Abstract

A shower spray device is described in which the side wall of the water distribution chamber consists of a sealing element.

Claims

1. A shower spray device having at least one water distribution chamber in fluid communication with at least one water inlet and with a plurality of water outlet nozzles, said chamber including at least one lower plate housing said outlet nozzles and at least one upper plate in which said inlet is provided, wherein at least the side wall of said distribution chamber consists wholly or partly of a sealing element interposed between said plates, and wherein said sealing element is an elastic sealing element, at least an outer circumferential part of the elastic sealing element remaining exposed external to the distribution chamber even after the lower and upper plates and elastic sealing element have been assembled.

2. A device as claimed in claim 1, wherein said sealing element includes an O-ring.

3. A device as claimed in claim 1, wherein said plates are superimposed to constitute a lower wall and an upper wall respectively of said chamber and retain said sealing element between them.

4. A device as claimed in claim 1, wherein said plates are flat.

5. A device as claimed in claim 1, wherein said plates have substantially similar shapes and dimensions.

6. A device as claimed in claim 1, wherein said plates have similar shapes and slightly different dimensions.

7. A device as claimed in claim 1, wherein at least one of said plates comprises at least one groove for housing said sealing element.

8. A device as claimed in claim 1, wherein at least one of said plates comprises a machined inner surface portion in correspondence to the resting area of said sealing element.

9. A device as claimed in claim 1, wherein said nozzles are made of elastic material.

10. A device as claimed in claim 9, wherein the elastic material includes rubber or like materials.

11. A device as claimed in claim 1, wherein each of said nozzles comprises at one end a perimeter flange designed to be housed in a corresponding seat obtained inside said lower plate.

12. A device as claimed in claim 11, further comprising a fixing device to retain in position each of said nozzles by blocking said perimeter flange in the respective housing seat.

13. A device as claimed in claim 1, wherein at least one connection element is mounted in correspondence to said inlet.

14. A device as claimed in claim 1, further comprising a tightening device to retain said plates in a reciprocally superimposed position.

15. A device as claimed in claim 14, wherein said tightening device is mounted in correspondence to said connection element.

16. A shower spray device having at least one water distribution chamber in fluid communication with at least one water inlet and with a plurality of water outlet nozzles, wherein:

at least the side wall of said distribution chamber consists wholly or partly of a sealing element such that at least a portion of the sealing element remains exposed external to the distribution chamber even after assembly of the shower spray device,

wherein each of said nozzles comprises at one end a perimeter flange designed to be housed in a corresponding seat obtained inside a plate; and

wherein a fixing device is provided to retain in position each of said nozzles by blocking said perimeter flange in the respective housing seat.

17. A shower spray device having at least one water distribution chamber in fluid communication with at least one water inlet and with a plurality of water outlet nozzles, said chamber including at least one lower plate housing said outlet nozzles and at least one upper plate in which said inlet is provided, wherein at least a side wall of said distribution chamber consists wholly or partly of a sealing element interposed between said plates, and wherein said sealing element is an elastic sealing element forming at least part of a sidewall of the spray device;

wherein at least one of said plates comprises at least one groove for housing said sealing element;

wherein the upper lower plates are flat and have substantially similar shapes; and

wherein at least an outer circumferential part of the elastic sealing element is exposed external to the distribution chamber.

18. A device as claimed in claim 17, wherein the externally exposed outer circumferential part of the elastic sealing element forms at least a part of the side wall of the said distribution chamber.
