Abstract (en)
[origin: WO2010060448A1] A metering device for the aspiration and dispensing of a metered medium (26) by means of a working substance through a metering opening (22a) into a metering chamber (24), and out of the same, comprises a working chamber (12) filled at least partially with a compressible working substance, a pressure change apparatus (14, 16) which is designed to change the pressure of the working substance in the working chamber, and a metering chamber (24) comprising the metering opening (22a), wherein the working chamber (12) and the metering chamber (24) are connected by a valve (28) which can be switched between a blocking position, in which pressure transmission, in particular a working substance flow, from the working chamber (12) into the metering chamber (24) by way of the valve (28) is prevented, and a passage position, in which pressure transmission from the working chamber (12) into the metering chamber (24) by way of the valve (28) is permitted.
