Abstract

Improved fluid dosing device, comprising a housing with a hollow interior; first and second inputs to said hollow interior for a first and a second fluid respectively; a fluid outlet of said hollow interior; a first pumping means within said hollow interior and displaceable under fluid pressure between the second inlet and the fluid outlet from an "inlet" position to an "outlet" position, to determine the expulsion of the first and second fluid mixed through of the aforementioned exit; drive means that tend to retain or reset the first pump means in the "entry" position in practice; a conduit that communicates between the second inlet and the outlet for fluid; closure means adapted to close said conduit in said "entry" position and also during the displacement of the first pumping means, under fluid pressure, from the "entry" to the "exit" position and to open such a conduit in the "outlet" position and also during the movement of the first pump means from the "out" position to the "inlet" position; and a second pumping means actuated as the first pumping means moves to cause the entry of a predetermined amount of the first fluid into said hollow interior through the first fluid inlet in each cycle of the first pumping means.
