A device for the administration or dosing of an injectable product comprising a container preloaded with the injectable product and an injection port, and a control valve for controlling the outlet flow rate and pressure arranged between the injectable product and the injection port, the valve comprising limiting means for limiting the injectable product outlet flow rate, which limit the flow rate to a pre-established maximum value when the pressure increases up to a predetermined value, which in turn comprise at least one passage opening for the passage of the injectable product which can gradually be blocked by blocking means, the device for the administration or dosing of an injectable product characterized in that - the control valve is placed inside the container, in that - the control valve comprises a cylindrical-shaped valve body in which the opening is arranged, and an opening for the passage of the injectable product towards the injection port, - and in that the blocking means for blocking the opening comprise - a prolongation towards the inside of the container in the direction opposite the injection port to which there is coupled a tube made of an elastic material with an inlet opening for the inlet of the injectable product, the tube being deformed by the effect of the pressure of the injectable liquid, reducing the dimensions of said tube upon increasing the pressure, and - an elastic flap arranged in the passage opening - which moves to open the passage opening by the effect of the pressure of the injectable product, - and which closes the passage opening in the absence of pressure. - the control valve is placed inside the container, in that - the control valve comprises a cylindrical-shaped valve body in which the opening is arranged, and an opening for the passage of the injectable product towards the injection port, - and in that the blocking means for blocking the opening comprise - a prolongation towards the inside of the container in the direction opposite the injection port to which there is coupled a tube made of an elastic material with an inlet opening for the inlet of the injectable product, the tube being deformed by the effect of the pressure of the injectable liquid, reducing the dimensions of said tube upon increasing the pressure, and - an elastic flap arranged in the passage opening - which moves to open the passage opening by the effect of the pressure of the injectable product, - and which closes the passage opening in the absence of pressure. - a prolongation towards the inside of the container in the direction opposite the injection port to which there is coupled a tube made of an elastic material with an inlet opening for the inlet of the injectable product, the tube being deformed by the effect of the pressure of the injectable liquid, reducing the dimensions of said tube upon increasing the pressure, and - an elastic flap arranged in the passage opening - which moves to open the passage opening by the effect of the pressure of the injectable product, - and which closes the passage opening in the absence of pressure. - which moves to open the passage opening by the effect of the pressure of the injectable product, - and which closes the passage opening in the absence of pressure.
