A multi-path valve arrangement in a beverage making unit by which, optionally, various beverages can be prepared. The multi-path valve arrangement includes a multi-path valve with a housing provided with a cold milk inlet, a cold water inlet, a valve outlet and an air opening. A valve body in the housing is suited to connect the cold milk inlet having an adjustable throttling with the valve outlet. The valve body is set by a step motor which is connected with a programmable control of the valve body position.

1. Multi-path valve arrangement in a beverage making unit, particularly an espresso machine by which optionally various beverages can be prepared and which includes at least one cold milk inlet, a cold water inlet, a valve outlet and at least one valve body via which said cold milk inlet or said cold water inlet may be connected with said valve outlet, wherein said multi-path valve arrangement comprises a multi-path valve having a housing which includes said cold milk inlet, said cold water inlet, said valve outlet and an air opening and in which a valve body is suited to connect said cold milk inlet having an adjustable throttling with said valve outlet,said valve body is adjustable by a step motor,said step motor is provided with a programmable control of the valve body position, anda frothing head is in flow connection with said valve outlet of said multi-path valve and an air solenoid valve,in a first valve body position controlled by said programmable control, said cold milk inlet is connected non-throttled or minimally throttled, respectively, with said valve outlet,in a second valve body position controlled by said programmable control, said cold milk inlet is connected, throttled, with said valve outlet,in a third valve body position controlled by said programmable control, said cold water inlet is connected, non-throttled, with said valve outlet,in a fourth valve body position controlled by said programmable control, said air opening is connected with said valve outlet,said valve body is either shaped as a tap having a plurality of valve paths, in which for milk froth preparation, the tap is rotated by means of the step motor so that a first one of the valve paths is in alignment with the cold milk inlet and a second one of the valve paths following the first valve path is in alignment with the valve outlet, andin order to heat milk, the tap is rotated by means of the step motor so that the first valve path and the second valve path are not completely in alignment with the cold milk inlet and the outlet,or said valve body is shaped as a slider having at least one valve path, in which in order to heat milk, the slider is shifted so that the valve path of the slider is only partially aligned with the inlet and the outlet of the housing. 2. Multi-path valve arrangement according to one of the foregoing claims, wherein said programmable control comprises a selection group and a program storage and control unit. 3. Multi-path valve arrangement according to claim 1, wherein said frothing head is connected, via a milk pipe into which opens an outlet of said air solenoid valve, to said valve outlet of said multi-path valve.
