Abstract

PURPOSE: To enable the flow quantity to be controlled gradually by means of setting up the third orifice between the branched path to the rear direction of the second orifice and the flow cut path, in a branched flow control spool which opens and closes by the force of the differential pressure of the front and the rear of orifice.
CONSTITUTION: When the differential pressure of the front and the rear of an orifice 4 becomes larger than the spring force of a spring 12 by means of flowing in the flow quantity proportioned to the rotation number of an engine from an entrance path 2, and of reaching at the set flow quantity, a spool 7 connects a branched path 5 to an exhaust path 6 by means of moving to the left. When the flow quantity from the entrance path 2 becomes larger, the flow quantity passing through the second orifice 13 is increased by the extent, and when the pressure lowering of the second orifice and the pressure lowering of the orifice 4 become equal, the flow quantity passing through the third orifice 15 becomes null. When the flow quantity is further increased, the counter current from a flow out path 3 to the branched path 3 is generated, and one part of control flow quantity from the flow out path 5 is discharged, and the curve as shown in the drawing is obtained.
