Pneumatic fastener driver

A fastener driver comprising:

• a housing including a handle portion;
• a motor positioned within the housing;
• an air compressor including a compressor cylinder and a compressor piston movable within the compressor cylinder in a reciprocating manner to compress air within the compressor cylinder;
• and
• a drive train converting torque from the motor to a linear force applied to the compressor piston, causing the compressor piston to move in the reciprocating manner,
• wherein at least a portion of the drive train extends through the handle portion of the housing,
• wherein the drive train includes a drive shaft that extends at least partially through the handle portion, and
• wherein the drive train includes a speed reduction mechanism downstream of the drive shaft.

A fastener driver comprising:

• a housing including a handle portion;
• a motor positioned within the housing;
• an air compressor including a compressor cylinder and a compressor piston movable within the compressor cylinder in a reciprocating manner to compress air within the compressor cylinder;
• and
• a drive train converting torque from the motor to a linear force applied to the compressor piston, causing the compressor piston to move in the reciprocating manner,
• wherein at least a portion of the drive train extends through the handle portion of the housing,
• wherein the handle portion includes a first end and a second end, and wherein the drive train includes a first speed reduction mechanism positioned proximate the first end, and
• wherein the drive train includes a second speed reduction mechanism positioned proximate the second end.

A fastener driver comprising:

• a housing including a head portion, a battery attachment portion, and a handle portion extending therebetween;
• a motor positioned within the battery attachment portion;
• a battery pack coupled to the battery attachment portion for providing power to the motor;
• an air compressor including a compressor cylinder and a compressor piston movable within the compressor cylinder in a reciprocating manner to compress air within the compressor cylinder;
• and
• a drive train converting torque from the motor to a linear force applied to the compressor piston, causing the compressor piston to move in the reciprocating manner,
• wherein the drive train includes a drive shaft extending through the handle portion, and
• wherein the drive train includes a speed reduction mechanism downstream of the drive shaft.
