A powered fastener driver includes a cylinder and a drive piston within the cylinder being acted on by a driving force resulting from a pressure differential. The powered fastener further includes a drive blade coupled to the drive piston and operable to drive a fastener, and an adjustable valve for selectively introducing air from ambient atmosphere into the cylinder, thereby changing the pressure differential acting on the drive piston. By adopting a self-contained vacuum generating means as described above, the present invention does not rely on any external vacuum source and powered fastener driver can be used and carried with conveniently.

Powered fastener driver and operating method thereof

A drive blade lubrication assembly for use in a powered fastener driver (). The powered fastener driver () contains a drive blade () which snap-fits with a reciprocating piston () by a blade seal () assembly. The drive blade lubrication assembly contains a lubricant applying member adapted to apply lubricant to a portion of the drive blade (); and a lubricant storing device which is in fluid communication with the lubricant applying member. The lubricating storing device is adapted to replenish the lubricant in the lubricant applying member. A powered fastener driver () containing a drive blade lubrication assembly is also described. The use of the lubricant storing device in the present invention ensures that lubricant is continuously supplied to the drive blade () after long time usage of the powered fastener driver (), so that friction between the drive blade and the blade seal assembly is minimized.
