Title: BOILER FOR A MACHINE FOR PREPARING BEVERAGES
Abstract:
The invention relates to a boiler for a machine for preparing beverages, wherein a fluid is brought to a pressure of at least 8 bars, including at least one diffuser (1) having a first wall (2) to be placed in contact with the fluid to be heated, a second wall (3) opposite the first wall (2) and provided with at least one heating element, at least one body (5) defining, together with the first wall (2) of the diffuser (1), at least one heating chamber, wherein the heating element is a screen-printed or photoengraved resistor. Said boiler has a deformation chamber (7). The chamber is arranged such that, when subjected to the pressure in the heating chamber, the diffuser (1) elastically deforms in the deformation chamber (7) so as at least partially to absorb the pressure force.
