ABSTRACT:
A variably proportional mixing device is provided for automatically mixing two fluids stored in separate containers in various ratios without measuring, comprising a self-venting spout that attaches to an existing gas can or other container for storing a fluid having a threaded opening therein. The spout doses gas with oil at the specific ratio required by an engine manufacturer and is easily adjusted to accommodate a plurality of other ratios. To accomplish this, a constant volume of gasoline is dosed with an amount of oil that is adjusted by the user. This adjustment mechanism comprises a wheel valve having various-sized orifices. Twisting the valve using a knob or key then provides the correct volumetric area for the oil to flow through. Markings will be visible on the valve, through a window, that correspond to a plurality of different ratios, typically ranging from 16:1 to 50:1. The dosing valve can also be shut-off completely to allow pure gasoline through the spout, such as for 4 cycle engines. A spring-loaded button or trigger mechanism is incorporated to allow for a positive closure when not in use. Static mixing elements are added at the end of the spout to ensure a thorough mixture of oil and gas.
