Latest Patents

John B Keir holds a patent for a directional valve assembly used in hydraulic power systems. This invention is particularly applicable to fork lift trucks and features a plurality of sliding spool directional valves along with a balanced relief valve. The design includes a load-holding check valve of special design, which allows for controlled lowering of loads. Additionally, the assembly incorporates mechanisms to prevent interflow between valve spools when multiple spools are shifted simultaneously. This is achieved through a system of restrictors, check valves, and passages, enabling the main relief valve to act as a pressure compensator responsive to the smallest load's pressure requirements. He has 1 patent to his name.
