  • Electromagnetic actuator and integrated actuator and fluid flow control valve
    Patent number: 7021603
    Abstract: A magnetic device is formed from a permanent magnet generating magnetic flux, an armature which can occupy two positions between four poles and an electromagnet winding to which current can be supplied to produce a magnetic flux in one direction or the other, the flux from the winding causing the armature to move into one position and continue to remain in that position after the current flow ceases. The device can be incorporated into a fluid valve to act as a drive for opening and closing the valve. It may also serve as the drive for opening and closing electrical contacts. Monostable operation can be achieved by locating a magnetic flux shunt at one end of the armature travel. A holding solenoid may be incorporated. A pivoting armature in a fluid tight chamber comprises a fluid flow controlling device. It can adopt either of two home positions in contact with two magnetic poles and is retained by magnetic flux from a permanent magnet. Fluid can flow into and out of the chamber via a first passage.
