摘要： This invention discloses a magnetically latching solenoid valve and a solenoid thereof. The solenoid includes a coil disposed around a bobbin and divided into two sections by a tap for adjustable pull and release forces to a plunger disposed therein. A first section of the coil, through magnetic induction, pulls the plunger toward a fixed stopper disposed at the lower end of the bobbin and coupled to a cylindrical yoke. A permanent magnet is disposed between the stopper and the yoke. On contact with the stopper, the plunger is held in place by the permanent magnet even after the current flow is removed from the first section of the coil. A second section of the coil, with a differing magnetic induction, returns the plunger. By the operating current at the common tapped junction of the coil, the electromagnetic force generated by the first section will add to the fixed force from the permanent magnet while the electromagnetic force generated by the second section will subtract from the fixed force from the permanent magnet. By using a tapped coil, a simpler and more efficient electronic drive can be used with reduced electrical switching losses.
