A microdispensing system is useful for the open-jet dispensing of liquids. A valve having a valve chamber is bounded by an impermeable elastic membrane and is filled with the liquid for dispensing. One or more liquid supply lines lead to the valve chamber. An outlet closed from the exterior by the membrane in the position of rest leads from the chamber to a dispensing nozzle. An actuator chamber is disposed on the other side of the membrane. In the actuator chamber, an electromechanical drive is connected to the membrane for the purpose of briefly lifting the membrane from the outlet. The actuator chamber is closed in such manner that it can be subjected to a pressure differing from atmospheric pressure.
