Pneumatically operated nailing device in particular to be used on metal, comprising piston serving as valve

摘要

The piston (12) of the pneumatically operated nailing device (2) is moved by the pilot system (34) activated by an electromagnetic valve (36). The pressure duct (26) is opened after a short move of the piston (12) serving as a valve and immediately impinged on by the full pressure. The surface (18) of the piston (12) is of the same dimension as the accelerating tube (6) resulting in an extreme amount of highly compressed air acting within an extremely short period on the piston (12) which is accelerated accordingly.
