Abstract

Pneumatic device for driving diaphragm pumps, characterized in that it comprises, inside the bar that joins the membranes of the suction and impulsion chambers of the pump, an axial conduit divided into two sections that go from the central zone of the bar to the chambers anterior to the membranes of the pump with whose chambers communicate radially, and in whose central zone the bar forms a core of quadrangular section that presents, in turn, independent radial outlets of each of the sections of the axial conduit, arranged in a labyrinth form on two opposite sides of the core, so that the outputs on the right side correspond to the left conduit and vice versa; the outputs of one face are closer to the center than to the other side and a ring, also of quadrangular section, is acting on them, which is capable of moving alternately within the space limited by the situation of two walloons pointing to the ends of the nucleus, to which end said ring is of shorter length than said core; having the face of the ring covering the nearest communication holes with the axial conduit a central connection for flexible tubular intake of pressurized air by connection to an industrial pneumatic conduit, and on the end sides of the same face some notches which leave the alternatively, the holes on one side and the other are discovered, while the one that is covered is facing the intake of air under pressure, causing the filling of the anterior chamber and displacing the corresponding membrane which, in turn, drags to the bar, which produces in this chamber the impelling action of the pump, while in the other the suction action takes place, escaping the air of the latter, and causing with said displacement the change of position of the ring, aided by the action of an elastic pivot coupled between the ring and the closing cover of the housing of the device, with the particularity that the rear face of the ring has an interi ordinarily flat joints that alternately close the corresponding hole or leave it free, depending on the displacement of the ring, to favor the escape of the air already used and the movement of the bar and membranes.
