A dispensing assembly comprising a cartridge holder is presented. The cartridge holder can receive a cartridge for dispensing a fluid. The cartridge can comprise a reservoir for receiving the fluid. The reservoir can comprise an outlet. The reservoir can have an adjustable volume for forcing the fluid through the outlet. The cartridge can further comprise a nozzle for dispensing the fluid. The nozzle can be connected to the outlet. The dispensing assembly can further comprise an actuator for actuating the adjustable volume. The dispensing assembly can further comprise an impulse generator for imparting an impulse to the nozzle. The impulse generator can comprise an actor for contacting the nozzle. The dispenser assembly can further comprise a controller for controlling the actor and the impulse generator.

Dispensing assembly

A device for dispensing or receiving a liquid volume includes a liquid reservoir having an outlet, a pressure generator which provides a compressible enclosed gas volume of a constant amount of substance with a pressure, wherein the gas volume is in direct or indirect fluidic contact with the liquid in the liquid reservoir, a dosing device coupled to the outlet of the liquid reservoir and operable in order to enable the liquid to pass the outlet, a pressure sensor arranged to measure a current pressure in the gas volume and to output an output signal indicating the current pressure in the gas volume and a controller coupled to the pressure generator, the dosing device and the pressure sensor.
