摘要： PROBLEM TO BE SOLVED: To control a communication path for preventing an abrupt speed reduction by applying a part of the oil on the working side to a traveling side, into a desired state (open state or closed state) depending on situations at compound operation in which traveling operation is simultaneously performed with working operation.
SOLUTION: A communication path 35 and a control valve 36 that opens/closes it are provided in a travel linear motion valve 32. At compound operation, working pressure and traveling pressure are taken in as both-side pilot pressure. So the communication path 35 is closed without condition at travel minute operation which shows a small travel operation amount, the communication path 35 is opened when the working pressure is higher than the traveling pressure at travel major operation which shows a large amount of traveling operation, and the communication path 35 is closed when the working pressure is lower than the traveling pressure.
