HYDRAULIC STEERING UNIT

The invention relates to a hydraulic steering unit (1) including a housing (3), a spool, a sleeve (12) arranged between spool and housing (3), and a measuring motor (14) having a number of working chambers (15), wherein a first commutation geometry (18) and a second commutation geometry (19) are arranged between the sleeve (12) and the housing (3), wherein the commutation geometries (18, 19) are connected to the working chambers (15) of the measuring motor (14) and the housing includes a first direction port (4), a second direction port (5), a pressure port (6), and a return port (7). The object is to have a good steering behavior. To this end one of the commutation geometries (18) is directly connected to the first direction port (4). 本发明涉及一种液压转向单元(1)，该液压转向单元包括：壳体(3)；阀芯；套筒(12)，其布置在阀芯和壳体(3)之间；以及具有多个工作腔(15)的测量马达(14)，其中，在套筒(12)和壳体(3)之间布置有第一换向几何结构(18)和第二换向几何结构(19)，其中，换向几何结构(18、19)与测量马达(14)的工作腔(15)相连接；并且壳体包括第一方向端口(4)、第二方向端口(5)、压力端口(6)和返回端口(7)。目的在于具有良好的转向性能。为此，一个换向几何结构(18)直接连接到第一方向端口(4)。
