A faucet for dispensing flat malt beverage and a smooth, creamy and stable foam having a shiftable faucet shaft which in one position dispenses flat beer and in a second position provides an alternate flow path through restricted orifices which increase the velocity of the malt beverage so that it draws air into the faucet housing through orifices therein and incorporates the air into the foam to dispense a stable, creamy foam from the faucet discharge port.

A faucet for dispensing malt beverages comprising a faucet housing having a discharge port, said faucet housing being connectable to a cource of malt beverage, and valve means in the faucet housing shiftable between shut-off, full flow flat beer dispensing and restricted flow foam dispensing positions, said housing including a chamber, a main passage of smaller cross-sectional area than said chamber and connected thereto, an internal shoulder at the connection, and a guide chamber aligned with said main passage and separated from the main chamber by the discharge port, said housing being provided with air inlet means for admitting air into the dishcharge port to vent the housing when the valve means is in the shut-off position and for incorporation into the malt beverage as it is dispensed after it leaves the said chamber and enters the discharge port when the valve means is in the restricted flow foam dispensing position, said valve means including a guide member shiftable in the guide chamber and loosely positioned therein, a reduced shaft connecting the guide member and a valve seat retaining flange, the flange being freely reciprocable with the meain passage between a position generally concentric with respect to the internal shoulder and a position shifted into the main passage to define a cylindrical chamber, a hollow stem terminating at the flange and positioned in the said chamber, and a valve seat movable with and relative to the stem and adapted to engage the internal shoulder when the valve means is in shut-off and foam dispensing positions, the hollow stem being provided with discharge ports adjacent to the flange, the ports being sealed by the valve seat when the valve is in shut-off and flat beverage dispensing positions and being open when the valve is in foam dispensing position to admit malt beverage transversely into the cylindrical chamber adjacent to the flange, the flange being provided with a series of small orifices therethrough at its periphery whereby the malt beverage discharges from the cylindrical chamber into the main passage and has an increased velocity as it enters the main passage longitudinally from the orifices, said velocity being sufficient to draw air through the air inlet means and past the loosely positioned guide member into the housing and incorporate it into the malt beverage to form a thick, creamy, stable foam.
