Latest Patents

One of his latest patents is the "Hydrostatic Load Sense Steering System." This system is designed to control fluid flow from a source to a steering motor and auxiliary motors. It features a priority valve with a housing that includes an inlet port, a priority flow outlet port, an auxiliary flow outlet port, and a pilot port. The priority valve is equipped with a biasing spring that urges the valve spool toward a position that directs all flow from the inlet port to the priority port. The system also includes a steering controller that communicates with a load sense cavity and a neutral vent orifice, allowing for efficient fluid management during steering maneuvers.

Another significant patent by LaHue is the "Hybrid Load-Sense Vehicle Hydrostatic Steering System." This system utilizes fluid flow from a source to enable steering of the vehicle through a hydrostatic steering controller. The controller comprises a metering unit and a control valve that responds to steering efforts. It establishes a main flow control orifice and directs metered fluid to a steering motor. The design ensures that the system can quickly respond to high demand steering maneuvers by developing hydraulic biasing forces on the components of the fluid actuator.
