New plunger system for machines designed to obtain the so-called coffee cream, characterized in that on the inner surface of the cylinder traversed by the plunger in its displacements, a hole is opened in communication with the hot water chamber and with the boiler steam through two flat seat valves, the shutter bodies of which are driven by an eccentric cam mounted between them, and are subject to the action of springs, opening on the same surface indicated of the cylinder another hole in communication, through a third valve, with a cold water line, the sealing organ of this latter valve being under the action of an upper peripheral protrusion of the piston, which causes its opening when it is in the top dead center, the piston itself having a groove on its periphery that forms a closed space with the cylinder wall tightly against both the upper chamber and the lower chamber.
