Latest Patents

One of his latest patents is for a horizontal directional drill with a freewheel mode. This innovative drilling machine features a drill string rotational drive unit that connects with and selectively drives the rotation of a drill string. The unit includes a hydraulic motor, and the hydraulic circuit is designed to switch between a drive mode, which applies torque, and a freewheel mode, which disables torque application. The hydraulic circuit consists of a first fluid flow path that connects the hydraulic motor through a rotary ball valve to either the inlet or outlet side of a drive pump, and a second fluid flow path that connects the hydraulic motor through another rotary ball valve to the opposite side of the drive pump. In the first configuration, there is no pressure drop across the rotary ball valves, enhancing the efficiency of the drilling process.
