<p>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 position of the rams is determined by the rotational position of the plate cam provided with a guide crank for the rams. …<IMAGE>… </p> |
