Abstract
A liquid metering device for a compressed air tool including a sealable liquid tank whose lower part is connected to the compressed air inlet on the tool downstream from a throttle valve, via a through-flow impeding filter element that is in contact with the liquid in the tank. The filter element communicates directly with an upper tank space disposed in the tank above the intended maximum liquid level of the tank.
