HYDRAULIC FLOW RATE DIVIDER-ADDER

摘要

The invention relates to a hydraulic flow rate divider-adder which equally divides a supplied flow rate or may accumulate the two flow rates, when a fluid is circulated in an opposite direction, meant for the hydraulic installations for driving some synchronized movement mechanisms. According to the invention, the divider-adder comprises a tubular housing (1) wherein there is located a rotor (2) supported on a tubular axle (3) containing an odd number of axial pistons (4), each fixed on a cylindrical rod (5) which may glide between two identical guiding bushings (6.1 and 6.2) forming three compression chambers ( a, b and c), the first two having an equal volume and the other having a volume equal to the added volume of the other two compression chambers, which rests on an inclined disk (7), wherein an outlet lid (8) is pressed, by means of a cylindrical pin (9), while the rotor (2) is closed frontally with two distribution lids (10) having two rows of distribution holes (11) and a single row of holes in permanent contact with an inlet lid (12), in order to divide precisely a flow rate into two equal flow rates, on a direction of flow, or add the two flow rates for the reverse circulation direction as a consequence of the rotation of the rotor (2).
