Hydraulic control-valve unit for controlling a hydraulic working load, having - multiple hydraulic ports in the form of -- at least one entry port for hydraulic connection to a pump, -- at least one working port for hydraulic connection of the working load, and -- at least one return port , which can be connected to a hydraulic tank, - a control slide , which can be transferred into different working positions in an axial direction and serves for controlling hydraulic flow between the hydraulic ports , and - a slide housing , which surrounds the control slide , wherein - the control slide has at least one control segment which is delimited in an axial direction by a control edge and which interacts with an axial housing segment of the slide housing for the purpose of controlling a flow cross section (78, 80, 80-1, 80-2, 80-3, 82-2) for hydraulic flow at this control segment , - the control slide can be driven in rotation in a direction of rotation about an axis of rotation , and - the control edge of at least one control segment and/or the housing segment which interacts with this control segment are/is formed in such a way that the flow cross section (80, 80-1, 80-2, 80-3, 82-2) for hydraulic flow at this control segment varies in size according to different rotational positions of the control slide , wherein the control edge has, sectionally, in a direction of rotation - at least one axially outer edge section , and - at least one axially inner edge section , which is axially inwardly offset relative to the axially outer edge section , characterized in that the axially inner edge section extends at least in part at an angle of greater than 0° and less than 90° relative to the direction of rotation along the direction of rotation . - multiple hydraulic ports in the form of -- at least one entry port for hydraulic connection to a pump, -- at least one working port for hydraulic connection of the working load, and -- at least one return port , which can be connected to a hydraulic tank, -- at least one entry port for hydraulic connection to a pump, -- at least one working port for hydraulic connection of the working load, and -- at least one return port , which can be connected to a hydraulic tank, - a control slide , which can be transferred into different working positions in an axial direction and serves for controlling hydraulic flow between the hydraulic ports , and - a slide housing , which surrounds the control slide , - the control slide has at least one control segment which is delimited in an axial direction by a control edge and which interacts with an axial housing segment of the slide housing for the purpose of controlling a flow cross section (78, 80, 80-1, 80-2, 80-3, 82-2) for hydraulic flow at this control segment , - the control slide can be driven in rotation in a direction of rotation about an axis of rotation , and - the control edge of at least one control segment and/or the housing segment which interacts with this control segment are/is formed in such a way that the flow cross section (80, 80-1, 80-2, 80-3, 82-2) for hydraulic flow at this control segment varies in size according to different rotational positions of the control slide , wherein the control edge has, sectionally, in a direction of rotation - at least one axially outer edge section , and - at least one axially inner edge section , which is axially inwardly offset relative to the axially outer edge section , characterized in that the axially inner edge section extends at least in part at an angle of greater than 0° and less than 90° relative to the direction of rotation along the direction of rotation . <EOS>
