A powered fastener driver comprising:
- a cylinder;
- and
- a piston positioned within the cylinder, the piston being moveable between a top-dead-center position and a bottom-dead-center position, the piston having a non-circular shape.
A powered fastener driver comprising:
- a first cylinder;
- a first piston positioned within the first cylinder, the first piston being moveable between a top-dead-center position and a bottom-dead-center position;
- a pressure storage chamber in fluid communication with the first cylinder;
- a second cylinder in selective fluid communication with the pressure storage chamber;
- a second piston positioned within the second cylinder, the second piston being moveable between a top-dead-center position and a bottom-dead-center position to initiate a fastener driving operation;
- a drive blade coupled to the second piston for movement therewith;
- and
- a pressure valve positioned between the pressure storage chamber and the second cylinder, wherein the pressure valve is configured to move from a closed position to an open position in response to the pressure within the pressure storage chamber reaching a threshold pressure.
