Abstract
Operating unit for steam discharged from a steam lance in a controlled manner using a manually displaceable operating element. The operating element is displaced in one direction from an engaged starting position, in which there is no steam discharge, into engaged positions for discharge of determined amounts of steam, or displaced in the opposite direction, in which the amount of steam varies with the displacement. The operating element has a fixed casing, an outlet head displaceably mounted on the casing, a steam lance fastened to the head, and a displaceable casing including the operating element. The casing is engaged in the starting position or in the positions or can be displaced in the opposite direction, in which the steam is almost continuously variable. Milk froth is produced optimally according to the desired discharge type, in accordance with the amount of milk located in a cup.
