Abstract: 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.

Abstract translation: 动力的紧固件驱动器包括气缸和气缸内的驱动活塞，其由压力差产生的驱动力作用。 动力紧固件还包括联接到驱动活塞并可操作以驱动紧固件的驱动叶片，以及用于选择性地将空气从环境大气引入气缸中的可调节阀，从而改变作用在驱动活塞上的压力差。 通过采用如上所述的独立的真空发生装置，本发明不依赖于任何外部真空源，并且方便地使用和携带动力的紧固件驱动器。
