带有引导元件的阀组件
摘要：
本发明涉及带有引导元件的阀组件。详细说明了用于流体喷射阀的阀组件(1)。其包括将流体入口(12)液压地连接至喷射口(14)的中空阀体(10)并且具有纵向轴线(L)。阀针(20)以可轴向位移的方式接收在阀体(10)中用于在闭合位置中密封喷射口(14)。其还包括用于使所述阀针(20)移离闭合位置的电磁致动器组件(30),致动器组件(30)包括可移动的衔铁(32)和相对于阀体(10)在位置上固定的极片(34)。引导元件(40)相对于极片(34)在位置上固定,且具有用于轴向地引导衔铁(32)的第引导表面(401)和用于轴向地引导阀针(20)的第二引导表面。
摘要（英）：

A valve assembly (1) for a fluid injection valve is specified. It comprises a hollow valve body (10) which hydraulically connects a fluid inlet (12) to an injection orifice (14) and has a longitudinal axis (L) . A valve needle (20) received in the valve body (10) in axially displaceable fashion for sealing the injection orifice (14) in a closing position. It further comprises an electromagnetic actuator assembly (30) for displacing the valve needle (20) away from the closing position, the actuator assembly (30) comprising a movable armature (32) and a pole piece (34) which is positionally fix relative to the valve body (10). A guide element (40) is positionally fix relative to the pole piece (34), has a first guide surface (401) for axially guiding the armature (32) and a second guide surface (403) for axially guiding the valve needle (20).
