Abstract:
1. A fastener driving apparatus for driving a fastener into a substrate, the apparatus comprising: a power source; a control circuit, said control circuit operatively coupled to said power source; a motor, said motor operatively coupled to said power source, said motor responsive to said control circuit; a vacuum piston; a linear motion converter, said linear motion converter operatively coupled to said motor, said linear motion converter operatively coupled to said vacuum piston; a drive piston; an anvil, said anvil operatively coupled to said drive piston; a retention means, said retention means retaining said drive piston in a first position until a sufficient force is applied on the drive piston or until a retention force of said retention means is released; and a cylinder, said vacuum piston capable of reciprocally moving within said cylinder, said drive piston capable of reciprocally moving within said cylinder, wherein during a drive cycle said linear motion converter actuates said vacuum piston such that a vacuum is generated, which vacuum is applied on said drive piston, and when said vacuum reaches a sufficient volume, said retention means releases said drive piston and wherein said drive piston moves from a first position to a second position such that said anvil is capable of driving a fastener into a substrate.
