Injector for injecting fuel

Injector for injecting fuel, comprising:

• a fuel feed line for introducing a fuel under high pressure,
• an active valve which can be actively switched and is configured to close or open at least one passage in order to selectively open or interrupt a flow connection from the fuel feed line to an area downstream of the active valve, and
• a passive valve which is arranged downstream of the active valve and can be passively switched into a closing state or releasing state by different pressure ratios applied upstream and downstream of the passive valve in order to release or interrupt a flow connection from upstream of the passive valve to an area downstream of the passive valve,
• wherein
• a reciprocating tappet of the passive valve comprises a permanent magnet or is a permanent magnet, and
• a tappet guide is provided for guiding the reciprocating movement of the tappet, which is electrically conductive and non-magnetizable or only weakly magnetizable, or
• a reciprocating tappet of the passive valve is electrically conductive and non-magnetizable or only weakly magnetizable, and
• a tappet guide is provided for guiding the reciprocating movement of the tappet, which comprises a permanent magnet or is a permanent magnet.
