Valve arrangement for injection system in fuel injection system in motor vehicle, has valve piece shifted in valve piece guide, where medium flows toward flow path during divertion of medium toward guiding surface by seat

摘要

The arrangement (10) has a valve body (12) exhibiting a valve seat (14), where a pressuring medium flows through the valve body. The valve seat and a valve piece (17) form a sealing seat (21), where the valve piece is axially shifted in a valve piece guide (18). A flow path for the medium connects an area in front of a guiding surface and another area behind the guiding surface. The pressuring medium flows toward the flow path during divertion of the medium toward the guiding surface by the sealing seat. A valve seat body is designed as a ball (19). The flow path is designed as a longitudinal groove.
