<p>To provide a solenoid valve allowing to feed different evaporators either individually or simultaneously there is proposed a multi-state solenoid valve using a core element (10) having a coil (12) for magnetisation of the core element. Further, a member (14) with at least one permanent magnet (16) is arranged with respect to the core element (10) such that a relative movement between a member (14) with the permanent magnet (16) and the core element (10) is possible. In addition, the solenoid valve comprises stopper means (18, 20) for limiting the relative movement of the core element (10) and the member (14) between a first and a second limit stop position. According to the present invention the core element (10) only can be energized to move the element (14) with the at least one permanent magnet (16).</p> |
