Abstract

Hydraulic pump with oblique plate that can rotate in both directions, of the type that involves a plurality of hollow pistons, parallel to the axis of the pump, driven according to an alternative movement by said oblique platinum, resting each piston against the latter by means of of a plot, making the feeding of each piston by means of a lunula arranged on the saucer, during the passage of each plot on the lunula, characterized by that between the saucer and the plots it is foreseen to interpose a circular support plate in turn placed in rotation thereon, said support plate carrying the piston supply lunula and being able to pivot in such a way that it can be placed on one side or the other of the line with the highest slope of the pan, rotating the bale on the pan through a plurality of pawns arranged on a circle concentric to it and coming out through a circular groove engraved on it. To the rear face of the plate which is limited in its rotation movement by means of a pawn of the plate, whose pawn circulates through that groove in the arc of a circle which is constituted partially by the referred lunula that crosses the thickness of the plate, in such a way that the pawn limits the movement of the plate, either by striking against the end of the lunula or by hitting against the end of the groove, provided that the angular separation between the two extreme positions occupied by said pawn is equal to 180º. Plus the angular variation of delay for the necessary aspiration in the decompression of the pistons at the end of the recoil travel, (Machine-translation by Google Translate, not legally binding)
