    摘要: A device is used for measuring the injection quantity of injection nozzles. It includes a measuring chamber to which the injection nozzle can be coupled. In addition, a detection device is provided, which detects a state change of the testing fluid in the measuring chamber due to an injection by the injection nozzle. In order to be able to measure the injection quantity without wear and in a highly precise manner, the invention provides that the detection device has a capacitor, whose one electrode is comprised of an electrically conductive fluid, which is at least partially contained in a volume connected to the measuring chamber. The processing unit is connected to the capacitor in such a way that it can detect a change in its capacitance, which is produced by a movement of the electrically conductive fluid.

    摘要: For measuring the injection quantity (Vm) of injection systems (18), in particular in internal combustion engines, test fluid (22) is injected by the injection system (18) into a measurement chamber (12). To increase the precision and stability of the measurement, the volume of the measurement chamber (12) is kept constant during the injection. Moreover, a gas volume (Vg) is present in the measurement chamber (12). The injected volume (Vm) of test fluid (22) is ascertained from the pressure change (dP) in the measurement chamber (12) that occurs upon an injection of test fluid (22). The ascertainment of the injected volume (Vm) is done by means of the state equation for ideal gases.

    摘要: A new process in which a valve closing body is produced with a predetermined inclination in relation to a longitudinal tool axis. The valve closing body is set in rotation and thereby carries out a precessing motion so that the tool body that rests against the sealing seat produces a narrow ball zone that always assures a sealing contact between the sealing seat and the valve seat face, even when a valve closing body is guided in the valve with guidance play. The process and the device are particularly suited for machining sealing seats on valve closing bodies of fuel injection valves for fuel injection systems of internal combustion engines.

    摘要: A method and a device for measuring the angular distribution of a liquid jet ejected from a spray element (5), particularly of a fuel jet ejected from a fuel injector, is proposed. Partial spray quantities are detected by catch containers at a plurality of measuring coordinates arranged in a spatially or planarly distributed manner. The catch containers each contain a plurality of measuring coordinates, and the measurement is carried out in a multiply repeated manner using catch containers, which are rotated about an axis of rotation with different angles of rotation.

    摘要: An apparatus for measuring hydraulic flow quantities and leaks in a specimen, including a measuring section to which the specimen is coupled and a capacitive sensor disposed in the measuring section. The measuring section can be acted upon both by at least one measurement medium and by at least one pressure medium. For generating a pressure acting on the measurement medium an inlet/outlet for the measurement medium is embodied on a side of the measuring section remote from the specimen, and an inlet/outlet for the pressure medium is disposed directly on the measuring section, on a side of the measuring section toward the specimen.
