Patent ID: 7270155

Claim:
A gasoline vapor recycling system for gasoline tank, comprising: a route control valve installed on a breathing valve piping extended from a gasoline tank; a discharge processing apparatus connecting to the route control valve; and a gasoline return pipe connecting to the discharge processing apparatus and being extended to the gasoline tank through the breathing valve piping, wherein the discharge processing apparatus further includes: a sensor; a control element connecting to the sensor; a compression unit having an input end connecting to the route control valve; and a processing unit connecting to an output end of the compression unit and the breathing valve piping via the gasoline return pipe and having a rear end connecting to a vapor discharge pipe, wherein the discharge processing apparatus further includes a gasoline vapor reclaiming pipe connecting to a gasoline tanker, the discharge processing apparatus being configured to reclaim gasoline vapor by compressing the vapor to substantially prevent the vapor from flowing back to the tanker.
