  • Patent number: 12173731
    Abstract: In a pressure compensation valve, a spool portion of a valve body is provided with a throttle passage that constantly communicates with a pump port. A case is provided with supply pressure communication passages to block space between the throttle passage and a load pressure chamber when a poppet portion closes space between the pump port and a cylinder port by biasing force of a load pressure spring, and that, meanwhile, communicate between the throttle passage and the load pressure chamber via a throttle hole when the spool portion moves in an opening direction by a predetermined stroke. A lead-out pressure chamber that presses the poppet portion in a closing direction in a case where an internal pressure increases is provided between the poppet portion and the case, and a lead-out pressure passage that constantly communicates with the cylinder port is connected to the lead-out pressure chamber.
