The pump element is actuatable from the exterior of the reservoir. The delivery side of the pumping element is connected to an infusion chamber assembly which accommodates the coffee powder and is in communication with a dispensing tap opening to the exterior of the reservoir. An hydraulic accummulator is also provided. This hydraulic accummulator branches off a conduit connecting the delivery side of the pumping element to the infusion chamber assembly.
