Abstract

An apparatus for the treatment of water includes an elongated housing having a first end and a second end. The first end has a water inlet and the second end has a water outlet. An elongated ultraviolet radiation source with a sleeve is concentrically located within the elongated housing. The elongated ultraviolet radiation source has, at its first end, electrical connections, which extend through the second end of the housing and have a second free end held in a support element. The support element includes a supporting structure containing a ring element and from thereon radially inwardly running arms. The arms are designed in such a way that during assembly the arms are resiliently deformed and wherein, if assembled, the arms are pressed against the sleeve, so that the free end of the ultraviolet radiation source is held by the arms in a resilient manner.

First claim

The invention claimed is:

1. An apparatus for the treatment of water, said apparatus comprising:
an elongated housing having a first housing end and a second housing end, said first housing end having a first water conduit and said second housing end having a second water conduit;
an elongated ultraviolet radiation source with a sleeve located within the elongated housing, said elongated ultraviolet radiation source having a first end with electrical connections and a second free end; and
a support element that supports the second free end,
wherein the support element comprises a supporting structure containing a ring element and resiliently deformable arms extending radially inwardly from the ring element, wherein each of the deformable arms has a first end which is fixed to the ring element and a tip portion, and wherein the second free end of the elongated ultraviolet radiation source is resiliently held by the tip portions of the arms.

2. The apparatus according to claim 1 , wherein a diameter of the sleeve is between 40% and 60% of a diameter of the ring element.

3. The apparatus according to claim 1 , wherein the arms are equally spaced in a peripheral direction of the ring element.

4. The apparatus according to claim 1 , wherein the arms are oblong and equally shaped.

5. The apparatus according to claim 1 , wherein, in a relaxed state of the arms, inner ends of the arms form a substantially circular opening with a diameter less than a diameter of the sleeve.

6. The apparatus according to claim 1 , wherein the supporting structure has at least six arms.

7. The apparatus according to claim 1 , wherein the supporting structure has spacers extending radially outward of the ring element.

8. The apparatus according to claim 7 , wherein the spacers are equally spaced in a peripheral direction of the ring element and a free circumferential surface of the ring element predominates.

9. The apparatus according to claim 1 , wherein the support element comprises flaps arranged on a second set of arms that extend radially outward of the ring element.

10. The apparatus according to claim 9 , wherein the flaps are angulated so that the flaps do not radially project over the supporting structure.

11. The apparatus according to claim 9 , wherein each flap extends from one of the arms of the second set of arms at a location that is about half of a length of said one of the arms of the second set of arms.

12. The apparatus according to claim 9 , wherein each arm of the second set of arms is substantially rectangular with an oblong shape.

13. The apparatus according to claim 9 , wherein the support element has at least four of said flaps, each flap being arranged on one arm of the second set of arms, wherein the second set of arms are equally distributed along a circumference of the ring element.

14. The apparatus according to claim 1 , wherein the support element is a one-piece stamped and bent part.

15. The apparatus according to claim 1 , wherein the sleeve constitutes glass of an ultraviolet lamp or an additional sleeve tube surrounding the radiation source.
