Abstract
A coffee machine, particularly for espresso coffee, comprising at least one dispensing unit (7) with filter holder (8), a steam generator (1), a heat exchanger (3) in a thermal exchange relationship with said steam generator (1), said heat exchanger (3) being connected, at the inlet, to a source of pressurised cold water via a pipe (21) comprising at least one flow rate calibrating device (22) and, at the outlet, to a first length of pipe (12) directed towards the filter (9) of said dispensing unit (7) via a dispensing valve (10) and a second length (25) of pipe downstream of said valve (10). Said first length of pipe (12) emerging from the heat exchanger (3), upstream of said dispensing valve (10), comprises a connecting channel (13) into which flows a pipe (14), coming from a source (15) of pressurised cold water, including at least one device (17) for controlling the flow rate of the flow of cold water which passes through it.
