Abstract
A fastener driving device comprising a pressure chamber, a first piston, a fastener channel and a second piston. The first piston is coupled to the pressure chamber such that pressurized gas in the pressure chamber causes the first piston to slide from a first position to a second position. The fastener channel is configured to receive a fastener, wherein when moving from the first position to the second position the first piston is configured to engage a fastener and drive it from the device. The second piston is slidable within a sleeve and arranged such that when the first piston slides from the first position to the second position the first piston drives the second piston and compresses gas within the sleeve. Compressed gas in the sleeve biases the first piston towards the first position.
