Abstract

An electromagnetically driven valve (10) includes a drive valve (14) that has a stem (12); an upper disk (30) and a lower disk (20) each of which has an arm portion (31, 21), and each of which extends from a first end (32, 22) that is movably connected to the stem (12) toward a second end (33, 23) that is movably supported by a disk supporting base (51); and an electromagnet (60). The electromagnet (60) includes a core (61) that is provided so as to face the arm portion (31, 21), and a coil (62) that is wound around the core (61). The electromagnet (60) forms a magnetic circuit (101, 102) that passes through the core (61) and the arm portion (31, 21) when an electric current is applied to the coil (62). The electromagnetically driven valve (10) further includes a permanent magnet (71, 72) which has a magnetic axis along the magnetic circuit (101, 102), and which is provided so as to act on a magnetic flux that flows through the magnetic circuit (101, 102).
