ABSTRACT:
The present invention relates to a solenoid valve fixing structure. In an apparatus for suppressing evaporated fuel gas emission, of the prior art, the solenoid valve is fixed to a frame of a vehicle independently from the fixing of a check valve or an air filter. Hence, there are drawbacks, for example, that the number of the fabrication elements is large, and the fabrication performance is small.
The present invention propose a solenoid valve fixing structure constructed as a module comprised of a solenoid valve, a check valve and an air filter. Namely a solenoid valve 10 and a check valve 8 are fixed onto a cover 3 of an air filter 1. The number of the fabrication elements can be reduced. The size of the apparatus can be made small, by using the module.
In an embodiment, a nipple (11a) of the solenoid valve (10) is inserted through an O-ring (13) into an insertion hole (3a) disposed in the cover (2), and the solenoid valve 10 is fixed to the cover (2) of the air filter (1) using bolts (14) arranged so that its longitudinal direction is perpendicular to the moving direction (12) of the plunger is the solenoid valve. Therefore, the fixing onto the cover (3) of the air filter is easy.
The noisy sound at the operation of the solenoid valve can be reduced.
