Abstract: A shower head 10, 10? comprises one or more droplet formation chambers 50, each chamber being supplied with water and pressurised air which divides the water into droplets suspended in the airflow. In one aspect, the geometric parameters of the droplet formation chamber are selected to maintain a balance between primary and secondary droplet formation modes wherein a proportion of the primary droplets formed within the chamber are stripped out of the airflow by impact with the chamber walls and re-entrained as secondary droplets formed by thin film disintegration. In another aspect, the air inlet 40 into the droplet formation chamber is provided with guide surfaces 45 which maintain a parallel axial airflow through the chamber.

Abstract: A shower head (40) has a passageway for a flow of pressurized air from a pressurized air supply, via a Venturi (48) having a convergent portion (46), throat (50) and divergent portion (52), to a shower discharge opening (56), and a passageway (58) for a flow of water from a water supply to a water discharge opening (60) in the Venturi. The Venturi is such that, in use, the general direction of the flow of air is turned through a substantial angle in the Venturi. This folding of the Venturi enables a compact configuration of shower head to be provided.

Abstract: A shower head (10C) has at least one mixing chamber (24) having an air inlet (18) for connection to a supply of pressurized air and a water inlet (22) for connection to a supply of pressurized water so that, in use, the air breaks the water up into droplets in the mixing chamber. The mixing chamber further has at least one outlet (32) so that, in use, the water droplets and air exit the shower head to form a shower of water droplets having a mean trajectory. The or each outlet is arranged so that, in use, at least a substantial proportion of the water droplets exit the shower head so that their individual trajectories on leaving the shower head are offset from the mean trajectory of the shower head and converge towards the mean trajectory of the shower head. This can result in a more uniform distribution of water droplets in the shower pattern. A single annular outlet may be provided, or a plurality of separate outlets.

Abstract: Shower apparatus comprises a shower head (1) for expelling fluid in use, means (2) for connecting the shower head (1) to a water supply (3), a pressurized air supply (4), and guidance means (5) for guiding air flow from the pressurized air supply (4) to the shower head (1).
