<p>An apparatus (1) for preparing a beverage suitable for consumption such as coffee on the basis of a hot liquid such as water provided with a storage tank (2), a heater (4) and a three-way valve (7). The three-way valve (7) is provided with an inlet (8), a first outlet (10) and a second outlet (12). The pump (6) is in fluid communication with the storage tank (2) and an inlet (5) of the heater (4). There is a fluid communication between the outlet (14) of the heater (4) and the inlet (8) of the three-way valve (7), between the first outlet (10) and the storage tank (2) and/or an inlet of the pump (6) and between the second outlet (12) and a beverage preparing unit (22) for preparing the beverage suitable for consumption on the basis of the hot liquid. The three-way valve (7) is provided with a first member (26) which is freely movable between a first (26A) and second extreme position (26B) wherein the first member (26) can move under the influence of the liquid flow from the inlet (8) to the first outlet (10) and/or the second outlet (12) from the first extreme position (26A) towards the second extreme position (26B) and in the second extreme position (26B) closes off the first outlet (10) so that the liquid flow then extends from the inlet (8) to the second outlet (12). The three-way valve (7) is further provided with a second member (30) which is freely moveable under the influence of a liquid flow from the inlet (8) to the second outlet (12) between a third (30A) and fourth extreme position (30B) wherein the second member (30), under the influence of the liquid flow from the inlet (8) to the second outlet (12), moves from the third extreme position (30A) to the fourth extreme position (30B) and in the third extreme position (30A) blocks a liquid flow from the second outlet (12) in the direction of the inlet (8).</p> |
