Latest Patents

Among his latest inventions, Richard introduced a fluid control system for work vehicles that encompasses a variable displacement pump with a load system control, designed to operate in an open center mode. This system includes a pump control capable of transitioning between two arrangements. It utilizes a first load sensor pressure tied to the pump and an actuator return pressure from the actuator, providing selective pump control pressure for optimal performance. Notably, the system operates in a standby mode where the pump functions in a minimized displacement condition, with a different minimized displacement condition in stall mode.

Another significant patent is his development of an open center hydraulic system, which also features a variable displacement pump. This design focuses on maintaining reduced fluid flow based on a predetermined fluid pressure differential between the outlet and its sensing port. The system efficiently uses fluid circuits that serve as signal lines and allows for reduced fluid flow through the pump outlet based on induced fluid pressure reductions from controlled pressure devices.
