ABSTRACT:
An espresso machine wherein a steam supplying first conduit is separably coupled to a second conduit having an air admitting inlet and an air discharging outlet. When the first conduit admits steam into the second conduit between the inlet and the outlet, such steam draws atmospheric air by way of the inlet and the resulting steam-air mixture is discharged by way of the outlet to frothe milk in a vessel into which the outlet of the second conduit extends. The rate of admission of air into the inlet of the second conduit is regulated by a valving element which is mounted on the second conduit and can be rotated by a handle so as to move a hole of the valving element relative to the inlet and to thus alter the cross-sectional area of the path for the flow of air into the second conduit. If the inlet of the second conduit is completely sealed from the atmosphere, the outlet discharges only steam which can be used to heat cups prior to pouring of espresso coffee.
