Abstract
Ein Ventilblock (15) in einem System (10) zur Bestimmung der Druchflussmenge eines Kraftstoffeinspritzventils (1) weist eine Adapterplatte (19) sowie ein Gehäuseteil (21) auf. Von der Adapterplatte (19) und dem Gehäuseteil (21) wird ein Raum (22) ausgebildet, in dem ein Gasdruck anliegt. Die Adapterplatte (19) ist in einem Fortsatz (25; 25a) von einem schlauchförmigen Ventilglied (40) umgeben, welches Auslassbohrungen (28) und Einlassbohrungen (31) verschließt. Der erfindungsgemäße Ventilblock (15) ist besonders resistent gegenüber Verschmutzungen und weist eine hohe Lebensdauer auf.A valve block (15) in a system (10) for determining the flow rate of a fuel injection valve (1) has an adapter plate (19) and a housing part (21). From the adapter plate (19) and the housing part (21), a space (22) is formed, in which a gas pressure is applied. The adapter plate (19) is surrounded in a projection (25; 25a) by a tubular valve member (40) which closes outlet bores (28) and inlet bores (31). The valve block (15) according to the invention is particularly resistant to contamination and has a long service life.
Description
Die
Erfindung betrifft ein Durchflussventil nach dem Oberbegriff des
Anspruchs 1, wie es aus der
Ferner sind Einrichtungen zur Durchflussmessung von Kraftstoffeinspritzventilen bekannt. Eine derartige Einrichtung muss, um die ordnungsgemäße Funktion eines Kraftstoffeinspritzventils beurteilen zu können, die Menge an Kraftstoff bzw. Prüfmedium messen, die vom Kraftstoffeinspritzventil bei einem einzigen Kraftstoffeinspritzimpuls abgegeben wird, d.h. in der Regel eine Menge an Kraftstoff oder Medium im Bereich von einigen Milligramm. Die bekannte Einrichtung weist dazu neben einem Messblock einen zusätzlichen Ventilblock auf, der mit dem Messblock verbunden ist. Der Ventilblock dient dazu, die während der Messung im Messblock sich ansammelnden Mengen an Kraftstoff bzw. Medium aus der Einrichtung auszuschleusen.Further are devices for flow measurement of fuel injection valves known. Such a device must be in order to function properly To be able to judge a fuel injection valve, the amount of fuel or test medium measured by the fuel injector at a single fuel injection pulse is discharged, i. usually a lot of fuel or medium in the range of a few milligrams. The known device has to an addition block next to an additional valve block, the connected to the measuring block. The valve block is used to while the amount of fuel accumulating in the measuring block in the measurement block or medium out of the facility auszuschleusen.
Dazu weist der Ventilblock ein Ventilglied mit einem Ventilschieber auf, welcher eine metallische Dichtfläche im Ventilglied bildet. Das Öffnen und Schließen des Ventilglieds im Ventilblock erfolgt in Abhängigkeit von einem auf das Ventilglied einwirkenden Gasdruck. Beim Betrieb der bekannten Einrichtung hat sich herausgestellt, dass das Ventilglied im Ventilblock einem relativ hohen Verschleiß ausgesetzt ist, da die zur Messung verwendeten Kraftstoffeinspritzventile oftmals noch Fertigungsschmutz bzw. Späne aufweisen, die sich an der Dichtfläche des Ventilglieds absetzen bzw. dort zu Beschädigungen führen können.To the valve block has a valve member with a valve slide, which is a metallic sealing surface forms in the valve member. The opening and closing the valve member in the valve block is carried out depending on a on the Valve member acting gas pressure. When operating the known device has been found that the valve member in the valve block a exposed to relatively high wear is because the fuel injection valves used for measurement often still manufacturing dirt or chips have, which settle on the sealing surface of the valve member or there to damage to lead can.
Vorteile der ErfindungAdvantages of invention
Das erfindungsgemäße Durchflussventil mit den kennzeichnenden Merkmalen des Anspruchs 1 hat den Vorteil, dass es neben seiner Eignung zum Durchfluss von kleinsten Mengen an Medium unanfällig gegenüber Verschmutzungen jeglicher Art ist.The flow valve according to the invention with the characterizing features of claim 1 has the advantage that in addition to its suitability for the flow of smallest quantities unaffordable on medium across from Soiling of any kind is.
Vorteilhafte Weiterbildungen des erfindungsgemäßen Durchflussventils sind in den Unteransprüchen angegeben.advantageous Further developments of the flow valve according to the invention are in the subclaims specified.
