摘要： Zum Messen der Einspritzmenge (Vm) von Einspritzsystemen (18), insbesondere von Brennkraftmaschinen, wird Prüffluid (22) von dem Einspritzsystem (18) in eine Messkammer (12) eingespritzt. Um die Messgenauigkeit und die Stabilität der Messung zu erhöhen, wird das Volumen der Messkammer (12) während der Einspritzung konstant gehalten. Weiterhin ist in der Messkammer (12) ein Gasvolumen (Vg) vorhanden. Das eingespritzte Volumen (Vm) an Prüffluid (22) wird aus der Druckänderung (dP) in der Messkammer (12) ermittelt, welche sich bei einer Einspritzung von Prüffluid (22) ergibt. Die Ermittlung des eingespritzten Volumens (Vm) erfolgt mittels der Zustandsgleichung für ideale Gase.

摘要： In order to measure the amount injected (Vm) by an injection system (18), particularly in an internal combustion engine, a test fluid (22) is injected into a measuring chamber (12) by the injection system (18). The volume in the measuring chamber (12) is kept constant during injection so that measuring precision and stability of the measurement increases. Additionally, a gas volume (Vg) is provided in the measuring chamber (12). The injected volume (Vm) of the test fluid (22) is determined from the alteration in pressure (dP) in the measuring chamber (12) which is produced when injecting the test fluid (22). The injected volume (Vm) is determined by state equation for ideal gases.

摘要： The aim of the invention is to measure the angular distribution of a liquid spray which is sprayed by a spraying element (5), especially of a fuel spray which is sprayed by a fuel injection valve. To this end, partial sprayed quantities are measured by means of collecting vessels (2) at several measuring coordinates which are distributed in a three-dimensional or two-dimensional manner. The collecting vessels respectively comprise several measuring coordinates and the measurement is repeatedly carried out using collecting vessels (2) which are turned around an axis of rotation (6) with different angles of rotation.

摘要： Valve obturators have a sealing surface which is designed to rest against the valve seat. As a result of the unavoidable play in the obturator mounting, the line seal between the sealing surface and the valve seat is not tight. In the production method proposed, the obturator (1) is rotated at a given angle to the longitudinal axis (28) of the machining tools and thus executes a precessional motion so that the tool (38), resting against the sealing surface, produces a narrow spherically curved zone which, even when there is play in the obturator mounting, always ensures that the sealing surface forms a tight seal with the valve seat. The method and device are particularly suitable for machining sealing surfaces on obturators in fuel-injection valves in internal-combustion engines.

摘要： The invention relates to a device for measuring hydraulic discharge and leakage in a test piece, comprising a measuring section configured as an inflow pipe approximately perpendicular to the test piece and a capacitive sensor located on the measuring section. Said sensor can be impinged upon by both at least one measuring medium and at least one other medium (pressure medium) designed to generate a pressure acting on the measuring medium. The invention aims to improve said device in such a way that it is possible to carry out precise measurements of discharge volumes and leakages using simple technology. To this end, the invention provides for the test piece to be coupled directly to the measuring section.
