Abstract
Apparatuses for the preparation of different hot drinks, such as in particular espresso machines, conventionally have a multiway valve (2), which is used for supplying hot water or superheated steam produced in a water heater to different means, such as coffee filters, frothing nozzle and/or collecting vessels. As a result of high temperatures and pressures the multiway valve is exposed to considerable stresses, which in the long term cannot be withstood by known valves or only when a complicated and costly construction is adopted. In the novel apparatus the multiway valve is provided with a perforated disk (8) and a rotary control dial (9). Rods (14) for closing the distributing passages (5) are passed through the holes in the perforated disk. The distributing passages are provided in a distributing block (1) to which the multiway valve is flanged. The position of the rods is determined by the rotary position of the control dial provided with a guide link for the rods.
