Abstract

Improved hydraulic circuit, characterized in that for the actuation of three pairs of hydraulic elements such as telescopic cylinders, others of double effect and some support jacks, they start from the head and rear area of each pair of elements, each of which lines are directed to a distributor valve with three possible maneuvering positions, one of which communicates at the outlet of the pump with the general tank, while in the other two it interrupts said communication, establishing it, in both cases and they are the appropriate investment, between the outlet of the pump and one of the lines, as well as between the other line and the general tank; while on the other hand between the lines corresponding to the support jacks and the double-acting cylinders are crossed piloted valves, of which the latter allow the return of the fluid, while those of the jacks prevent possible leaks and intercommunications between the data lines, all in a way that allows the activation of each pair of elements with complete independence with respect to the performance of the others.
