摘要

The automatic closure piece for flexible suction lines blocks the current of suction air as soon as operating is finished, and is easily released by hand. The end of the suction hose (14) has a handle (1) with a tubular bend (2) and a guide pipe (3) passes through the bend (2) so that the end of the pipe (3) is the centre of the bottom cross-section of the bend (2). A plunger (4) with a return spring (5) and thumb push-button (6) goes through the guide pipe (3). The suction nozzle has a screen (13) for filtering particles and the lower end of the bend (2) has a locking mechanism (11) for securing the suction nozzle, in the form of a thread, pin, cone or bayonet.
