摘要： Problems posed by liquid or gas fuels combustion pollution, require that at any instant a better primary air-fuel mixture is needed. A non adequated excess-air factor will be the source for an incomplete combustion with formation of pollutants. In order to solve these problems a fluid mixture control valve that can be used as part of a carburator has been invented. The mixture valve of the invention is a mixture control valve controlling mixture of a fluid alpha on a second fluid beta , and consists of a set of two calibrated orifices (4) and (5), on a cylindrical tube (2), obturated by the rotative cylindrical pistons (1) and (3). The fluid alpha flow (liquid or gas) injected will be dependent on angular position of the two pistons (1) and (3), and so will be a function of the two independent control parameters. Also disclosed as an application is a carburator for internal combustion engines, using the mixture valve (6) on primary air flow duct (fluid beta ), controlling the fuel flow (fluid alpha ). The mixture valve is actuated by two cams (7) and (8), controlled respectively by butterfly valve (11) and by air-flow sensor (7).
