ABSTRACT:
A fluid or detergent mixer comprises a body (2) in which is located a rotatable eductor tube (4) with a venturi throat (17) and a knob (3) to rotate the tube. The mixer has a suction line (5) to draw detergent from the bottom of a detergent container (6) and mix it with the water as it flows and finally through the eductor via a control valve (13) and air gap (14). The eductor tube may have two or more metering orifices (22) which are brought, selectively, into alignment with the detergent suction line (5). For convenience the fluid mixer is supplied to the end user with the detergent container already attached.
