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: The invention provides, in one aspect, a pneumatic fastener driver including a cylinder and a piston positioned within the cylinder. The piston is moveable between a top-dead-center position and a bottom-dead-center position. The driver also includes a magnetic latch emitting a magnetic field that magnetically attracts the piston and is capable of holding the piston in the top-dead-center position with a magnetic force. The magnetic latch is adjustable to vary the magnetic force acting on the piston for driving fasteners into a workpiece at different depths.

Abstract: A direct current fastening device and related control methods. The fastening device is powered by a direct current power source and includes a variety of safety and control features that allow the fastening device to be safety operated without, for example, a mechanical safety linkage or assembly between a trigger and a fastener firing portion (e.g., a nose switch) that prohibits the operation of the fastening device. Rather, the fastening device described herein employs a controller, a variety of switches, and monitoring techniques to ensure the safe and reliable operation of the fastening device. The configuration of the controller, for example, replaces the mechanical linkages and assemblies between the trigger and the fastener firing portion (e.g., a nose switch) that are ubiquitous safety features for such fastening devices.
Abstract translation: 直流紧固装置及相关控制方法。 紧固装置由直流电源供电，并且包括各种安全和控制特征，其允许紧固装置安全地操作，而不需要例如触发器和紧固件点火部分之间的机械安全联动装置或组件（例如， ，鼻子开关），其禁止紧固装置的操作。 相反，本文所述的紧固装置采用控制器，各种开关和监测技术来确保紧固装置的安全可靠的操作。 例如，控制器的构造代替触发器和用于这种紧固装置的无处不在的安全特征的紧固件点火部分（例如，鼻梁开关）之间的机械连杆和组件。
