Definitions
- the present invention relates to an electromagnetic valve provided with a guard integrally.
- Gasoline transpiration gas generated in a fuel tank of an automobile is captured by a canister, and the purified air is released to the atmosphere.
- the gasoline component captured by the canister is taken into the internal combustion engine by the negative pressure generated in the intake pipe when the engine is operating.
- the amount of gasoline vaporized gas taken into the internal combustion engine is controlled by a solenoid valve (hereinafter referred to as a purge solenoid valve).
- vent passage of the purge solenoid valve and the piping of the intake system are generally connected by a hose, but recently, due to the reduction in the number of piping, (1) fuel leakage from the connecting portion For the purpose of reducing this and (2) reducing pipe connection man-hours, the form of direct attachment to the intake pipes of throttle bodies and intake folds by inserting an O-ring port is becoming mainstream.
- the purge solenoid valve controls the amount of gasoline vaporized gas, even if a large force is applied due to a vehicle collision or the like, the passage portion (portion constituting the valve) is easily damaged. Therefore, it is necessary to consider the mounting location and the mounting form. In other words, an optimum test location and configuration of the purge solenoid valve can be determined by conducting a collision test or the like.
