    • A pneumatic fastener includes a housing and a handle coupled to the housing. The handle defines an inlet channel for delivering compressed gas to the housing. A trigger valve is in communication with the inlet channel and configured to actuate the pneumatic fastener. A fastener driving assembly is disposed within the housing. The fastener driving assembly includes a cylinder and a piston that reciprocates within the cylinder to drive a fastener. A valve piston is coupled to the fastener driving assembly. Actuation of the valve piston causes compressed air to drive the piston within the cylinder to drive the fastener. An outer cap is coupled to the housing and an inner cap is disposed at least partially within the outer cap. The inner cap includes an opening in communication with the trigger valve for porting the compressed air to a region above the valve piston.
    • 气动紧固件包括壳体和联接到壳体的手柄。 手柄限定了用于将压缩气体输送到壳体的入口通道。 触发阀与入口通道连通并且构造成致动气动紧固件。 紧固件驱动组件设置在壳体内。 紧固件驱动组件包括气缸和在气缸内往复运动以驱动紧固件的活塞。 阀活塞联接到紧固件驱动组件。 阀活塞的致动使压缩空气驱动气缸内的活塞以驱动紧固件。 外盖联接到壳体,并且内盖至少部分地设置在外盖内。 内盖包括与触发阀连通的开口,用于将压缩空气移入阀活塞上方的区域。
