Treatment apparatus with a list of pressure waves moving

摘要

The present invention relates to an apparatus for processing by pressure waves, comprising a chassis (2) carrying an arm (7) is equipped at its end, a pressure wave generator (3), the arm (7) being mounted on the chassis by means of a guide structure (8) enabling the displacement of the generator with respect to the chassis, between at least one position and a retracted position. According to the invention, the guide structure (8) is mounted on the chassis to be inscribed in a housing formed inside the frame and opening out to the outside of the chassis by an opening, the housing being provided for in the retracted position, contain completely the arm (7) and the generator (3) and to allow, by its opening, the output of the arm (7) and of the generator (3) to reach the position of treatment.
