Abstract

The machine has a dosing piston in a cylinder for pressing a dosed water quantity in the cylinder through a filter carrier filled with coffee powder and driven by a hydraulically driven working piston connected to it by a piston rod. A sensor device for detecting the piston rod position is provided for dosing the water. The sensor device has a contactless sensor(s) with sensing direction essentially perpendicular to the piston rod axis. The machine has a dosing piston (3) in a dosing piston cylinder (5) for pressing a dosed quantity of water in the cylinder through a filter carrier (7) filled with coffee powder. The dosing piston is driven by a hydraulically driven working piston (2) permanently connected to the dosing piston by a piston rod (6). A sensor device (8) for detecting the position of the piston rod is provided for dosing the quantity of water. The sensor device has at least one contactless sensor whose sensing direction is essentially perpendicular to the piston rod axis.
