Abstract

Hydraulic lifting device for toys, applicable to the frame of a means of transport, with dump dump, and characterized essentially by the fact that it is constituted by a hollow, actuating tank of the used fluid, in communication through a narrow channel with an end housing of the box, container of a push button, with spring coupled and slidable along said housing by continuous pressure made on its externally projecting end, by an external lever articulated said box, the inner end of the box being topped off. Said button by a pond gasket, which pumps the fluid coming from the tank into a second adjacent housing and disposed internally along the lower edge of the box, with a channel containing a spring, fixed at its end to the box and the another extensible end capped on an additional ball, constituting a unidirectional valve, which regulates the output of the fluid towards the outer conduit pipe, in communication with a pipe, with an axis of attachment to the frame of the toy, and a sliding piston in its interior and projection proportionally to the pumping carried out, originating the lifting of the tipper, articulated to the frame, to a height suitable for unloading, the box having a filling mouth on the top, closed by a screw that passes through it and whose adjustable end is threaded in a lower blocking cavity, in communication, through a narrow channel, with the pipeline, originating by external manipulation of the screw, the unlocking of its threaded end and the consequent entrance of the existing fluid under pressure in said pipe, with the plunger, which is housed in the pipe, descending, and with it the dump truck adopting a horizontal position on said pipe.
