Abstract

A solenoid valve for a motor vehicle. The solenoid valve includes a housing having an inlet and an outlet, a flow cross-section formed between the inlet and the outlet, a valve seat which surrounds the flow cross-section, a valve unit having an axial contact surface, a coupling member, and a control body, an electromagnetic actuator having an armature with a first axial end which bears against the axial contact surface of the valve unit, a second axial end, and an axial through bore through which the coupling member of the valve unit projects so as to be movable with the armature, and a fastening element which bears on the second axial end of the armature and which is fixedly connected to the coupling member of the valve unit. The valve unit is set down on the valve seat and is lifted from the valve seat.
