A liquid ejection device for a vehicle washing facility comprises a storage volume, a first supply line coupled upstream to the storage volume for supplying a first liquid, a supply unit coupled upstream to the storage volume for supplying a second liquid, and a removal line coupled downstream to the storage volume for discharging the liquid to be ejected, with a shut-off device for shutting off liquid flow through the removal line. The storage volume is sealed so that an increase in an internal gas pressure occurs in the storage volume when liquid is introduced. The device further comprises a detection unit for detecting the supplied volume of the second liquid into the storage volume and the internal gas pressure in the storage volume, and a control unit controls the supply of the second liquid based on the detected supplied volume of the second liquid and the internal gas pressure so that a predetermined mixing ratio of the first and second liquid is achieved in the storage volume.
