ABSTRACT:
A pressure splitter is made having a series or orifices, at least one of which has its effective size change with changes in temperature. This size change is provided by using materials with different thermal expansion rates, these different rates changing the relative positions of a body and the free end of a temperature responsive member. This same principle can be used in conjunction with a pressure responsive element, such as a sealed bellows, to provide a splitter which has an intermediate pressure which changes in response to both temperature and pressure. A splitter with temperature compensation only can be used to effectively modify carburetor fuel flow providing a more constant fuel/air ratio. A splitter using both temperature and pressure responsive elements can be used to more effectively maintain carburetor fuel/air ratio over a wide range of relative air densities caused by changes in atmospheric temperature and altutude.
