Latest Patents

Hachisuka holds a patent for a pressure compensation valve. This valve features a spool portion of a valve body equipped with a throttle passage that maintains constant communication with a pump port. The design includes a case with supply pressure communication passages that block the space between the throttle passage and a load pressure chamber when a poppet portion closes the space between the pump port and a cylinder port. The valve operates effectively by allowing communication 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. Additionally, a lead-out pressure chamber is provided to press the poppet portion in a closing direction when internal pressure increases.
