Electromagnetically actuated inlet valve and high-pressure pump with inlet valve

摘要

An electromagnetically actuatable inlet valve (24) for a high-pressure pump, in particular a fuel injection system, is proposed. The inlet valve (24) has a valve member (34) which is movable between an open position and a closed position. An electromagnetic actuator (60) is provided, through which the valve member (34) is movable, wherein the electromagnetic actuator (60) comprises a magnetic coil (64), a magnetic core (66) and an armature acting at least indirectly on the valve member (34) (68) which is displaceably guided in a receptacle (76) of a carrier element (78) in the direction of its longitudinal axis (69). The magnetic core (66) and the carrier element (78) are surrounded by a housing (70). In the housing (70) is in an intermediate space (94) between the housing (70) on the one hand and the carrier element (78) and / or the magnetic core (66) and / or a magnetic core (66) and the carrier element (78) interconnecting On the other hand, at least one sacrificial anode (96) is arranged connecting element (92). The at least one sacrificial anode (96) is electrically conductively connected to the carrier element (78) and / or the magnetic core (66) and / or the connecting element (92). The at least one sacrificial anode (96) consists of a less noble metal than the carrier element (78) and / or the magnetic core (66) and / or the connecting element (92).
