Solenoid air valve

A solenoid air valve comprising:

• a fixed core fixed and adhered to inside of a frame made of a magnetic material;
• in said frame,
• a moving core accommodated in a bobbin made of a non-magnetic material in a manner movable in an axial direction;
• a gas outlet provided in a surface of said fixed core opposed to said moving core;
• a packing provided in a surface of said moving core opposed to said gas outlet;
• force-applying means for applying force to said moving core in a direction away from said fixed core;
• and
• a coil body for generating magnetic flux in order to form a magnetic circuit for generating force attracting said moving core toward said fixed core and bringing the same in contact;
• wherein
• a stop area defining a distance of travel of said moving core in the direction away from said fixed core is provided between a side surface of said moving core and said bobbin,
• said frame has a frame main body and a frame cover covering an end surface opposite to a side where said moving core is accommodated, and
• said frame cover has an opening through which said moving core projects outward.
