Abstract
PURPOSE: To decrease an outflow angle as the spool displacement increases in a small range of the spool displacement and prevent a change of flow rate even for a change of load pressure in a large range of the load pressure.
CONSTITUTION: In this flow rate control valve, when displacement (x) of a spool 3 is small, flows (m), (n) affected by wall faces 11a, 12a of internal grooves 11, 12 are more dominant than a flow l along a sloped groove 10 with an outflow angle ϕ larger than an angle α of the sloped groove 10. When the spool displacement (x) increases to not less than a prescribed value, the effect of the flows (m), (n) is eliminated to equalize the outflow angle ϕ to the angle α. While the relation between the spool displacement (x) and an opening area (a), because the internal grooves 11, 12 are provided, is such that a curve of the opening area (a) for the spool displacement (x) is convex to the above in a small range of the spool displacement (x). In this way, an excessive decrease of the spool displacement due to the flow force can be pevented thus the flow rate in a large range of load pressure can be maintained at constant.
