Selectable, anti-leak, nozzle-holder

A nozzle device for mounting on a vehicle comprising:

• an annular body having a plurality of radial passages, a plurality of arms each being provided with a spray nozzle, means for radially interengaging said arms about the periphery of said annular body, each in alignment with a radial passage,
• said annular body having an axial opening to receive a plug, said plug having an axial passageway extending longitudinally between opposite ends of the plug and connecting to a radial duct at one end of the plug,
• said duct and annular body arranged for selective alignment of said duct with one of said radial passages,
• said annular body being mounted rotatably with respect to the plug whereby selection of a given nozzle type is effected by angular displacement of said annular body,
• said plug having at its other end an anti-drip means comprising a body at the other end of the core forming in part a dispensing chamber and a diaphragm supported across the dispensing chamber and deflectable to cover at least said axial passageway to stopper it,
• said plug having at its other end means defining an inlet duct integral with the plug and a port extending between the inlet duct and dispensing chamber, said inlet duct communicating with the port and extending transversely to the axial passageway in the plug, said inlet duct having opposite open ends permitting inlet feeding from the holder to an adjacent holder.
