The gasoline vapor adsorbed completely can import breathing ring cavity 40 by several upper air guide mesh 39, not be adsorbed completely finally
Gasoline vapor diffuses in air；It is discharged as gasoline vapor endlessly passes through air distribution hole 37, stretches and store in gas inner cavity 16
Air pressure gradually become smaller, the airbag 12 that stretches also gradually slowly is shunk in the axial direction, and annular piston 50 can in pressure-controling spring at this time
It is gradually shifted up under 31 elastic reaction, when the air pressure drop in flexible airbag 12 is as low as the threshold value for needing pressure release, annular is living
Plug 50 has been shifted up to all air distribution holes 37 are higher by, and upper piston ring cavity 36.1 is not connected to any one air distribution hole at this time
37, therefore the flexible gas inner cavity 16 that stores is restored to the state with external environs, continues to renew fuel-steam；
When engine start state, engine-cooling system is had been switched on, and 2 temperature of engine gasoline case can decline, and is stretched
The air pressure that contracting stores in gas inner cavity 16 not will increase, and storage gas inner cavity 16 of stretching at this time is in air-tight state, and will not leak fuel oil, start
When machine is run, control solenoid valve 5 is opened, and steam recovery pipe 15 is in unimpeded state at this time, engine when engine operating state
Inlet manifold 4 can automatically generate lasting negative pressure because of intake stroke, and then make to generate negative pressure in steam recovery pipe 15, and then make
Negative pressure is generated in negative pressure ring cavity 22, finally makes to form negative pressure in active carbon filling ring cavity 19, under subnormal ambient, active carbon filling
The gasoline vapor being tightly held by activated carbon in ring cavity 19 can be evaporated again, and external air passes through on several in time at the same time
