1. CASE 2286 "GAS REGULATOR-MODULATOR FOR WALL B~ILERS"
The present invention relates to an electromagnetic device of a high s~ructural simpleness and hence very cheap and very easy to be serviced, which allows both the regulation and the modulation to be carried out, by means of the same members, with a high linearity, and hence reliability, as well as rapidity of response to the commands of control of the flow rate of such combustible gases as methane or the like, in such small and medium thermal capacity equipment such as wall boilers, heat generators, and so forth.
From the prior art several types of such dev;ces are already known, but all of the known devices presently ava;lable from the market resuLt complex, bulky and expensive, constituted by many components to be assembLed, which therefore render complex their maintenance; furthermore, the gas pressure regulation is obtaîned by means different from those used for the modulation of the same gas pressure, with consequent further complications.
Furthermore, the adoption in them of calibrated bores and low-diameter passages easily subject to get fouled, renders them not much reliable and furthermore they show high friction and hysteresis values, which do not allow a high linearity~ or a rapid response.
The purpose of the present invention i5 prec;sely that of obviating the above-said drawbacks, and of supplying hence a gas regulator-modulator device wh;ch ;s extremely reliable, simple and not bulky~ and, cor~sequently, cheap, and ~h;ch allows extremely precise 3û results to be obtain~d without accurate machining `` ~3 1~
processes, so that it can be made from cast aluminum.
The said result is substantially achieved by taking advantage of a principle never used in this field, viz., the setting of the outlet gas pressure (the set point) by means of a mobile coil and a stationary magnet, what enabled the present Applicant to combine the functions of pressure regulator and of modulation valve. In other words, the outlet gas pressure is regulated and modulated as a function of the electrical current circulating through the mobile coil.
According to the present invention, there is provided an electroma~netic device for régulation and modulation of a gas in wall boilers, comprising:
- a shutter integral with a regulator membrane adap-ted -to shu-t the flow of gas from a first duct to a second duct;
- means for firmly keeping the shutter in position;
- a coil fastened to the membrane;
- a stationary magnet integral with a guide cylinder facing the coil, the latter being adapted to slide i~ perpendicularly to the membrane inside the stationary magnet guided by the guide cylinder.
The very good characteristics of this electro-magnetic device are in fact obtained by exploiting the repulsion force which is generated between the mobile coil and the magnet, which is directly proportional to the current flowing through the same coil, so that also the force which loads the membrane and, consequently, the shutter, and which determines the value of the outlet gas pressure will be directly proportional to the said current flowing through the coil.
