Abstract

A flow-control valve especially for gasified liquids, for dispensing portions of carbonated water from a storage container for mixing with beverage concentrates in a beverage-vending machine comprises a valve housing, the interior of which broadens from an inlet opening to a chamber in which a membrane with an orifice is arranged orthogonally to the direction of the inflowing water. Water flowing into the chamber passes through the orifice in the membrane and displaces the latter toward a pin which is arranged on the opposite side of the membrane to the inlet opening adjacent to the orifice.
