The fluid feeder consists of first and second housings (1,13) with a jet (6) between them, joined together by two assembly sections (11, 15), one of which has a recess (14) to hold the jet (6). The jet is fitted in place before the two housings are assembled and its position regulated; the housings are then fixed together so that they cannot be separated and the jet cannot be adjusted. The assembly sections of the two housings comprise an annular collar (11) on the first housing (1) and a recess (15) of the same diameter, except for an assembly clearance, on the second housing (13). They are fixed together permanently on assembly by a film of adhesive.
