Abstract
An improved diaphragm hydraulic pump, characterized in that it comprises, inside a pump body, an intake chamber and a circulation chamber and a fluid circulation conduit, said chambers being in communication through an orifice sealed respectively with a valve. Admission and a circulation valve with the same main chamber in which a diaphragm driven by known means, moves alternately in one direction, and then in the opposite direction so as to vary the useful volume of the chamber and alternately causes the opening and closing of the inlet valve and vice versa the closing and opening of the circulation valve said pump in its circulation chamber is equipped with a low pressure of this chamber in the direction of the intake chamber.
