Patent ID: 7614614

Claim:
An improved venturi apparatus for facilitating the mixture of a liquid and a gas, the apparatus comprising: a. a first funnel section configured to be open to and in fluid communication with the atmosphere, and vertically aligned to receive the liquid due to the liquid being poured and subject to gravity and atmospheric pressure; b. a first cylindrical section fluidly coupled to said first funnel section; c. an intermediate passageway defining a compartment having a ceiling, floor and midsection, said intermediate, passageway having a ceiling diameter greater than a first cylinder diameter of said first cylindrical section, said, first cylindrical section ending at said ceiling; d. at least one sidearm passageway fluidly connected to said intermediate passageway; e. a second cylindrical section fluidly coupled with and extending from said floor of said intermediate passageway; f. a second funnel section fluidly coupled to said second cylindrical section and vertically oriented with the first funnel section, the first and second cylindrical sections, and the intermediate passageway; g. wherein said first funnel section, first cylindrical section, said intermediate passageway, said second cylindrical section and said second funnel section are operative to sequentially receive and define a fluid flow path for the liquid; and h. wherein said fluid flow path extending from said first cylindrical section to said ceiling of said intermediate passageway operatively introduces a decrease in pressure to the liquid passing therethrough and said at least one sidearm passageway is operative to introduce the gas into said intermediate passageway when said liquid passes therethrough at said decreased pressure.
