In an apparatus for delivering liquid under high pressure, especially for cleaning purposes, with a pump 1, a flow-controlled bypass valve 2 and injector elements 9 for controlling the bypass valve 2 and for sucking up concentrated cleaning fluid, which is to be mixed with carrier liquid from an inlet 6 for the latter, the novelty resides in the fact that the injector elements 9 comprise separate injectors 9a, 9b for the two functions. The risk of aggressive cleaning fluid damaging the control element 10 for the bypass valve 2 is thereby removed or significantly reduced, since the path from the cleaning fluid inlet 7 to the control element 10 runs through both injectors 9a, 9b, whilst in previous arrangements there was a direct path, since only a single common injector was used. <IMAGE>
