Pressure-measuring device for a common-rail system has single-shot reservoirs, chambers and a measuring cell for detecting pressure levels

摘要

A first chamber (FC) (12) links to an inner space (IS) (14) of a single-shot reservoir (7) via a throttle shutter (13). A measuring cell (15) detects a first pressure level (p1) in the FC as well as a pressure level (pE) for a single-shot reservoir in the IS of the single-shot reservoir. There is a second chamber (17) where the measuring cell detects a pressure level for a single-shot reservoir.
