Abstract
The invention relates to a resin injection regulator for a resin injection circuit in a mould for producing a composite part, in particular a turbine engine composite part, characterised in that it comprises at least one vessel which is connected to said circuit and inside of which a movable wall means can be moved in a sealed manner, said movable wall means defining in said vessel a first cavity which forms a container for accumulation of resin and is designed to be connected to at least one part of said circuit, and a second cavity which is designed to be connected to a source of pressurised fluid, said movable wall means being designed to be urged by the pressurised fluid with which the second cavity is supplied in order to exert a pressure on the resin contained in the first cavity by isolating said resin from said fluid.
