Abstract

Hydraulic piston that is characterized to be essentially constituted by a chamber or cylinder in which interior is moving a piston or piston properly said, of less diameter and with two extreme zones of adjustment, through the corresponding togets of hermeticity, on the walls of the cylinder cited, determining a central chamber of liquid output, in communication with the exterior of that cylinder, having the mentioned piston one of its extreme free faces, and starting from the other one a connectable vástago to the point of application of the force, which determines a difference of surface of application of the pressure between the two sides, with one of the end of the cylinder of a single entry of driving liquid, whereas the piston is through four ways: one formed by an axial drill in the one that moves a sliding slider of a valve of two positions, with extreme shutters of alternative closure in the seat seats mentioned duct, situated unemploying in minor cameras trails formed in the extreme piston faces; other two situated before the slider and formed by steps that put in communication the resulting enclosures between the extremes of the cylinder and the two extreme faces of the piston, in which they disembose those steps, which are interconnected through the axial drill in the that the valve of sliding is moved, and a fourth travel formed by a radial step that part of the slider's duct, through behind thereof, and unemployed in a chamber of liquid output, staying arrangements being stops for performance on the extremes of the slider with views of the automatic inversion of the piston movement.
