Abstract
PURPOSE: To flow the controlled given flow to the control flow port and the remaining flow to the excessive flow port, by controlling the oriffice opening area when the plunger is moved with the pressure at the port side of control flow.
CONSTITUTION: The pump port 1 always flows to the ring grooves 9 of the spool 5 via the ring groove 6 formed on the spool 5 and via the path 7 and the concave groove 8 formed on the main body 4. Further, when the pressure of the control flow port 2 is less than the set pressure determined with the control spring 14, the first oriffice 16 only is opened to the oil path groove 15 always connected to the groove 9, and the second oriffice 17 is kept closing. Next, when the pressure at the port 2 is more than the set pressure, the plunger 13 moves left against the spring 14, the second oriffice 17 is opened and the substantial opening area of oriffice is extended.
