A fluid powered percussion toolhas a housingwith a supply channel for pressurized fluid, a percussion mechanism, a swing jointarranged to carry the percussion mechanismrelative to the housingat a point situated between the forward end A and the rear end B of the percussion mechanism, at least one elastically resilient elementarranged between the housingand the percussion mechanismat a distance from the swinging jointand arranged to load the percussion mechanismagainst a neutral position in the housingand to absorb the vibrational movements of the percussion mechanism, and a flexible connection for pressurized fluidfor distribution of pressurized fluid from the supply channel for pressurized fluidto the percussion mechanism. The elastically resilient elementincludes a conical spring. The flexible connection for pressurized fluidincludes a hose

Fluid powered percussion tool

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.
