Abstract

A sprayhead includes a body having a first end and a second end opposite the first end. The body includes a fluid inlet proximate the first end and a fluid outlet proximate the second end. The sprayhead includes a first disc fixed to the body and a second disc moveably coupled to the body. Rotation of the second disc relative to the first disc causes a first response. Translation of the second disc relative to the first disc causes a second response.

First claim

What is claimed is:

1. A sprayhead, comprising:
a cartridge;
an outlet disc fixed relative to the cartridge, the outlet disc having an inlet side and an outlet side having a first outlet port, a second outlet port, and a third outlet port; and
a movable disc having an inlet side fluidly coupled to a fluid inlet and having an outlet side adjacent and movable relative to the inlet side of the outlet disc, wherein the movable disc defines a passageway extending from the inlet side of the movable disc to the outlet side of the movable disc, wherein the movable disc is configured to rotate about an axis of rotation and configured to translate in a radial direction relative to the axis of rotation while the sprayhead is in use;
wherein movement in a first direction of the movable disc relative to the outlet disc fluidly couples the fluid inlet to at least one of the first outlet port, the second outlet port, and the third outlet port, and wherein movement in a second direction of the movable disc relative to the outlet disc controls a volume of fluid flowing from through the sprayhead.

2. The sprayhead of claim 1 , further comprising:
a lower body portion coupled to the movable disc; and
an upper body portion rotatably coupled to the lower body portion and interconnected with the outlet disc such that the upper body portion and the cartridge rotate together relative to the movable disc.

3. The sprayhead of claim 2 , wherein the first direction is a rotational direction, and wherein rotation of the upper body portion relative to the lower body portion selectively couples the fluid inlet to at least one of the first outlet port, the second outlet port, and the third outlet port.

4. The sprayhead of claim 2 , further comprising a button pivotally coupled to the lower body portion and coupled to the movable disc such that actuation of the button causes the movable disc to move radially relative to the outlet disc.

5. The sprayhead of claim 4 , wherein the second direction is a radial direction, and wherein actuation of the button controls the volume of fluid flowing through the sprayhead.

6. The sprayhead of claim 1 , wherein:
the passageway through the movable disc comprises:
a bore fluidly coupled to the fluid inlet and extending from the inlet side at least partially through the movable disc; and
a channel extending radially along the outlet side, the channel having a first end fluidly coupled to the bore and a second end opposite the first end;

when the movable disc moves in the first direction relative to the outlet disc, the channel radially aligns with at least one of the first outlet port, the second outlet port, and the third outlet port;
when the movable disc moves in the second direction relative to the outlet disc, the second end passes over the at least one of the outlet ports such that the channel progressively overlaps the at least one of the outlet ports.

7. The sprayhead of claim 1 , further comprising an adapter, the adapter supporting an aerator fluidly coupled to the first outlet port and defining a second outlet fluidly coupled to the second outlet port;
wherein the cartridge comprises a cartridge bottom supporting the adapter defining a third outlet fluidly coupled to the third outlet port.

8. A sprayhead, comprising:
a body comprising a fluid inlet, a first fluid outlet, a second fluid outlet, and a third fluid outlet;
a first disc comprising a first outlet port coupled to the first fluid outlet, a second outlet port coupled to the second fluid outlet, and a third outlet port coupled to the third fluid outlet;
a second disc slidably coupled to the first disc and movable relative thereto, the second disc located between the fluid inlet and the first disc, wherein the second disc is configured to rotate about an axis of rotation and configured to translate in a radial direction relative to the axis of rotation while the sprayhead is in use;
wherein movement in a first direction of the second disc relative to the first disc fluidly couples the fluid inlet to at least one of the first outlet port, the second outlet port, and the third outlet port, and wherein movement in a second direction of the second disc relative to the first disc controls a volume of fluid flowing from through the sprayhead.

9. The sprayhead of claim 8 , wherein the second disc comprises:
a first side adjacent the first disc;
a second side opposite the first side;
wherein the second disc defines a bore fluidly coupled to the fluid inlet and extending from the second side at least partially through the second disc; and
wherein the second disc defines a channel extending radially along the first side, the channel having a first end fluidly coupled to the bore.

10. The sprayhead of claim 9 , wherein when the second disc moves in the first direction relative to the first disc, the channel radially aligns with at least one of the first outlet port, the second outlet port, and the third outlet port.

11. The sprayhead of claim 9 , wherein the channel includes a second end opposite the first end, and wherein when the second disc moves in the second direction relative to the first disc, the second end passes over the at least one of the outlet ports such that the channel progressively overlaps the at least one of the outlet ports.

12. The sprayhead of claim 11 , wherein when the second disc moves in a direction opposite the second direction relative to the first disc, the second end passes over the at least one of the outlet ports such that an overlap between the channel and the at least one of the outlet ports progressively diminishes.

13. The sprayhead of claim 8 , wherein the first direction is a rotational direction.

14. The sprayhead of claim 8 , wherein the second direction is a radial direction.
