Abstract

Inventia se refera la un electroventil destinat echiparii aparatelor de ventilatie artificiala a plamînilor atat cu înalta cît si cu joasa frecventa. în scopul obtinerii unei fiabilitati ridicate se compune dintr-un corp realizat din material paramagnetic în care este amplasata o armatura mibila din material feromagnetic, articulata la partea opusa a unui ventil pe niste lagare ceramice producînd bascularea ventilului asezat pe un scaun asigurat de un resort, al carui efeort este reglat de o piulita, armatura care deplaseaza sub actiunea fortelor electromagnetice apprute datorita punerii sub tensiune a unei bobine, fluxul electomagnetic format din armaturile fixa si mobila, întrefierul principal fiind deplasat între armatura mobila si armatura fixa, iar întrefirul secundar la partile laterale ale armaturii mobile rîmanând constant la deplasarea acesteia în timpul functionarii.The invention relates to an electroventile intended for equipping both high and low frequency artificial air ventilation apparatuses. In order to obtain a high reliability it consists of a body made of paramagnetic material in which is placed a malleable armature made of ferromagnetic material, articulated at the opposite side of a valve on some ceramic bearings producing the valve tipping on a seat provided by a spring, whose effect is regulated by a nut, the armature which moves under the action of the electromagnetic forces, due to the tensioning of a coil, the electromagnetic flux formed by the fixed and movable armatures, the main air gap being moved between the movable armature and the fixed armature, and the secondary interference at the parts lateral sides of the mobile armature remain constantly moving it during operation.
