第２図
第５図Figure 1 is a sectional view of the conventional example, Figure 2 is an overall sectional view showing the embodiment of the present invention, Figures 3 and 4 are sectional views of the spool in the left and right radial direction, and Figure 5 shows the spool slightly rotated. Figures 6 and 7 are cross-sectional views of the spool at the time, and Figures 8 and 8 are cross-sectional views of the spool in the left and right radial direction.
The figure is a cross-sectional view of the spool when the spool rotates further, No. 9
10 are sectional views in the left and right radial directions, FIG. 11 is an enlarged sectional view of the notched groove portion, and FIG. 12 is a radial sectional view. 1 is the valve body, 2 is the spool, 4 and 5 are the load ports, 6 is the inlet port, 7 and 8 are the load pressure ports, and 11 and 12 are the notched grooves.
