Hydraulic valve for a pivoting motor adjuster having a. a valve housing which has a stepped bore with two operating connectors (A, B) which branch off from it in the form of transverse bores (28, 29), b. a pressure-equalized hollow piston which is arranged such that it can be displaced axially within the bore between a first and a second end position, c. a piston inlet for the axial introduction of a pressure medium into a cavity of the hollow piston, which cavity can be connected to a pressure medium connector, the pressure medium connector being formed by way of a housing inlet of the valve housing, d. a piston outlet which leads out of the cavity of the hollow piston for connecting the pressure medium connector to one of the operating connectors (A, B), e. two tank connectors (TA, TB) for connecting the operating connectors (A, B) to a pressure medium reservoir, f. a tappet for axially adjusting the hollow piston by way of an actuator, g. the hollow piston having, at its end which faces the pressure medium connector, a first piston section with a first, small external diameter, h. in an adjacent manner so as to follow the said first piston section, a second piston section with a second, large external diameter, and i. a third piston section with a third, medium external diameter, it being possible for the three piston sections (39, 40, 41) to be displaced in each case in a housing section (42, 43, 44) of the valve housing in a tolerably sealing manner, j. the hollow piston having, for pressure equalization, in each case one pressure face (A1, A3) on the first piston section and the third piston section, which pressure faces (A1, A3), when the hollow piston is loaded with pressure, can be loaded in each case with an axial force (F1, F3) which points away from the pressure medium connector, which axial forces (F1, F3) act in total as a force (F1,3) on the hollow piston, and a further pressure face which is provided on the second piston section being configured on the hollow piston, which pressure face, as the single pressure face of the hollow piston, can be loaded with an axial force which points towards the pressure medium connector, the forces (F1,3, F2) which act on the hollow piston from both axial directions being of substantially identical magnitude, with the result that the force on the first piston section is substantially compensated for by way of the forces (F2, F3) which prevail between the operating connectors (A, B). a. a valve housing which has a stepped bore with two operating connectors (A, B) which branch off from it in the form of transverse bores (28, 29), b. a pressure-equalized hollow piston which is arranged such that it can be displaced axially within the bore between a first and a second end position, c. a piston inlet for the axial introduction of a pressure medium into a cavity of the hollow piston, which cavity can be connected to a pressure medium connector, the pressure medium connector being formed by way of a housing inlet of the valve housing, d. a piston outlet which leads out of the cavity of the hollow piston for connecting the pressure medium connector to one of the operating connectors (A, B), e. two tank connectors (TA, TB) for connecting the operating connectors (A, B) to a pressure medium reservoir, f. a tappet for axially adjusting the hollow piston by way of an actuator, g. the hollow piston having, at its end which faces the pressure medium connector, a first piston section with a first, small external diameter, h. in an adjacent manner so as to follow the said first piston section, a second piston section with a second, large external diameter, and i. a third piston section with a third, medium external diameter, it being possible for the three piston sections (39, 40, 41) to be displaced in each case in a housing section (42, 43, 44) of the valve housing in a tolerably sealing manner, j. the hollow piston having, for pressure equalization, in each case one pressure face (A1, A3) on the first piston section and the third piston section, which pressure faces (A1, A3), when the hollow piston is loaded with pressure, can be loaded in each case with an axial force (F1, F3) which points away from the pressure medium connector, which axial forces (F1, F3) act in total as a force (F1,3) on the hollow piston, and a further pressure face which is provided on the second piston section being configured on the hollow piston, which pressure face, as the single pressure face of the hollow piston, can be loaded with an axial force which points towards the pressure medium connector, the forces (F1,3, F2) which act on the hollow piston from both axial directions being of substantially identical magnitude, with the result that the force on the first piston section is substantially compensated for by way of the forces (F2, F3) which prevail between the operating connectors (A, B).
