Abstract
A metering apparatus for media includes an applicator with a metering opening, having a pump device having pump parts which can move in the axial direction relative to one another in order to deliver medium out of a medium reservoir to the metering opening, metering chamber with an outlet valve, having a manually operable actuating device, which is operatively connected to the pump device in order to achieve a pump stroke, and spring accumulator, which can be pre-stressed by movement of the actuating device and can be released by a triggering unit as a function of an actuating stroke of the actuating device in order to enable a metering stroke of the pump device to be carried out. The pump device comprises a buffer chamber which, in the event of an actuating stroke, receives a metered volume from the metering chamber and out of which the metered volume is discharged to the metering opening during a metering stroke.
