Abstract (en)
[origin: US4694976A] The discharge pump of a discharge apparatus for flowable media is provided with a ventilating channel for the ventilation of the active substance dispenser and the resulting ventilation connection along the channel passes through a bacteria filter. The filter is arranged on a casing of the pump disposed within the reservoir, the filter facing an opening on the casing for the ventilating passage, at a slight spacing from the pump casing. Thus, bacteria which otherwise could penetrate with the ventilating air passing along the ventilating channel from the discharge pump into the reservoir, is held back within the discharge pump.
