Valve for measuring out fluid, for use as injection valve for injecting fuel into suction tube, has fluid flow-blocking cover made of transparent plastic material for measuring beams of optical measuring system

The valve has a hollow filter body (41) containing high axial rigidity, formed with a longitudinally continuous central cavity (43) and arranged with a fluid flow-blocking cover (42) arranged in the cavity. The fluid flow-blocking cover is made of transparent plastic material such as Bergamid (RTM:...

Beschreibung
Zusammenfassung:The valve has a hollow filter body (41) containing high axial rigidity, formed with a longitudinally continuous central cavity (43) and arranged with a fluid flow-blocking cover (42) arranged in the cavity. The fluid flow-blocking cover is made of transparent plastic material such as Bergamid (RTM: Polyamide compounds) polybutylene terephthalate or Ultramid (RTM: polyamide molding compounds) for measuring beams of an optical measuring system. The cover in the cavity is arranged along axles of the filter body. Es wird ein Ventil zum Zumessen von Fluid angegeben, das einen Filter (40) mit einem vom Fluid durchströmbaren Filterkörper (41) und einem einen längsdurchgehenden, zentralen Hohlraum (43) im Filterkörper (41) gegenüber dem Fluid absperrenden Abdeckelement (42) aufweist. Um optische Messungen der Ventilnadelbewegung im Ventil bei in das Ventil eingesetztem Filter (40) vornehmen zu können, besteht das Abdeckelement (42) aus einem Kunststoff, der für Messstrahlen des optischen Messsystems transparent ist.
