Abstract
A bubble generating device consisting of two tube assemblies presenting a substantially linear support portion leading into a second portion of generally U-shape. In operation liquid is passed through the annular space between the two assemblies and air or some other gas is passed down the inner of the two assemblies. In one of the embodiments described, only one tube assembly is present. This latter embodiment can be used to provide bubbles in liquid flows, gas or coloured liquid being passed through the device in such cases.
Claims8
A device for generating bubbles in a direction of fluid flow, the device comprising:
- a support portion having an inlet adapted to be supplied from a source of material used in forming bubbles and having at at least one end thereof a substantially linear axis;
- a curved portion joined to said one end of the support portion, said curved portion, with increasing distance from the support portion, bending away from and then back towards an extension of said axis from the support portion, said curved portion being bent away from the support portion in a direction opposite that of the fluid flow;
- and
- at least one passage within the support and curved portions, said passage extending from the inlet of said support portion to an outlet port from the curved portion.
