摘要： An electromagnetically driven valve includes a disc (21) that drives a valve (14), and an electromagnet (51m). The disc (21) includes a first section (26) and a second section (27, 28). The electromagnet (51m) is arranged to face the disc (21), and includes a core portion (52) that attracts the disc (21). The electromagnet (51m) forms a flow of magnetic flux passing through the core portion (52) and the disc (21), thereby exerting an electromagnetic force on the disc (21). A cutting is formed in the disc (21) so that the magnetic path area at the second section (27, 28) is smaller than the magnetic path area at the first section (26). The flow of magnetic flux formed in the disc, before the cutting is formed, has a relatively large magnetic flux density at the first section (26) and a relatively small magnetic flux density at the second section (27, 28).

摘要： An electromagnetically driven valve (10) includes an electromagnet (60) having a coil (62) and generating electromagnetic force, and an upper disc (31) and a lower disc (21) each having a support end (33, 23) and carrying out oscillating movement between a valve-opening position and a valve-closing position around the support end (33, 23). The upper disc (31) and the lower disc (21) are held at a position intermediate between the valve-opening position and the valve-closing position while the electromagnetic force is not applied. As a result of current supply to the coil (62), the electromagnetic force in a direction to move the upper disc (31) and the lower disc (21) to the valve-opening position and the valve-closing position acts on each position (X1, X2) of the upper disc (31) and the lower disc (21). The electromagnet (60) is provided such that a distance L1 between the position (X1) and the support end (33) is different from a distance L2 between the position (X2) and the support end (23). With such a structure, an electromagnetically driven valve of which initial drive is facilitated is provided.
