Abstract: 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.

Abstract: A valve for dispensing a fluid comprising a dry portion and a wet portion is presented. Only the wet portion is contacted by the fluid. The wet portion comprises a fluid dispenser unit having a inlet opening, a capillary nozzle providing a fluid outlet, a cavity, the capillary nozzle having an end within the cavity, and a plunger. The plunger moves within the cavity into an opening position allowing an inflow of the fluid through the inlet opening through the cavity and an outflow of the fluid through the capillary nozzle. The plunger has a sealing surface directed towards the end of the capillary nozzle. The plunger moves into a closing position for sealing the end of the capillary nozzle with the sealing surface. The dry portion comprises a closing component for exercising a magnetic closing force onto the plunger for attracting the plunger into the closing position.
