Abstract
Improved unpacking, of the type that are formed by a tubular body, through which a plunger runs before, and that incorporate an elastic and hollow part at one end, which adapts to the pipe to be unblocked; essentially characterized in that the tubular body has two holes, facing and close to one end, operatively dimensioned to give way to cylindrical bodies, the cylindrical bodies being constituted by two joined half-cylinders, each of which emerges laterally to two equal pieces that together constitute the stopper and the guide passage of the piston rod, the rod having a cross section of equal arms, and the piston a circular plate extended inferiorly in a threaded body, through which passes a nut that fixes another circular plate, existing between both plates a peripheral groove by which a ring of elastic material with an outer diameter slightly greater than that of the circular plates is incorporated loosely, of which the lower one presents radial ribs on the inner side of the groove, constituting the spaces between the ribs, of air when the piston sucks.
