More Information
Summary:The present invention suppresses wear of a rod or a component with which the rod is in contact. An electromagnetic suction valve mechanism (electromagnetic valve mechanism) includes a suction valve (valve body), a rod engaged with the suction valve, and a magnetic attraction force generation unit that generates a magnetic attraction force for moving the rod in an axial direction. The rod is provided with a low friction portion. The low friction portion is set to a friction coefficient such that a frictional force generated between the rod and the rod contact component with which the rod is in contact is smaller than a rotational propulsive force of the rod.
