Working method:
Under normality (when i.e. interface component powers off), as shown in figure 9, canister of the present invention ventilation magnetic valve is that air-flow is smooth
Lead to state, the iron core 41 in electromagnet assembly 40 can adsorb the permanent magnet 24 in core assembly 20, lead to core assembly 20 and valve
Lid 30 is tightly bonded, and fuel-steam passes freely through the second channel 100b and valve of charcoal tank shell in such fuel evaporation control system
The gas passage of body.
Under interface component is powered, as shown in Figure 10, canister ventilation magnetic valve of the present invention is air-flow closed state, is encouraged
Two coil connectors 42a&42b of magnetic coil 42 are powered, and electromagnetic induction effect electromagnet assembly 40 can become magnet, magnetic pole and valve
24 magnetic pole of permanent magnet in core assembly 20 is to correspondence (magnet peer to repel), and core assembly 20 is by repulsive force to valve body 11
The direction axial passage 11a is mobile, and finally sealed pad 22 is bonded the gas passage of axial rings 11h valve body 11.Fuel evaporation control
A closed system is formd in system processed, and entire vapo(u)rization system is monitored by pressure sensor with the presence or absence of leakage point.
The content being not described in detail in this specification belongs to the prior art well known to professional and technical personnel in the field.
