Abstract

New oleo-hydraulic pump, characterized by a housing body with a stepped internal housing that determines two diameters of different sizes, the largest of which is communicated with the outside by means of two lower opposite ducts, which comprise the suction and delivery of the pump, to the once it receives the driving gear, in the form of a bowl with internal carving of circular teeth, which contains the visor of the cover piece and the driven gear in conjunction with the adjustment cap, attached to said visor by means of fixing screws, while this second gear is mounted on its corresponding axis, but displaced with respect to the axis of the first in such a way that they engage only by the lower part, which causes the closing of passage between the aspiration and drive of the assembly, the time that said axis is eccentrically linked to a shaft part that is housed in the cover of the housing, being fixed and grasped the same by means of external knurling in collaboration with an anchoring screw which, however, does not prevent acting on it in turning movement facilitated by two blind holes provided for this purpose, completing the assembly with a graduated scale or nonius, engraved in the part front of the size, which serves as an indicator of the rotation made in the shaft holder, when it is intended to correct a slack or wear, so that a supplement of equal thickness is inserted between the visor and the cap to the mark in the nonius, with whose operation corrector the mismatch produced, is fully compensated.
