Abstract
Fluid control device (1), in particular as part of a hydraulic steering unit, the fluid control device (1) having a housing (2) with a supply connection arrangement, an outer slide (4) rotatably arranged in a bore in the housing (2), an outer slide (4) rotatably arranged inner slide (3) and a measuring motor, the measuring motor having a large number of working chambers, each working chamber being connected to the bore via a housing geometry (5), the outer slide (4) having a commutation geometry (7) which together with a housing geometry (5) controls a flow of hydraulic fluid into and out of the working chambers, the commutation geometry (7) having a first division with a first division angle, which is the width of the first division in the circumferential direction, and the inner slide ( 3) has an inner slide geometry (14) which, together with a valve geometry (10, 1st 1) of the outer slide (4) controls a flow of hydraulic fluid between the supply connection arrangement and the commutation geometry (7), characterized in that the valve geometry (10, 11) has a second division with a second division angle, which differs from the first division angle differs, and the commutation geometry (7) is designed as a surface structure on the radial surface of the outer slide (4).
