More Information
Summary:A coffee machine comprises a water reservoir, water heater, water pump, coffee vessel for receiving ground coffee and a water delivery system having a water delivery head for delivering heated water to the coffee vessel. A closing and/or tamping system is for compacting ground coffee in the coffee vessel by providing relative movement between the water delivery head and the coffee vessel. The closing and/or tamping system comprises a hydraulic actuator, wherein the water outlet from the water pump is coupled to the hydraulic actuator by a first fluid coupling and the water outlet from the water pump is coupled to the water delivery head by a second fluid coupling which includes a passive in-line valve. The passive in-line valve opens when the pressure reaches a desired pressure.
