Latest Patents
One of his latest patents is titled "Load check with mechanical venting means." This invention describes a hydraulic motor and control system that includes a pump for delivering fluid to a control valve. The control valve features a Float position that connects the motor's first end to a sump, a First position for applying fluid from the pump to power the motor in one direction, and a Second position that allows the motor to move in the opposite direction. A conduit connects the control valve to the sump, and a check valve is included in the flow path to facilitate fluid flow towards the motor's first end while blocking reverse flow. Additionally, a mechanism is provided to open the check valve for reverse flow when the control valve is in the Float position or the Second position.
Another significant patent is the "Load check valve cylinder mounted." This invention also involves a hydraulic motor and control system, comprising a pump that delivers fluid to a control valve. Similar to the previous patent, the control valve has a Float position connecting the motor to the sump, a First position for powering the motor in one direction, and a Second position for the opposite direction. The system includes a check valve that allows flow towards the motor's first end and blocks reverse flow, with a mechanism to permit reverse flow responsive to the control valve's operation.
