ABSTRACT:
A venturi-type ejector for delivering cleaning liquid to an article to be cleaned and having cold and hot liquid inlets; a high pressure pump for delivering cold liquid to the cold liquid inlet; a boiler for heating liquid and having an outlet for connection to the hot liquid inlet; and a low pressure pump for delivering liquid to the boiler. A pair of motors are connected each to a different pump and are controlled to cause cold or hot fluids to be delivered to the ejector for ejection therefrom separately or together, selectively. Control elements are included for controlling operation of the boiler responsive to flow of liquid to the boiler and to temperature of fluid discharged from the boiler.
