Title: Innovations by Roger R. Pili
Introduction
Roger R. Pili is an accomplished inventor based in Madison, WI (US). He has made significant contributions to the field of hydraulic systems, holding a total of 6 patents. His work focuses on innovative designs that enhance the efficiency and functionality of hydraulic pumps and valves.
Latest Patents
One of his latest inventions is the air-driven hydraulic pump. This rotary air motor-driven hydraulic pump features separate pressure and return actuators, along with first and second stage eccentric driven pistons that operate 180 degrees out of phase. The design includes on/off/proportional valves for the actuators and two pressure relief valves, one of which is adjustable from outside the pump. This allows users to set a pressure limit, ensuring optimal performance. Additionally, a bypass valve is incorporated to manage excess flow, while a pressure limiting valve can cut off the air supply at a predetermined output pressure.
Another notable patent is the zero-leak variable rate high-pressure metering valve. This valve consists of a valve element with a closing portion, a metering portion, and a rapid return portion. The design allows for precise flow rate metering based on the overlapping length of the metering portion within the valve bore. The rapid return portion is engineered to facilitate quick fluid return, enhancing the overall efficiency of the system.
