Publication number: 20080264662Abstract: A right-handed and reverse air channel button for a pneumatic tool includes a basic body, at least one operating member and two air intake passageways. The basic body is pivotally positioned in a positioning hole of the base of a pneumatic tool, the operating member is secured at one side of the basic body and the air intake passageways are bored in the annular wall of the basic body. When the operating member is turned to actuate the basic body to rotate for a preset angle, the air intake a passageways will respectively correspond to an air intake channel and two guide channels of the base, which communicate with the positioning hole. Thus, air can pass through the basic body and get into the base to drive the pneumatic tool to rotate clockwise or counterclockwise, able to control the air amount, easy in assembly and convenient in operation.Type: ApplicationFiled: April 24, 2007Publication date: October 30, 2008Inventor: Jui-Sheng Chang

Patent number: 7311155Abstract: A pneumatic tool is operable with a single hand. The pneumatic tool includes a shell defining a first chamber and a second chamber. The second chamber includes intake and outlet apertures in communication with the first chamber. A cylinder is in the first chamber. A controller is movable in the second chamber between a first position and a second position. The controller includes a first groove and a second groove. In the first position, the first groove communicates with the intake aperture for directing pressurized air to drive the cylinder in a first direction. In the second position, the second groove communicates with the intake aperture for directing pressurized air to drive the cylinder in a second direction. A cover seals the first chamber and the second chamber. The cover defines an opening through which the controller extends from the second chamber so that the controller can be moved.Type: GrantFiled: December 13, 2005Date of Patent: December 25, 2007Assignee: Mighty Seven International Co., Ltd.Inventor: Jui-Sheng Chang

Publication number: 20070217940Abstract: A pneumatic tool includes a shell, a cylinder positioned in the shell, a rotor eccentrically positioned in the cylinder for rotation and a shaft connected to the rotor and inserted from the interior to the exterior of the shell. The cylinder defines a space for receiving the rotor, a first intake related to a tightening mode, a first channel for communicating the first intake with the space, a second intake related to a slackening mode, a second channel for communicating the second intake with the space, at least one outlet in communication with the space and at least one pressure-releasing vent in communication with the space between the outlet and the first intake so that air vents from the pressure-releasing vent before venting from the outlet in the tightening mode. Blades are connected to the rotor includes so that air can push the blades so as to rotate the rotor.Type: ApplicationFiled: February 15, 2006Publication date: September 20, 2007Applicant: PNEUTECH MANUFACTUER CO., LTD.Inventor: Jui-Sheng Chang

Publication number: 20070166182Abstract: A pneumatic tool is provided with a cylinder assembly. The cylinder assembly includes a cylinder, two steel plates and two covers. The cylinder defines an axial bore, two grooves on an external side and two groups of intakes in communication with the axial bore. Each of the steel plates defines an eccentric opening, two slots and two cutouts in an external edge. The steel plates are located against the cylinder so that the cutouts are in communication with the grooves. Each of the covers defines an eccentric opening and two grooves extending on a side to an external edge. The covers are attached to the cylinder so that the grooves of the cylinder are in communication with the slots through the cutouts and the grooves of the covers.Type: ApplicationFiled: January 19, 2006Publication date: July 19, 2007Applicant: MIGHTY SEVEN INTERNATIONAL CO., LTD.Inventor: Jui-Sheng Chang

Patent number: 7213500Abstract: A pneumatic tool includes a shell defining first, second, third and fourth communicating spaces, a channel communicated with the second space, an inlet communicated with the channel, and an outlet communicated with the second space. A cylinder in the first space defines first, second and third ports. Pressurized air drives a rotor in the cylinder in a direction while entering the cylinder through the first port and leaving the cylinder through the third port and in an opposite direction while entering the cylinder through the second port and leaving the cylinder through the third port. A cover connected to the shell defines an aperture communicated with the second space, a first channel communicated with the third space on one hand and the first port on the other hand, a second channel communicated with the fourth space on one hand and the second port on the other hand. A rotational switch extends into the second space through the aperture and defines two cutouts.Type: GrantFiled: June 28, 2005Date of Patent: May 8, 2007Assignee: Mighty Seven International Co., LtdInventor: Jui-Sheng Chang
