Abstract
A coffee machine of the “espresso” type that includes a water tank, a pump, a heater unit and passages for feeding hot water and steam to a percolation nozzle. The machine includes an integrated steam delivery device having a steam inlet connected to a steam feed passage and a steam outlet. The steam delivery passages include a cylindrical body equipped with an aperture connected to the steam inlet and a cylindrical piece which can move within the body to open or close the steam circuit depending on its position in the body. A control member actuated by a control or trigger finger enables the steam outlet to be brought into contact with the aperture in the closure of a receptacle.
