Abstract
In a load sensing valve including a proportioning valve (P-valve) and a deceleration sensing valve (G-valve), a compensating device is installed for varying the volume of the fluid sealing chamber of the G-valve in accordance with the magnitude of sealed hydraulic pressure in the fluid sealing chamber when the sealed hydraulic pressure is lower than a predetermined valve to change the pressure controlling characteristic of the proportioning valve.
