  • Publication number: 20090260708
    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.

  • Patent number: 7481335
    Abstract: A variably proportional mixing device is provided for automatically mixing two fluids stored in separate containers in various ratios without measuring, comprising means for selecting one of a plurality of predetermined mix ratios for the two fluids, and a means for controlling the flow of each fluid from the separate containers so as to achieve a mix ratio that corresponds to the selected ratio. In the preferred embodiment, the means for controlling comprises a trigger operated flow control cylinder which controls the flow of fluid from the first container and the second container, and a ratio cylinder including a channel therethrough having a variable cross-sectional area, the rotation of which using the selecting means varies the flow rate of the fluid from the second container into the flow of fluid from the first container. A static mixer is provided for mixing the two fluids in the spout of the device.
