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.

Abstract: A coolant valve for a motor vehicle. The coolant valve includes a housing with an inlet and an outlet, a valve seat which surrounds a flow cross-section formed between the inlet and the outlet, and a control body which is placeable on and liftable off the valve seat via an actuator. The control body has through-going bores via which the inlet is continuously connected to a chamber on a side of the control body which faces away from the inlet, a first annular protrusion which axially extends towards the valve seat and via which the control body is placed on the valve seat, a wall which extends radially between the first annular protrusion and the through-going bores, and an axial groove which extends in a circumferential direction and which is delimited radially to an outside by the first annular protrusion and radially to an inside by the wall.
