Abstract (en)
An electromagnetically driven valve includes a valve element (14) that has a valve stem (12) and moves in reciprocating motion in a direction in which the valve stem (12) extends; a disc (30) that is interlocked with the valve element (14) at a driving end (32), extending to a pivoting end (33), from which a central axis(35) extends and around which the disc (30) oscillates; a coil (62) that oscillates the disc (30); a power supply (200) that supplies electric current to the coil (62); and an ECU (100) that controls the flow of current from the power supply (200) to the coil (62). During the initial period of operation of the disc, the ECU (100) controls the current so that it is supplied from the power supply (200) to the coil (62) in cycles, and in accordance with the voltage and temperature, controls the number of current cycles, the cycle length, and the value of the current.
