Latest Patents

Motohashi's two latest patents showcase his innovative approach to vapor recovery and liquid delivery. The first patent is a **Vapor Recovering Device for Volatile Liquid Dispensing Apparatus**. This device is designed to recover vapor in a vehicle fuel tank by utilizing a hydraulic motor connected to a liquid duct that feeds volatile liquid from a fuel reservoir tank to a gun nozzle. Accompanying this is a pneumatic pump arranged in a vapor duct, which facilitates the transfer of vapor back to the fuel reservoir tank. The ingenious arrangement involves meshing rotors powered by multiplying gearings, ensuring efficient and effective operation.

The second patent, **Liquid Delivery Apparatus**, addresses challenges faced during full tank delivery, particularly after false fuel level detection due to bubbles or splashes. This apparatus includes a spring-biased valve, which is designed to be longitudinally movable. It features a control mechanism that allows the valve to open even when the trigger is activated, ensuring a precise delivery of fuel when the bubbles or splashes are no longer present.
