摘要

A valve (100) for dispensing a fluid comprising a dry portion (116) and a wet portion (110), only the wet portion (110) being arranged to be contacted by the fluid, the wet portion (110) comprising
- a fluid dispenser unit having a fluid inlet opening, a capillary nozzle (108) providing a fluid outlet, a cavity (202, 206), the capillary nozzle (108) having an end within the cavity (206), and a plunger (106), the plunger (106) being movable within the cavity (206) into an opening position allowing an inflow of the fluid through the fluid inlet opening through the cavity (206) and an outflow of the fluid through the capillary nozzle (108), the plunger (106) further having a sealing surface (212) at its side directed towards the end of the capillary nozzle(108), the plunger (106) being movable into a closing position for sealing the end of the capillary nozzle (108) with the sealing surface (212),
the dry portion comprising
- a closing component (112) for exercising a magnetic closing force onto the plunger (106) for attracting the plunger (106) into the closing position.
