Spray head

A spray head including:

• an inlet for receiving fluid;
• a plurality of nozzles in fluid communication with the inlet, wherein each nozzle of the plurality of nozzles defines a nozzle opening at a downstream end thereof;
• a housing that defines a fluid pathway such that, when in use, fluid enters the housing via the inlet and exits the housing from the nozzle openings;
• a swirl inducer downstream of the inlet and adapted to produce, when in use, a swirled fluid flow, wherein the swirl inducer is in fluid communication with the inlet and disposed between the plurality of nozzle openings and the inlet, and wherein the swirl inducer is configured to produce the swirled fluid flow before the fluid reaches the nozzle openings, by providing or enhancing a rotational speed component of the fluid;
• and
• a back-flow prevention arrangement configured to prevent fluid moving back upstream in the spray head;
• wherein each of the plurality of nozzles is associated with a separate and respective flow chamber, which forms a part of the fluid pathway, wherein the flow chamber extends from each respective nozzle opening and into the housing of the spray head;
• wherein the fluid pathway includes at least one fluid conduit or channel in fluid communication with the inlet, wherein the at least one fluid conduit or channel is configured to direct fluid to each flow chamber, wherein the back-flow prevention arrangement includes a plurality of flow resistance pockets extending in a transverse and upstream direction from its respective fluid conduit or channel;
• wherein the plurality of nozzles are adapted to shape the swirled fluid flow exiting therefrom into a continuous jet of fluid of dome shape.
