The inlet conduit and/or outlet conduit are in fluidic communication with a valve seat of the magnet valve. According to the invention in the valve body, a receptacle region is provided, in which an insert part having or embodying the inlet conduit and/or the outlet conduit in at least some regions is disposed. The invention further relates to a driver assistance system having such a magnet valve. ## Claims ### Claim 1 A magnet valve comprising: a valve body including a first end portion defining a fluid chamber, a second end portion defining a receptacle region, and a wall portion between the fluid chamber and the receptacle region having a first surface that forms a bottom face of the fluid chamber and a second surface that forms an inner end of the receptacle region, the wall portion including a valve seat formed in the bottom face of the fluid chamber, a supply opening formed in the inner end of the receptacle region, and a fluid conduit that fluidly connects the valve seat and supply opening, the second end portion including at least one fluid port that is fluidly connected to the receptacle region, and an insert part received in the receptacle region, the insert part including a fluid conduit that fluidly connects the at least one fluid port to the supply opening. ### Claim 2 (depends on 1) The magnet valve as defined by claim 1, wherein the insert part has at least one axial outlet recess, which is connected to an outlet opening that extends through the wall portion of the valve body to the fluid chamber, and the axial outlet recess and the outlet opening each form one region of an outlet conduit. ### Claim 3 (depends on 2) The magnet valve as defined by claim 2, wherein the axial outlet recess is embodied by an at least regionally embodied setback on an outer surface of the insert part and/or an inner surface of the valve body. ### Claim 4 (depends on 1) The magnet valve as defined by claim 1, wherein the second end portion of the valve body includes at least one inlet port, wherein the fluid conduit in the insert part fluidly connects the at least one inlet port to the supply opening, and wherein the insert part has a central axial inlet recess that forms a portion of the fluid conduit. ### Claim 5 (depends on 4) The magnet valve as defined by claim 4, wherein the axial inlet recess is a blind recess, wherein the at least one inlet port are arranged radially with respect to the receptacle region, and wherein the insert part includes at least one radial inlet recess fluidly connected to the axial inlet recess and that extend through a jacket face of the insert part to the at least one inlet port. ### Claim 6 (depends on 5) The magnet valve as defined by claim 5, wherein each of the radial inlet recesses are fluidly connected to a through opening provided in a wall of the second end portion of the valve body and which lead to a fluid inlet port. ### Claim 7 (depends on 6) The magnet valve as defined by claim 6, wherein the second end portion of the valve body includes at least one axial output port, wherein the wall portion defines at least one outlet opening spaced apart from the valve seat that fluidly connects the fluid chamber to the receptacle region, and wherein the insert part has at least one axial outlet recess that fluidly connects the at least one outlet opening to the at least one outlet port. ### Claim 8 (depends on 7) The magnet valve as defined by claim 7, wherein the insert part includes an inner end portion oriented toward the inner end of the receptacle region and an outer end portion oriented toward the at least one outlet port, wherein each of the axial outlet recesses is embodied by a setback on the insert part and/or the second end portion of the valve body that forms a gap between an outer wall of the insert part and an inner wall of the receptacle region that extends from the inner end portion to the outer end portion of the insert part. ### Claim 9 (depends on 1) The magnet valve as defined by claim 1, wherein the insert part has a central axial inlet recess that embodies the fluid conduit and adjoins the supply opening associated with the valve seat. ### Claim 10 (depends on 9) The magnet valve as defined by claim 9, wherein the insert part has at least one axial outlet recess, which is connected to an outlet opening that extends through the wall portion of the valve body to the fluid chamber, and the axial outlet recess and the outlet opening each form one region of an outlet conduit. ### Claim 11 (depends on 10) The magnet valve as defined by claim 10, wherein the axial outlet recess is embodied by an at least regionally embodied setback on an outer surface of the insert part and/or an inner surface of the valve body. ### Claim 12 (depends on 9) The magnet valve as defined by claim 9, wherein the axial inlet recess is a blind recess and is in fluidic communication with at least one radial inlet recess, the at least one radial inlet recess discharging through a jacket face of the insert part, the at least one radial inlet recess forming a further region of the inlet conduit. ### Claim 13 (depends on 12) The magnet valve as defined by claim 12, wherein the insert part has at least one axial outlet recess, which is connected to an outlet opening that extends through the wall portion of the valve body to the fluid chamber, and the axial outlet recess and the outlet opening each form one region of an outlet conduit. ### Claim 14 (depends on 13) The magnet valve as defined by claim 13, wherein the axial outlet recess is embodied by an at least regionally embodied setback on an outer surface of the insert part and/or an inner surface of the valve body. ### Claim 15 (depends on 12) The magnet valve as defined by claim 12, wherein the at least one radial inlet recess is connected to through opening provided in an outer wall of the valve body and which has a fluid inlet port. ### Claim 16 (depends on 15) The magnet valve as defined by claim 15, wherein a base of the insert part is secured to the valve body using at least one of a form-locking, force-locking and material-locking connection. ### Claim 17 (depends on 15) The magnet valve as defined by claim 15, wherein a base of the insert part is secured to the valve body using at least one of a form-locking, force-locking and material-locking connection. ### Claim 18 (depends on 15) The magnet valve as defined by claim 15, wherein the insert part has at least one axial outlet recess, which is connected to an outlet opening that extends through the wall portion of the valve body to the fluid chamber, and the axial outlet recess and the outlet opening each form one region of an outlet conduit. ### Claim 19 (depends on 18) The magnet valve as defined by claim 18, wherein the axial outlet recess is embodied by an at least regionally embodied setback on an outer surface of the insert part and/or an inner surface of the valve body. ### Claim 20 (depends on 15) The magnet valve as defined by claim 15, wherein the insert part has a base for securing the insert part to the valve body in the receptacle region. ### Claim 21 (depends on 20) The magnet valve as defined by claim 20, wherein a base of the insert part is secured to the valve body using at least one
