• one or more air inlets opening into the mixing chamber from the air intake conduit and one or more liquid inlets opening into the mixing chamber from the liquid intake conduit;
• the or each said liquid inlet entering the mixing chamber by way of a permeable regulator element including a mesh,
• a check valve between the permeable regulator element and the discharge outlet;
• a body component defining the foam chamber and an air conduit jacket component fitting around the body with clearance between the jacket component and the body providing all or part of the air intake conduit;
• and
• wherein the or each said air inlet enters the mixing chamber directly without passing through a permeable regulator element.
