Abstract:
1. A fastener driving apparatus, comprising: a power source; a motor electrically connected to the power source; a first cylinder comprising a slider crank arrangement driven by the motor, the slider crank arrangement operationally coupled to the first piston and configured to cause the first piston to reciprocally move within the first cylinder; a second cylinder comprising a valve arrangement operationally disposed between the first cylinder and the second cylinder, the valve arrangement defining a gas passageway for communicating the gas from the first cylinder to the second cylinder and the valve arrangement capable of assuming one of an open position and a closed position; wherein the gas received within the gas chamber is compressed by the first piston in a single stroke of the slider crank arrangement in a manner such that the compressed gas is communicated into the second cylinder through the gas passageway of the valve arrangement, causing the compressed gas to expand in the second cylinder thereby causing the second piston to move linearly and enabling the anvil to drive a fastener into a substrate in the driving direction in the single stroke of the slider crank arrangement.
