The main valve allows a communication between the cylinder and the first air chamber in conjunction with an operation of the trigger. The housing is formed with a first air chamber, a second air chamber, and a third air chamber. The second air chamber is communicated with the cylinder in conjunction with a movement of the piston. The third air chamber accumulates or discharges the compressed air in the first air chamber in conjunction with the operation of the trigger. The cylinder is movable between a first position where the cylinder upper chamber being in communication with the first air chamber, and a second position where the cylinder upper chamber being blocked from the first air chamber based on a differential pressure between the second air chamber and the third air chamber. | 06-12-2014 |
20150122868 | DRIVING TOOL WITH INTERNAL AIR COMPRESSOR - A driving tool having first and second linear motors, a head assembly, a nosepiece and a driver. The first linear motor forms an air compressor and includes a scotch yoke mechanism for translating a first piston in a first cylinder. The scotch yoke mechanism includes a crank arm, a crank arm roller, which is coupled to the crank arm, and a connecting rod having a roller slot into which the crank arm roller is received. At least a portion of the roller slot is configured to vary an output rate at which the connecting rod translates along a translation axis relative to an input rate at which the crank arm roller moves in a direction that is parallel to the translation axis. | 05-07-2015 |
20150129630 | Driver Tool - A driving tool includes a first piston slidably disposed within a cylinder chamber and having an elongated driving part configured to drive a struck material. A second piston is configured to generate compressed air within the combustion chamber. A compressed air supply passage enables communication between the compression chamber and the cylinder chamber. A valve member opens and closes the compressed air supply passage. A relay member mechanically connects an electric motor with the valve member. The valve member opens and closes the compressed air supply passage via the relay member. | 05-14-2015 |
20150136828 | QUICK-RELEASE TYPE THREE-IN-ONE PNEUMATIC NAILER - The utility invention discloses a quick-release type three-in-one pneumatic nailer, comprising a body, a handle, a magazine, a loading nails hole arranged on the right side of the magazine and a nailer head in front of the body, is characterized in that: a magazine guide bar fixing in the rear of the magazine, a magazine fixing plate is arranged in the higher part of the front side of the magazine; a snap pin is arranged in the nailer head matched with the magazine fixing plate; an angle adjusting block is fixed in the lower part of the handle; the angle adjusting block in provided with a plurality of slots matched with the magazine guide bar.
