出ポートと連通ずる関係にした油圧分配装置。A first inflow port that communicates with one of the two pumps, a second inflow port that communicates with the other pump, a first outflow port that communicates with a power steering circuit, etc., and a second inflow port that communicates with a work equipment circuit, etc. A spool is slidably installed inside the valve body which has an outflow port and a tank port leading to the tank, and this spool has the first
An oil hole is formed that communicates with the inflow port at all times, and the oil hole is opened to the first outflow boat side through a control orifice, while when the spool is in the original position, the second inflow port The first inflow port also communicates with the tank port, and when the differential pressure before and after the orifice increases and the spool moves a predetermined range from the original position, the first inflow port also communicates with the tank port. A hydraulic distribution device in which communication between the second inflow port and the oil passage hole is cut off, and communication with the second outflow port is established.
