摘要

The valve arrangement (1) has housing (20) with spraying holes (11) and a pressure chamber (18), where an inner element (21) is arranged in the housing. A priming valve (3) is provided with a priming valve needle (5), an anchor (24), a priming valve spring (6), a priming valve seat (9) and an electromagnetic actuator.
