Abstract

There is an air turbine (16) on a tubular shaft (12) sliding axially and carrying a hollow sampling needle (13). Propulsive devices simultaneously rotate the turbine and cause it to slide axially with the shaft. While this is happening, a vacuum is created inside shaft and needle, in order to retain the sample take, when the shaft has slid for a preset distance, release devices shut off the propulsive devices and return rotor and shaft to their starting point. The operator can replace the vauum inside shaft and needle by excess pressure, in order to expel the sample inside. The turbine has a blade-carrying plate acting as a piston to produce the axial movement.
