A method and a device relate to the area of high-pressure vessels and to the construction of a vessel for a liquid which is under pressure in the process of operation of this vessel, and also a method of changing the hydraulic resistance of the liquid at the outlet from the vessel. This vessel can be for example a system of delivering fuel into a combustion chamber, various presses, including screw extruders in which the material which is being extruded is in the form of a non-Newtonian, i.e. viscoelastic liquid. The method consists in that at the outlet from the vessel (1) an additional tank (2) is mounted which is made in the form of a working chamber of variable volume with one or more discharge openings (3), the volume of the indicated additional tank (2) changing depending on the volume of the liquid which is contained in the working chamber of the additional tank, or depending on the change of the physical parameters of the process or according to a set program. The device of the vessel (1) for a pressurized liquid, which vessel is equipped with an additional tank (2) at the outlet from the vessel which has at least one discharge opening (3) is characterized in that the aforementioned additional tank (2) is made in the form of a chamber of variable volume. The tank (2) consists of a stationary element (6) which is connected directly to the vessel (1) for the liquid, an element (7) which can move in the axial direction with one or more discharge openings (3) and which connects these elements of a hollow, predominantly cylindrical element (8) which has a movable connection at least to one of the aforementioned elements (6) and (7) of the tank (2). The automatic or semiautomatic control elements for the volume of the tank (2) are labeled item 9.
