Latest Patents
Harper holds a patent for a hydraulic drive system and method of operating a hydraulic drive system. This invention comprises a hydraulic actuator featuring a piston that is reciprocable between two cylinder heads for actuating a machine. The system includes a flow switching device that reverses the direction of hydraulic fluid flow to and from chambers on opposite sides of the piston. The piston halts at the end of each stroke when a shuttle valve opens, allowing hydraulic fluid to flow between the chambers and canceling the differential pressure acting on the piston. A controller is programmed to determine when the piston reaches the end of each stroke based on hydraulic pump speed, hydraulic fluid pressure, or elapsed time. The controller then sends an electronic signal to command the flow switching device to reverse the hydraulic fluid flow.
