The invention relates to a valve, in particular a suction valve, in a high-pressure pump of a fuel injection system, having a valve element (14) which can be moved between an open position and a closed position and which is connected to a magnet armature (10) via an armature pin (8). An actuation force can be transmitted to the valve element (14) by the armature pin (8). The invention is characterized in that the armature pin (8) is partly introduced into a depression (24) of the magnet armature (10), and the armature pin (8) and the magnet armature (10) are connected together in a contact region (48) in a force-fitting manner by means of an interference fit (20). The armature pin (8) has a changing outer diameter (47), in particular a continuously changing outer diameter, along the contact region (48). 本发明涉及种在燃料喷射系统的高压泵中的阀、尤其抽吸阀，所述阀具有阀元件(14)，所述阀元件可在打开位态和关闭位态之间运动并且所述阀元件通过衔铁栓(8)与磁性衔铁(10)连接，其中，通过所述衔铁栓(8)可将操纵力传递到所述阀元件(14)上，其特征在于，所述衔铁栓(8)被部分地导入到所述磁性衔铁(10)的凹部(24)中并且所述衔铁栓(8)和所述磁性衔铁(10)借助在接触区域(48)中的压配合(20)力锁合地相互连接，并
