PURPOSE: An automatic constant flow valve is provided to prevent an elastic member from being directly affected by change of fluid state because the elastic member is installed in an outer chamber. CONSTITUTION: An automatic constant flow valve includes a main body(110), a diaphragm(120), an outer cover(131), an actuating unit(140), and an elastic member(150). A fluid inlet is formed in one side of the main body and a fluid outlet is formed in the other side. A chamber is formed between the fluid inlet and the fluid outlet and the fluid inlet and the chamber are connected by a fluid passage. The diaphragm is transformed by pressure differences between the fluid inlet and the fluid outlet. The outer cover is arranged in the exterior of the main body to be identified with the chamber. The actuating unit is arranged inside the chamber so that cross section area of a passage in the fluid outlet side is controlled according to deformation of the diaphragm. The actuating unit penetrates inside an opening and extends to an outer chamber in order to move upward and downward inside the outer chamber.
