More Information
Summary:A coffee machine makes use of a valve arrangement for controlling the coupling of a water heater outlet selectively to one of two or more outlets, such as a steam delivery nozzle and a brew chamber. The valve arrangement comprises an active valve between the inlet channel and a first one of the outlets and a passive valve downstream of the active valve from the water heater outlet, coupled to a second one of the outlets. A cam surface controls the active valve, wherein the angular position of the cam surface controls the coupling of the inlet channel to the first one of the outlets. The rotation may be driven by rotational coupling to a brew chamber motor. This coffee machine design makes use of a single valve arrangement to provide the flow control from the water heater. This provides a compact arrangement with a low component count and simple control mechanism. It also enables all valve mechanisms to be outside the water or steam flow.
