Abstract: A system and method for automatically adjusting an ORVR-compatible Stage II vapor recovery system to maintain the air-to-liquid (A/L) ratio within desired tolerances or limits to meet regulatory and/or other requirements. An air flow sensor (AFS) or vapor flow meter measures the amount of recovered vapor for a dispensing point to calculate the recovery efficiency of the system in the form of the A/L ratio. Volume or flow rate measurements can be used. ORVR fueling transactions are either minimized or excluded from the A/L ratio, so that the A/L ratio is not artificially lowered due to a blocked or altered recovery. The A/L ratio is then compared to a desired or nominal A/L ratio. Adjustments to the recovery system are made within prescribed safety tolerances if the A/L ratio differs from the desired ratio.

Abstract: This invention provides a fuel tank venting system for regulating the discharge of fuel vapors and of liquid fuel from a fuel tank. The fuel tank venting system includes fuel vapor vent tubes that are fully enclosed within the system and exit the fuel tank at a common location. Because the fuel vapor vent tubes are fully enclosed within the system, vent valves are not required at each vent point and permeation resistant tubing is not required. In this fuel tank venting system fuel is prevented from reaching the fuel vapor recovery canister under normal operating conditions and the fuel filler pipe serves as a liquid/vapor discriminator. In another embodiment the vent vapor tube does not extend beyond the highest fuel level in the fuel filler pipe because the fuel filler pipe pressure is lower than the fuel tank pressure due to the fuel filler pipe connectivity to the canister.

Abstract: Method of charging dynamic-pressure bearing device with lubricating fluid. Preparatorily, lubricating fluid is put into a vacuum chamber and the chamber is vacuum-evacuated to subject the lubricating fluid to a degassing process.
