Abstract

The present invention concerns to a volumetric pump comprising a couple of gears (1) with parallel rotation axes, wherein said gears cooperate reciprocally inside a casing (15) that communicates both with the suction opening (2) and the outlet opening (3). Said suction opening communicates with said casing (15) through a pipe (4) that is parallel to the axes of the gears (1), while said outlet opening (3) communicates with the same casing (15) through two pipes (6, 7). The axes of said pipes intersect the tangential line to the primitives of the gears (1) in the very tangency point to said primitives. Said pipes terminate in said casing (15) but in opposite positions with respect to the line joining the axes of the gears (1) and they are detected by diverting devices (8). Said devices are directly controlled by pressure increases and decreases in said pipes (6, 7). (Fig. 3)
