Measurement device for measuring injection quantities in fuel injection systems has choke between measurement chamber and valve for emptying measurement chamber

摘要

The device has an injection nozzle (2) for injecting fluid into a measurement chamber (4) containing a measurement piston (5) and a valve (8) for emptying the measurement chamber, whereby the injection quantity is detected by determining the displacement of the piston. A choke (13) with a number of through openings (14) is arranged between the measurement chamber and the valve.
