Abstract

A solenoid valve is proposed, having a substantially circular cross-sectional shape orthogonally in relation to an effective axis of the solenoid valve, it being possible for valve devices of the solenoid valve to be connected to one another by means of joining operations directed substantially in the direction of the effective axis, the valve devices having such peripheral shapes that the valve devices can be centered with respect to one another by means of the joining operations.

Claims

1. A solenoid valve (100) with a substantially circular cross-sectional shape orthogonally in relation to an effective axis of the solenoid valve (100), the solenoid valve (100) including a first, a second, and a third valve device (10, 20, 30) connected to one another by threadless joining operations directed substantially in the direction of the effective axis, the valve devices (10, 20, 30) having peripheral shapes such that the valve devices (10, 20, 30) can be centered with respect to one another by the threadless joining operations, wherein the first valve device (10) includes a lifting magnet, the second valve device (20) includes a housing for the first valve device (10), and the third valve device (30) includes a valve housing to which the second valve device (20), joined together with the first valve device (10), is coupled, wherein the second valve device (20) includes a first closed end and a second open end spaced along the effective axis from the first closed end, a portion of the first valve device (10) protruding out of the second open end, wherein the second valve device (20) is coupled to the third valve device (30) at the second open end, and wherein the third valve device (30) includes a fluid inlet and a fluid outlet.

2. The solenoid valve according to claim 1, wherein the first valve device (10) includes a lifting rod (11) operable to center elements (12, 13, 14, 15, 16) arranged in series on the lifting rod (11).

3. The solenoid valve according to claim 2, wherein the lifting magnet has a fixing element (17) for the mechanical fixing of the elements (12, 13, 14, 15, 16) arranged in series on the lifting rod (11).

4. The solenoid valve according to claim 2, wherein the lifting rod (11) is produced by a multi-component injection-molding process.

5. The solenoid valve according to claim 4, wherein the lifting rod (11) has a sealing element (11a) on a sealing portion.

6. The solenoid valve according to claim 2, wherein the second valve device (20) includes a centering means (21) for a magnet coil (22).

7. The solenoid valve according to claim 6, wherein the centering means (21) is formed in a tubular manner integrally with the second valve device (20).

8. The solenoid valve according to claim 6, wherein the second valve device (20) has a first positioning means (23) for a connector device (24), through which the magnet coil (22) can be supplied with energy.

9. The solenoid valve according to claim 8, wherein the second valve device (20) has a second positioning means (25) for positioning the first valve device (10) in the second valve device (20).

10. The solenoid valve according to claim 4, wherein the third valve device (30) includes a third positioning means (27) for the second valve device (20).

11. The solenoid valve according to claim 10, wherein the third positioning means is formed as clearances in the third valve device (30) for retaining elements (26) of the second valve device (20).

12. The solenoid valve according to claim 11, wherein the retaining elements (26) are formed in such a way that, after a joining together of the second valve device (20) with the third valve device (30), the retaining elements (26) receive a force, acting along the effective axis, between the first valve device (10) and the second valve device (20).

13. The solenoid valve according to claim 12, wherein the third valve device (30) has a locking device (28), by which the second valve device (20) can be made to engage with the third valve device (30) after the joining together with the third valve device (30) and a turning operation in relation to the third valve device (30).

14. The solenoid valve according to claim 1, wherein the joining operations are weldless.

15. A solenoid valve (100) with a substantially circular cross-sectional shape orthogonally in relation to an effective axis of the solenoid valve (100), the solenoid valve (100) including a first, a second, and a third valve device (10, 20, 30) connected to one another by weldless joining operations directed substantially in the direction of the effective axis, the valve devices (10, 20, 30) having peripheral shapes such that the valve devices (10, 20, 30) can be centered with respect to one another by the weldless joining operations, wherein the first valve device (10) includes a lifting magnet, the second valve device (20) includes a housing for the first valve device (10), and the third valve device (30) includes a valve housing to which the second valve device (20), joined together with the first valve device (10), is coupled, wherein the second valve device (20) includes a first closed end and a second open end spaced along the effective axis from the first closed end, a portion of the first valve device (10) protruding out of the second open end, wherein the second valve device (20) is coupled to the third valve device (30) at the second open end, and wherein the third valve device (30) includes a fluid inlet and a fluid outlet.
