Abstract
A small low power electromagnetic valve is provided using valving means for providing pneumatic switching. Two orifices connected respectively to the pressure and to the discharge side are alternately closed by a first valving means carried by the plunger core of an electromagnet and respectively by a second valving means associated with a weak spring; a lever receives one end of the plunger core and the active face of said second valving means at pivoting distances, 1 and L, such that ##EQU1## where .phi..sub.1 and .phi..sub.2 are diameters of the orifices.
