<p>A hydraulic valve device, especially in the form of at least one load sensing valve, includes a valve housing (10), a control slide (12) longitudinally movable in the housing and controlling a fluid connection arrangement (14). The fluid connection arrangement includes at least one control pressure line (PST) and at least one supply pressure line (Y). At least for a load sensing connection (LS), a pocket-type channel (18) is arranged between the valve housing (10) and the control slide (12), as well as for a control pressure line (PST) and a supply pressure line (Y). This arrangement enables the available ring channel of the load sensing message chain to be used on axial point of the control slide axle, reducing cost and space.</p> |
