FIELD OF THE INVENTION [0001] The present invention relates to a fluid measurement/division device and process. BACKGROUND OF THE INVENTION [0002] In particular, the device and process of the present invention are usable to divide a fluid flow rate, for example to obtain from an inlet flow two or more outlet flows of equal flow rate, with possible measurement of the flow rate. If only one flow is obtained at the device outlet, the device is used (and operates) as a flow rate measurement device, i.e. it exactly measures the delivered flow rate without effecting any flow rate division. DISCUSSION OF THE RELATED ART [0003] Devices of the indicated type are currently formed with at least three cylinders, in each of which a piston is slidably inserted. [0004] Each piston is provided with two reduced diameter regions which define two distribution chambers inside the cylinder. Each cylinder also defines two pumping chambers at its ends. [0005] The three cylinders are connected together by a plurality of conduits, such that the conduits alternately connect together one or other of the chambers defined between each cylinder and the respective piston. [0006] During operation of the traditional device, each of the pistons is in a different operating stage. [0007] In particular, while a first piston is in a dosing stage (and dispenses a predetermined quantity of fluid contained in a pumping chamber, forcing it to leave the device), a second piston is in a piloting stage (and causes the fluid to operate the dosing piston). [0008] Finally a third piston is in a neutral stage, in which it does not act on the fluid (delivering it to the outside) and is not operated by the fluid; during this stage the piston contained in the cylinder in the neutral stage moves from the piloting position to the dosing position; if this stage were not present, the device would lock because the liquid would not be able to continuously operate the pistons such that they alternate their function by passing from the piloting stage to the dosing stage. [0009] However, the described devices of traditional type are large and heavy because of the minimum number of cylinder/piston pairs required for their operation; in this respect, at least three cylinder/piston pairs are required, each of which effects one of the described stages during operation, while the other cylinder/piston pairs effect the others. [0010] The traditional devices are also costly to construct because of the large number of components required. SUMMARY OF THE INVENTION [0011] The technical aim of the present invention is therefore to provide a fluid measurement/division device and process by which the stated technical drawbacks of the known art are eliminated. [0012] Within the scope of this technical aim, an object of the invention is to provide a device of small size and reduced weight; this advantageously enables devices to be constructed which can be handled and installed easily, even in difficultly accessible or narrow positions. [0013] Another object of the invention is to provide a device and process which are economical to implement, in particular compared with traditional devices. [0014] The technical aim, together with these and other objects are attained according to the present invention by a fluid measurement/division device and process in accordance with the accompanying claims. [0015] Advantageously, the device and process of the invention are also usable when the fluid which they are required to handle operates at high or very high pressure (up to and beyond 2000 bar). BRIEF DESCRIPTION OF THE DRAWINGS [0016] Further characteristics and advantages of the invention will be more apparent from the ensuing description of a preferred but non-exclusive embodiment of the fluid measurement/division device and process according to the invention, illustrated by way of non-limiting example in the accompanying drawings, in which: [0017] FIGS. 1-4 show a schematic view of the device in four different successive operating stages; [0018] FIG. 5 shows a schematic view of a part of an end of a cylinder and of a piston slidable therein, in an embodiment of the device particularly suitable for use with devices operating at high pressure; [0019] FIG. 6 shows a schematic upper view of the device of the invention in a different embodiment; Continue reading about Fluid measurement/division device and process...
