CONNECTING BODY, FITTINGS, HYDRAULIC SYSTEM FOR FLUID PASSAGE BETWEEN TWO HYDRAULIC CIRCUITS, APPROPRIATE INSTALLATION METHOD Russian patent published in 2021 - IPC F16L25/02 F16L15/04 F16L55/00 

FIELD: hydraulic systems.

SUBSTANCE: invention can be used in hydraulic systems, in particular for connecting two hydraulic circuits. Central body (3) for a hydraulic system (1) for a liquid, comprising a housing (32) having a first tubular end (33) for connecting an inlet hydraulic circuit (2) containing a first fitting (20) and a second tubular end (34) for connecting the outlet hydraulic circuit (4) containing the second fitting (40), while the said central body (3) contains a channel (35) passing through the housing (32) for passing the fluid coming from the input hydraulic circuit (2.4 ), into the output hydraulic circuit (2,4), while the said housing (32) is made of an electrically insulating material, while the central body (3) contains a printed circuit having controlled electrical properties in order to conduct part of the electric charges passing between the input hydraulic circuit (2) and outgoing hydraulic circuit (4).

EFFECT: invention makes it possible to ensure the mechanical strength and tightness of the connection, as well as to ensure the dissipation of currents arising or applied to the hydraulic circuit.
