<p>In a valve of this nature, the armature is held in its momentary switching position by the force of permanent magnets. To change the switching position of the armature, electrical pulses are fed to the electromagnetic system of the valve to cause a variation of the magnetic flux in the area of the yoke and thus a reversal of the position of the armature. The whole magnetic system of the valve is incorporated in one housing. To obtain a magnetic valve for control of fluids which has its structural volume reduced considerably, at least the said housing of the valve is provided with fluid ducting passages, the central space of the magnetic system receiving the pivotably formed armature being divided into two mutually and hermetically separated chambers through which is ducted the fluid which is to be controlled, the two extremities of the armature acting as closing members which close or open corresponding inflow or outflow passages of the said chambers as a function of armature position.</p> |
