seat element (26), and in a second method step, from the ejection end of the through hole, an outlet region is created that is altered in shape and/or size and/or contour compared to the through hole.
