Latest Patents
One of his latest inventions is an 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 motor drives these pistons through a gear reduction unit. The pump is equipped with on/off/proportional valves for the pressure and return actuators, and it includes two pressure relief valves, one of which is adjustable from outside the pump. This allows users to set a pressure limit for the pump. When the output pressure exceeds a certain limit, a bypass valve redirects excess flow to precharge the second stage compression chamber from the first stage piston to an elastic reservoir. Additionally, a pressure limiting valve can be utilized to cut off the air supply to the pump at the desired output pressure, ensuring the pump stalls at a specific output pressure.
