Steam outlet tube assembly for making beverages

摘要

A steam outlet tube assembly (1a) for preparing beverages includes a steam tube (3) having a terminal length portion including an outlet end. The outlet end of a first conduit (10) is located at the terminal length portion of the steam tube (3). There is further provided a second conduit (8) having an outlet end communicating with the steam tube (3) at the terminal length portion thereof; and a mechanism (2) for selectively placing the second conduit (8) into an unblocked position and into a blocked position. In the unblocked position the steam passing through the steam tube (3) draws liquied through the first conduit (10) and draws air through the second conduit (8) to effect a discharge of a steam/liquid/air mixture through the outlet end of the steam tube (3). In the blocked position the steam passing through the steam tube (3) draws liquid through the first conduit (10), to effect a discharge of solely a steam/liquid mixture through the outlet end of the steam tube (3). <IMAGE>
