Abstract
In a coffee-making machine in which, on raising plunger 10, hot water flows from boiler 13 to cylinder 2 simultaneously along two paths in which heat is dissipated unequally, one path 8, 7, 6 extends through part of the cylinder casing to port 5 and the other through duct 1 and port 3. The change in viscosity which occurs when the water in path 8, 7, 6 cools diminishes the amount delivered through port 5 at each stroke of the plunger and so maintains the mixing temperature in cylinder 2 constant, however much time elapses between successive operations of the machine. When the machine is operated several times in rapid succession, the excess temperature of flow path 8, 7, 6 and the flow rate through it are raised, thus maintaining the same contribution to the heat loss as before and preventing any change in the mixing temperature. The port 3 is advantageously smaller than the port 5. A non-return valve 17 is provided.
