Diverter valve
A diverter valve which is operable to divert a water supply to a spray includes an undiverted through passage for another water supply, such as filtered water.
1. A diverter valve for a water supply, the diverter valve having an undiverted flow path through the diverter valve which is not interrupted by operation of the diverter valve, and comprising a tube having a tube inlet at a tube inlet end and a tube outlet at a tube outlet end and forming the undiverted flow path, wherein a valve member is slidably mounted on the tube, wherein the valve member reciprocates along the outside of the tube, wherein the diverter valve selectively diverts the water supply from an inlet, and between a first outlet and a second outlet.
2. The diverter valve as claimed in claim 1 , wherein the undiverted flow path passes in an axial direction through the diverter valve.
3. The diverter valve as claimed in claim 2 , wherein the flow path lies on a centre axis of the diverter valve.
4. The diverter valve as claimed in claim 1 wherein the valve member has a valve head at one end which cooperates with a surrounding valve seat when the valve member is urged in a first direction, to shut of flow of water in the opposite direction.
5. The diverter valve as claimed in claim 4 , wherein a flow regulator is mounted on the valve member to control the rate of flow of water to a spray.
6. The diverter valve as claimed in claim 1 , wherein an upper end cap is provided at the outlet end of the tube for fluidly connecting the tube with an outlet spout.
7. The diverter valve as claimed in claim 1 , wherein a bottom end cap is provided at the inlet end of the tube for fluidly connecting the tube with a water supply.
8. The diverter valve as claimed in claim 1 , wherein the inlet is perpendicular to an axis of reciprocation of the valve member.
9. The diverter valve as claimed in claim 1 , wherein the first outlet and the second outlet are axially aligned.
10. A water tap comprising a body, valve means controlling at least two water supplies to the body, spout means connected to the body and forming an outlet for the water supplies, spray means connected to the body, and a diverter valve which is operable to divert one of the water supplies to the spray means when the spray means is actuated and substantially prevent flow of the at least one water supply to the spout, wherein the diverter valve includes a tubular member defining a through passage for at least one other of the water supplies, and further comprises a valve member slidably mounted on the tubular member, wherein the valve member reciprocates along the outside of the tube.
11. A water tap comprising a body, valve means controlling a water supply to the body, a spout connected to the body and forming an outlet for the water supply, a spray connected to the body, and a diverter valve which is operable to divert the water supply to the spray when a valve for the spray is actuated and to substantially prevent flow of the one water supply to the spout, wherein the diverter valve includes a tubular member defining a through passage which is not interrupted by the operation of the diverter valve, and the diverter valve comprises a valve member slidably mounted on the tubular member, wherein the valve member reciprocates along the outside of the tube.
12. The water tap as claimed in claim 11 , wherein the water supply comprise hot and cold water.
13. The water tap as claimed in claim 11 , wherein a filtered water supply is provided and the through passage is for the filtered water supply.
14. A diverter valve for a water supply, the diverter valve having an undiverted flow path through the diverter valve which is not interrupted by operation of the diverter valve, and comprising a tube having a tube inlet at a tube inlet end and a tube outlet at a tube outlet end and forming the undiverted flow path, wherein a valve member is slidably mounted on the tube, wherein the valve member reciprocates along the outside of the tube, wherein an inlet is perpendicular to an axis of reciprocation of the valve member.
15. The diverter valve as claimed in claim 14 , wherein the diverter valve selectively diverts the water supply from the inlet, and between a first outlet and a second outlet, and wherein the first outlet and the second outlet are axially aligned.
