Abstract:
A dispensing apparatus for fluids from a storage vessel in which a fluid is dispensed through a fluid outlet with the aid of a pump and in which, while the fluid is being dispensed, air flows into the storage vessel through an air inlet which surrounds the pump, and in which a sterile filter is provided for sterilizing, degerminating or reducing germs present in the air to achieve pressure compensation, wherein in a fluid outlet area, surfaces or apparatus which come into contact with the fluid are provided with substances which have an oligodynamic effect or germ-reducing properties for sterilizing, degerminating or reducing the germs in the fluid, the air inlet is formed by a narrow gap between at least one part of the periphery of a piston of the pump and a casing section, and wherein the sterile filter is arranged within the gap between the periphery of the piston and the casing section.
