録請求の範囲第１項に記載の分流弁。[Claims for Utility Model Registration] 1. A fluid inlet port communicating with a fluid source; and supplying working fluid supplied from the fluid source through the fluid inlet port to a first hydraulic circuit system pipeline where fluid pressure fluctuations are large. a first discharge port for supplying the working fluid supplied from the fluid source through the fluid inflow port to a second hydraulic circuit system pipe line that is required to have small fluctuations in fluid pressure; a spool that moves within the valve chamber to open and close the first and second discharge ports; urging means that biases the spool in a direction in which the spool closes the first discharge port; and the valve chamber. a damper chamber defined by the spool; and a damper hole formed in the spool so as to communicate the damper chamber with the fluid inflow port, the spool closing the first discharge port. When the spool moves in the direction, the fluid in the damper chamber is discharged to the fluid inlet port side through the damper hole to adjust the moving speed of the spool. A flow dividing valve that has a relief passage that communicates with at least one of an inflow port and a first discharge port, and whose other end communicates with the damper chamber. 2 The opening of the relief passage formed in the damper chamber is formed in a position where the spool closes when the spool moves a predetermined distance in the direction of closing the first discharge.Registered as a utility model. A flow dividing valve according to claim 1.
