A magnetic valve includes a valve body having a valve seat which can be closed by a sealing element, at least one outlet channel which leads into a fluid chamber of the magnetic valve, receiving the sealing element at least in parts, and a flow guiding element which surrounds the sealing element at least in parts. The sealing element is operatively connected to a magnet armature arranged in a magnet armature chamber embodied on one side of the flow guiding element facing away from the fluid chamber. The valve body and the flow guiding element together form at least one connection channel producing a fluidic connection between the fluid chamber and the magnet armature chamber.

1. A solenoid valve, comprising: a valve body including a valve seat closable by means of a sealing element, and defining at least one outlet duct issuing into a fluid space, the valve body being configured to receive at least a portion of the sealing element; anda flow guide element at least partially surrounding the sealing element,wherein the sealing element is operatively connected to a magnet armature arranged in a magnet armature space formed on a side of the flow guide element which faces away from the fluid space,wherein the valve body and the flow guide element jointly form at least one connecting duct making a fluid connection between the fluid space and the magnet armature space,wherein at least one radial duct is defined in the valve body fluidly connecting the outlet duct and the connecting duct,wherein a bearing surface of the flow guide element rests against a surface of the valve body on a side of the fluid space opposite the magnet armature,wherein the radial duct is partially defined by the bearing surface of the flow guide element,wherein the flow guide element includes an at least partially curved flow guide surface configured to guide flow toward the outlet duct, andwherein the flow guide element includes a disk portion and an annular portion extending axially from an outer edge of the disk portion, and the at least partially curved flow guide surface is arranged between the disk portion and the annular portion. 2. The solenoid valve as claimed in claim 1, wherein the connecting duct is defined between an inner wall of the valve body and an outer wall of the flow guide element. 3. The solenoid valve as claimed in claim 1, wherein at least one of an inner wall of the valve body and an outer wall of the flow guide element has a recess that defines the connecting duct. 4. The solenoid valve as claimed in claim 1, wherein at least one of the connecting duct and the radial duct are at least in regions round in cross section. 5. The solenoid valve as claimed in claim 1, wherein the flow guide element is composed of metal or of plastic. 6. The solenoid valve as claimed in claim 1, wherein the flow guide element is made as a stamped and bent part or as an injection molding. 7. The solenoid valve as claimed in claim 1, further comprising: an alignment means for aligning the flow guide element in the fluid space in the circumferential direction. 8. The solenoid valve as claimed in claim 1, wherein the radial duct is defined by a radially extending cutout in the valve body. 9. The solenoid valve as claimed in claim 1, wherein the outlet duct is defined in an axial direction in the valve body. 10. A driver assistance device, comprising: at least one solenoid valve, including (i) a valve body having a valve seat closable by means of a sealing element, and defining at least one outlet duct issuing into a fluid space, the valve body being configured to receive at least a portion of the sealing element, and (ii) a flow guide element at least partially surrounding the sealing element,wherein the sealing element is operatively connected to a magnet armature arranged in a magnet armature space formed on a side of the flow guide element which faces away from the fluid space,wherein the valve body and the flow guide element jointly form at least one connecting duct making a fluid connection between the fluid space and the magnet armature space,wherein at least one radial duct is defined in the valve body fluidly connecting the outlet duct and the connecting duct,wherein a bearing surface of the flow guide element rests against a surface of the valve body on a side of the fluid space opposite the magnet armature,wherein the radial duct is partially defined by the bearing surface of the flow guide element,wherein the flow guide element includes an at least partially curved flow guide surface configured to guide flow toward the outlet duct, andwherein the flow guide element includes a disk portion and an annular portion extending axially from an outer edge of the disk portion, and the at least partially curved flow guide surface is arranged between the disk portion and the annular portion.
