METHOD AND DEVICE TO CHECK FOR LEAKS IN FUEL VAPOUR RECOVERY SYSTEM STAGE II Russian patent published in 2013 - IPC B60S5/02 B67D7/04 

FIELD: transport.

SUBSTANCE: invention can be used in filling complex for detection of fuel leaks in fuel recovery system. Proposed system comprises underground reservoir and multiple dispensing stations hydraulically communicated with said reservoir. Controller effects tests continuously the vapour recovery system for leaks by sampling said system during breaks in its operation. During said breaks fuel vapour pressure in underground reservoir is measured. Reservoir pressure variation allows determining the system tightness. Invention comprises algorithms of continuous monitoring of leaks in said system and testing the system operation.

EFFECT: higher validity of control.
