Abstract

A water jet deliver disk in kitchen sprayer, comprising a first element, made of a rigid material such as plastic, and constituted by a peripheral body fixable to the sprayer body, by a hub adapted to convey a central jet, and by cross-members connecting the peripheral body and the hub in a monolithic structure and arranged to provide water passage openings, and a second annular element, made of an elastic material and associated with the first element to embed the cross-members in the region between the peripheral body and the hub, and comprising holes for water passage which are arranged at the passage openings formed by the cross-members to provide jet.

Claims

1. A water jet delivery disk in kitchen sprayer, comprising:

a first element, made of a rigid material, which is constituted by a peripheral body, provided with fixing said first element to a sprayer body, by a hub which is designed to convey a central jet, and by cross-members extending between said peripheral body and said hub, with said peripheral body, said hub and said cross-members forming a monolithic body wherein said cross-members are arranged so as to form passage opening for water passage;

a second annular element, made of an elastic material, which is associated with the first element so as to completly embed said cross-members at least in a region between the peripheral body and the hub, and which comprises holes for the passage of water arranged at said passage openings formed by the cross-members to provide a rim jet, said second annular element being further provided with a protrusion which protrudes from a surface thereof that is directed toward the outside of the sprayer at an outlet section of each one of said holes.

2. The disk of claim 1, wherein said second element is associated with the first element by simultaneous molding.

3. The disk of claim 1, wherein the second element is associated with the first element by overmolding.

4. The disk of claim 1, wherein said peripheral body and said hub have, in a region thereof adapted to be crossed by water before entering said holes of the second element, respective facing cylindrical walls, said second annular element further comprising covering protusions which extend monolithically therefrom along said facing walls to end at a free end thereof with curled lips which engage at a surface of the disk.

5. A water jet delivery disk in a kitchen sprayer, comprising:

a first element, including a peripheral body, provided with fixing means for fixing said first element to a sprayer body, a hub formed so as to convey a water central jet, and cross-members extending between said peripheral body and said hub, with said peripheral body, said hub and said cross-members are provided as a monolithic structure made of a rigid material, and wherein said cross-members extend between said peripheral body and said hub so as to form passage openings which allow water passage;

a second annular element, made of an elastic material, which is associated with the first element so as to be molded over and embed completely said cross-members at least at a region located between the peripheral body and the hub, and which comprises holes for the passage of water arranged at said passage openings formed by the cross-members to provide a rim jet, said second annular element being further provided with an elastically deformable protusion which protudes from a surface thereof that is directed toward the outside of the sprayer at an outlet section of each one of said holes so as to be accessible for manual deformation and scale deposit breaking up.

6. The disk of claim 5, wherein the second element is associated with the first element by simultaneous molding.

7. The disk of claim 5, the second element is associated with the first element by overmolding.

8. The disk of claim 5, wherein said peripheral body and said hub have, in a region thereof adapted to be crossed by water before entering said holes of the second element, respective facing cylindrical walls, said second annular element further comprising covering protusions which extend monolithically therefrom along said facing walls to end at a free end thereof with curled lips which engage at a surface of the disk.
