Abstract
A compensator spool of a load sensing valve device has a pressure chamber, a compensator throttle portion, a pressure introduction chamber, a pressure introduction port, a maximum load pressure introduction chamber, and a selector valve. A groove is formed around the pressure introduction port, and a groove moves relatively to a passage communicating with an actuator so as to reduce an area of an opening of the pressure introduction port when the compensator spool moves.
