摘要

The pneumatic cylinder (2) is fitted in a collar (1). Its floor forms a stopper (3) with an inlet channel (4). The pneumatic cylinder (2) is closed by a lid (6), which is fastened to the pneumatic cylinder (2) by a ring (8) to which a microswitch (12) is fixed. In the ring (8) and the lid (6) there is a supply hole (7). In the body of the pneumatic cylinder (2) there is a piston (9) in which there are overpressure channels (9). In the piston (9) there is a piston rod (10) on which there is a plate (13). On the head of the piston rod (10) there is a case (18) with a pin (21) fitted on the bearings (20). On the pin (21) there is a cleaning head (22) in which there are adjustable nozzles (24). In the pin (21) and in the cleaning head (22) there are distribution channels (23) linked to the central channel (101) formed in the piston rod (10).<IMAGE>
