ABSTRACT:
The invention relates to a piston vibrator comprising a case with at least one cylindrical bore (5), at least one air connection (7) taken laterally to the bore (5), and a piston (2) longitudinally displaceable in the bore (5). As a means of making such a vibrator more efficient with a given outside diameter, or as a means of making it more compact and smaller with the same degree of efficiency, the invention proposes that the cylindrical bore (5) should extend asymmetrically to the external wall area (6) of the case, at least at the axial level of the air connection (7).
