Abstract
A multiple electromagnetic valve comprises a yoke and a port structure held by the yoke. The structure has therein a chamber from which two passages extend to the outside. Two electromagnets are mounted on the yoke, and two armatures for use with the electromagnets are pivotally supported by the yoke. The armatures are pivoted in a first direction when the electromagnets are energized. Springs are employed for biasing the armatures to pivot in a second direction which is opposite to the first direction. Two valve bodies are respectively held by the armatures and arranged to close terminal ends of the passages when the armatures are pivoted in the first direction.
