Abstract
A fluid controller (1), in particular as part of a hydraulic steering unit, is described. The controller (1) comprises a housing (2) with a supply port arrangement, a sleeve (4) rotatably arranged in a bore of the housing (2), a spool (3) rotatably arranged in the sleeve (4), and a measuring motor, wherein the measuring motor comprises a plurality of working chambers, each working chamber being connected to the bore, wherein the sleeve (4) comprises a commutation geometry (7) with a first partition and controlling, together with a housing geometry (5) of the housing (2), a flow of hydraulic fluid into and out of the working chambers, and the spool (3) comprises a spool geometry (14) controlling, together with a valve geometry (10, 11) of the sleeve (4), a flow of hydraulic fluid between the supply port arrangement and the commutation geometry. Such a fluid controller should have stable control performance. To this end, the valve geometry (10, 11) comprises a second partition different from the first partition.
