Devices for preparing a variety of hot drinks, such as, in particular, espresso machines, usually have a multi-path valve (2) which is used for conveying hot water or superheated steam generated in a water heater to different appliances, such as coffee filter, foaming nozzle and/or container. Due to the high temperatures and pressures, the multi-path valve is subject to considerable loads, which known valves cannot withstand or can withstand only if they are of complex construction. In the new device the multi-path valve is provided with a punched plate (8) and a rotatable plate cam (9). Rams (14) for closing distributor channels (5) are passed through the holes of the punched plate. The distributor channels are provided in a distributor block (1) on which the multi-path valve is flange-mounted. The position of the rams is determined by the rotational position of the plate cam provided with a guide crank for the rams. <IMAGE>
