Problems posed by liquid or gas fuels combustion pollution, requires 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 carburettor as been invented. The mixture valve invented, it is a mixture control valve controlling mixture of a fluid alpha on a second fluid beta , and, it is composed by a set of two calibrated orifices [4] and [5], on a cilindrical tube [2], obturated by the rotative cilindrical pistons [1] and [3]. The fluid alpha flow (liquid ou gas) injected, will be dependent of angular position of the two pistons [1] and [3], and so, it will be a function of two independent control parameters. As an application, it is also, patented, a carburettor for internal combustion engines, using the mixture valve [6] on primary-air flow condut (fluid beta ), controlling the fuel flow (fluid alpha ). Mixture valve it is actuated by two cams [7] and [8], controlled respectively by butterfly valve [11] and by air-flow sensor [7]. <IMAGE> <IMAGE>
