Latest Patents
One of his latest inventions is a hydraulic power steering device. This apparatus is designed with a damper valve that is strategically placed within hydraulic oil circuits. It connects an oil passage selector valve in a gearbox with the right and left oil chambers of a power cylinder. The damper valve features a spool valve, with its control oil chamber linked to a hydraulic oil feed passage from a hydraulic pump driven by an internal combustion engine. This design allows for the effective discharge of hydraulic oil. Additionally, the back pressure chamber is connected to a hydraulic oil circulating passage that links the oil passage selector valve with a reservoir tank. The system includes orifices in the connecting oil passages, which facilitate increased opening of the spool valve as the discharge oil pressure from the hydraulic pump rises.
Another significant invention by Wang is a variable capacity type pump. In this design, the inner diameter of the cam ring features a negative slope curve. This curve connects a complete round curve and a negative slope curve, with the end portion of the suction port serving as the starting point. This innovative design enhances the performance of the pump by optimizing the flow between the suction and discharge sections.
