초록 ▼

For a coaxial magnetic valve with an inner valve disk which can move in the axial direction, and with an outer valve disk which surrounds the inner valve disk and which can move in the axial direction, wherein these two valve disks are arranged coaxially to each other and each rises from its corresponding valve seat against the action of a closing spring, and with a magnetic drive for activating both valve disks, the magnetic drive includes two independent magnetic loops which are arranged one above the other in the axial direction, each of which has a coil, and they interact with two armatures which are arranged one above the other in the axial direction and which connect to the inner valve disk or to the outer valve disk, wherein the armature of the outer valve disk is penetrated by a connecting rod connecting the inner valve disk to its armature. With this double magnetic valve, each valve disk can be controlled separately.

1. A coaxial magnetic valve comprising:an inner valve disk which can move in an axial direction;an outer valve disk which surrounds the inner valve disk and which can move in the axial direction wherein the two valve disks are arranged coaxially to each other and each rises from its corresponding valve seat against the action of a closing spring; anda magnetic drive for activating both valve disks, the magnetic drive including two independent magnetic loops which are arranged one above the other in the axial direction, each magnetic loop having a coil, the magnetic loops interacting with two armatures which are arranged one above the other in the axial direction and which are each connected to the inner valve disk or to the outer valve disk, wherein the armature of the outer valve disk is penetrated by a connecting rod connecting the inner valve disk to its armature. 2. The coaxial magnetic valve according to claim 1, wherein the outer valve disk and its armature are directly connected to each other. 3. The coaxial magnetic valve according to claim 1, wherein a nonmagnetic spacer is provided between the two magnetic loops. 4. The coaxial magnetic valve according to claim 1, wherein the two armatures are guided in a nonmagnetic closed magnet sleeve or in magnetic sleeves. 5. The coaxial magnetic valve according to claim 4, wherein the closed magnet sleeve or parts of this sleeve are formed as a stainless steel pipe. 6. The coaxial magnetic valve according to claim 4, wherein one end of the closed magnet sleeve is sealed by the pole core for the armature of the inner valve disk. 7. The coaxial magnetic valve according to claim 6, wherein the pole core for the armature of the outer valve disk is mounted in the closed magnet sleeve, in particular forced into the sleeve, and is penetrated by the connecting rod. 8. The coaxial magnetic valve according to claim 1, wherein the connecting rod penetrates the armature of the outer valve disk and/or its pole core concentrically. 9. The coaxial magnetic valve according to claim 1, wherein the intermediate space between the inner and outer valve disks is sealed by gaskets on the armature of the outer valve disk and on the connecting rod. 10. A coaxial magnetic valve comprising:an inner valve disk movable in an axial direction;an outer valve disk surrounding the inner valve disk and being movable in the axial direction wherein the inner and outer valve disks are arranged coaxially to each other; anda magnetic drive operable to activate one valve disk independent of the other valve disk, the magnetic drive including:first and second magnetic loops arranged one above the other in the axial direction; andfirst and second armatures respectively connected to the inner valve disk and the outer valve disk, the first and second armatures being arranged one above the other in the axial direction and being respectively associated with the first and second magnetic loops. 11. The coaxial valve disk according to claim 10, further comprising a connecting rod connecting the inner valve disk to the first armature and penetrating the second armature connected to the outer valve disk. 12. The coaxial magnetic valve according to claim 10, wherein the outer valve disk and the second armature are directly connected to each other. 13. The coaxial magnetic valve according to claim 10, further comprising a nonmagnetic spacer disposed between the first and second magnetic loops. 14. The coaxial magnetic valve according to claim 10, further comprising a closed magnet sleeve guiding the first and second armatures. 15. The coaxial magnetic valve according to claim 14, further comprising a pole core for the first armature which seals one end of the closed magnet sleeve pole. 16. The coaxial magnetic valve according to claim 10, further comprising a connecting rod connecting the inner valve disk to the first armature and concentrically penetrating the second armature connected to the outer valve disk.
