Abstract

A solenoid valve for controlling a fluid has a first housing part (2) and an axial guide (3) facing inwards for an armature (4) that can be displaced in the axial guide (3) under the effect of a solenoid (5) that at least partially surrounds the exterior of the first housing part (2). A return spring (6) and a closing element (27) impact a valve closing element (7). A second housing part (9) is arranged coaxially to the first housing part (2). The first housing part (2) has a reduced wall portion (17) that faces inwards towards the armature (4) and the second housing part (9) and that effects a magnetic separation of the two housing parts (2, 9) to at least some extent.
