Spray heads

A spray head adapted for connection to a supply of fluid, comprising:

• a body to receive the supply of fluid,
• a plurality of conical mixing volumes, in fluid connection with the body and supply of fluid, each conical mixing volume having an outlet, each conical mixing volume including:
• a. at least one first inlet for a flow of fluid into the conical mixing volume at an angle to a conical axis thereof, and
• b. at least one second inlet for a flow of fluid into the conical mixing volume substantially parallel to the conical axis and offset from the conical axis, and
• a valve disposed upstream of the conical mixing volumes, the valve adapted to divide and vary the supply of fluid flow between the at least one first inlet and the at least one second inlet, which in turn varies the output of the fluid from the outlet of the conical mixing volumes,
• wherein the conical axis intersects the outlet.

A spray head adapted for connection to a supply of fluid, comprising:

• a body to receive the supply of fluid,
• a plurality of conical mixing volumes, in fluid connection with the body and supply of fluid, each conical mixing volume having an outlet, each conical mixing volume tapering from a base to the outlet formed by an aperture at a peak of the conical mixing volume and including:
• a. at least one first inlet for a flow of fluid into the conical mixing volume at an angle to a conical axis thereof, and
• b. at least one second inlet disposed at or toward the base for a flow of fluid into the conical mixing volume substantially parallel to the conical axis, and
• a valve disposed upstream of the conical mixing volumes, the valve adapted to divide and vary the supply of fluid flow between the at least one first inlet and the at least one second inlet, which in turn varies the output of the fluid from the outlet of the conical mixing volumes.
