Abstract
A device for the pneumatic operation of a tool includes a generally closed pressure fluid circuit (), at least one compressor (), for increasing the pressure of the pressure fluid in the circuit, the compressor () having an inlet and an outlet, and a tool driven by the pressure fluid in the circuit, and through which the pressure fluid is transported in the circuit from the outlet to the inlet of the compressor (). The pressure that is generated by the compressor and the load adopted by the tool () are adapted such that the pressure of the returning pressure fluid downstream the tool () is higher than the pressure of the surrounding atmosphere.
