Abstract

A flotation device includes an injector having a flow channel with a variable cross sectional area with respect to the direction of fluid flow through the injector. The injector introduces a mixture of gas and liquid into the device. The injector flow channel has repeated narrowings and widenings in the direction of fluid flow through the injector.
