Abstract

A control unit (1) for a hydrostatic steering arrangement has two alternatively operable control systems having a common steering member, said control unit having in a housing drill hole (31) a sleeve-shaped inner rotary slide (33), which is connected with an inlet shaft, and a sleeve-shaped outer rotary slide (32), which is connected with a measuring motor (39), both rotary slides being mutually rotatable at a predetermined angle against the force of a spring (40). The first control unit has an interlocking device (41), which connects the two rotary slides (32, 33) unrotatably with each other when the first control system (1) is non-active. Thus, a dead band in the non-active control system disappears, which improves the operation comfort.
