Abstract
A coffee machine for producing and dispensing coffee-based beverages is disclosed comprising a hydraulic pump, at least one dispensing device with a filter unit adapted to contain ground coffee, and a water supply unit. A hydraulic circuit brings the hydraulic pump into fluid communication with the supply unit of the dispensing device to supply hot water under pressure to the supply unit. A system for controlling the dispensing pressure comprises a control unit and a pressure sensor to transmit signals representative of the pressure detected to the control unit to detect the disposing pressure. The hydraulic pump supplies variable quantities of water and may be actuated by an electronic drive controlled electronically by the control unit in order to select the flow of water supplied by the pump. A method for controlling the dispensing pressure in a coffee machine is also disclosed.
