<p>A driving mechanism turns a collector shaft (12) having a drive cylinder (DC) (30) with its piston rod linked to a swiveling lever cooperating with a free-wheel (FW) to transfer torque during a piston's advance and to decouple during the piston's return traverse. The FW links to a driving wheel (40) attached with the DC on a mounting (22) to swivel on bearings in a cleaning device's casing.</p> |
