Abstract:
Modular directional valve with two or more crossing elements (E 1  . . . En) able, acting only on the entry side, to manage a variable displacement pump (PA) of the load sensing type. In particular, this management allows in a single drive, unlike the conventional crossing distributors, to make the flow rate to the utility independent of the load and allows setting a maximum flow rate at the end of the stroke; in multiple drives, it ensures that the sum of the required flow rates is independent of the loads. A compensated flow rate regulator is placed in the entry side so as to act only on the bypass line LC upstream of the first element (E 1  . . . En) while a proportional choke is placed on the load line consisting of a 2-way 2-position tray.

Claim (Index 1):
Modular directional valve device, with one or more elements or sections (E 1 , E 2 , . . . En) and for the management of a variable displacement pump LS (PA); each element (E 1 , E 2 , . . . En) including spools (C 1 , C 2 , . . . Cn) configured to control the drive to relative utilities (A 1 , B 1 , A 2 , B 2 , . . . An, Bn); the directional valve device arranged for the connection to the pump (PA) by means of a supply line (P 1 ), which is divided into at least two channels, of which:\n a. A bypass line (LC) which, with the spools (C 1 , C 2 , . . . Cn) in central position, crosses all the elements (E 1 , E 2 , . . . En) and then connects to tank T through an independent connection (C), b. A load line which, with spools C 1  . . . Cn in central position, is a closed line, said valve device comprising, on the bypass line LC only and upstream of the first element (E 1 ), a flow rate regulator group comprising at least one piloted spool and a choke; a control signal (P) connected to said flow rate regulator group acting on a proportional variable choke along said supply line (P 1 ) or along said load line; a signal (LS) along said load line downstream of said choke reaches the pump (PA).
