Disclosed is a nozzle for connection to a pressurised water supply comprising; a body with a channel therethrough, the channel having an inlet and an outlet; a downstream 5 conical deflector positioned at or near the outlet, having a width equal to or greater than the width of the outlet; and an upstream conical deflector attached to the body at the outlet, having a width equal to or greater than the width of the downstream conical deflector; wherein the upstream and downstream conical deflectors define a fluid pathway for water passing through the nozzle. There is also disclosed a nozzle for connection to a pressurised water supply comprising; a nozzle for connection to a pressurised water supply comprising a body with a channel therethrough, the channel having an inlet and an outlet, and a downstream conical deflector positioned at or near the outlet, wherein the 15 downstream conical deflector has a conical angle greater than 160 degrees. There is also disclosed a nozzle for connection to a pressurised water supply comprising a body with a channel therethrough, the channel having an inlet and an outlet, and a downstream conical deflector positioned at or near the outlet, wherein 20 the body further comprises an access port in communication with the channel suitable for the introduction of a pressurised fluid. |
