ABSTRACT:
When an armature is displaced by application of a voltage to an electromagnetic coil, a second elastic member contracts in opposition to the restorative force of the second elastic member, wherein a washer, the second elastic member, and the armature are displaced integrally. The armature abuts against the washer, and thereafter a first elastic member is compressed in a direction to close the valve, the first elastic member being compressed in opposition to its restorative force, whereby a main valve body is separated from a valve seat. As a result, exhaust gas is introduced through an inlet port and communicates with an outlet port.
