<p>A pressure regulating system with amplifier is provided for preparing the mixture of a gas with air for a combustion engine. The pressure regulating system comprises a first (9) and second (14) inlet conduit opening in a first chamber (13) through which gas is supplied under constant pressure. The first inlet conduit (9) is separated from the first chamber by a valve (12) connected to a diaphragm (10). The second inlet conduit (14) comprises an adjustable restriction (15), through which a constant small quantity of gas being delivered to the first chamber (13). The pressure regulating system also comprises an outlet conduit (31) being directly connected to the first chamber (13) and to the inlet of the user and a second chamber (23) being separated from the first chamber by said diaphragm (10). To said second chamber (23) a third inlet conduit (16), provided with an adjustable restriction (19), is connected, through which a constant small quantity of gas is delivered to the second chamber. The second chamber (23) is also connected to the first chamber i.e. outlet conduit, through a variable restriction (18).</p> |
