Abstract: A fluid regulator has two valve bodies (24, 25) placed opposite and cooperating with two openings (22, 23) for controlling the fluid flow from an inlet chamber to two outlet chambers. A spindle (34) interconnects the valve bodies (24, 25) at a predetermined mutual distance forming a spindle assembly. Each valve body and each opening form a passage (30, 31), the sum of the areas of the two passages being constant, but adjustable by a handle (9). The spindle assembly is freely moveable in the axial direction under the influence of the pressures across the openings acting upon the valve bodies so that the pressure drop times the area of each opening is equal for the two openings, and the fluid flow from the inlet chamber is divided into two fluid flows to the outlet chambers. The fluid regulator is intended to be used in an agricultural sprayer for distribution of a fluid composition to soil to be treated. The agricultural sprayer comprises a tank (2), a pump (6), the fluid regulator, and a plurality of nozzles.
