Chamber dosing valve for the metered dispensing of a viscous medium, comprising a metering unit and a drive unit which are connected to each other, wherein the metering unit comprises at least one media inlet, at which the medium is supplied under pressure to the metering unit, and a media outlet, via which the medium is dispensed from the chamber dosing valve, wherein the metering unit comprises a media chamber having a media entrance and a media exit, wherein the media chamber comprises a metering needle which is movable in an oscillating manner between a forward movement as a metering position and a backward movement as a charging position, wherein, during the backward movement of the metering needle, the medium is pressed into the media chamber as a result of the applied pressure at the media inlet, wherein the metering unit comprises at least two media chambers (5, 6) having a media entrance (7, 7') and a media exit (8, 8'), wherein the media exits (8, 8') of the at least two media chambers (5, 6) open into the media outlet of the metering unit, characterized in that each media chamber (5, 6) comprises a metering needle (9, 10) which in each case is coupled to a cam disk (22, 23), and the cam disks (22, 23) are arranged on a common rotating axle which is coupled to the drive unit such that, as the rotating axle rotates, the metering needles (9, 10) are in each case movable in an oscillating manner between the forward movement as the metering position and the backward movement as the charging position, wherein the at least two cam disks (22, 23) are shaped and arranged offset from each other on the rotating axle in such a way that substantially a forward movement of a first metering needle takes place during a backward movement of a second metering needle, so that the medium is continuously dispensed from the chamber dosing valve. wherein the metering unit comprises a media chamber having a media entrance and a media exit, wherein the media chamber comprises a metering needle which is movable in an oscillating manner between a forward movement as a metering position and a backward movement as a charging position, wherein, during the backward movement of the metering needle, the medium is pressed into the media chamber as a result of the applied pressure at the media inlet, wherein the metering unit comprises at least two media chambers (5, 6) having a media entrance (7, 7') and a media exit (8, 8'), wherein the media exits (8, 8') of the at least two media chambers (5, 6) open into the media outlet of the metering unit, characterized in that each media chamber (5, 6) comprises a metering needle (9, 10) which in each case is coupled to a cam disk (22, 23), and the cam disks (22, 23) are arranged on a common rotating axle which is coupled to the drive unit such that, as the rotating axle rotates, the metering needles (9, 10) are in each case movable in an oscillating manner between the forward movement as the metering position and the backward movement as the charging position, wherein the at least two cam disks (22, 23) are shaped and arranged offset from each other on the rotating axle in such a way that substantially a forward movement of a first metering needle takes place during a backward movement of a second metering needle, so that the medium is continuously dispensed from the chamber dosing valve.
