Abstract
A pneumatic motor with dual air intake includes a pneumatic cylinder and a rotor. The pneumatic cylinder includes a cylinder body, and an elliptic-cylinder-shaped accommodating room located in the cylinder body. The cylinder body has two air inletting paths, two air venting paths, two air venting holes and a front axial hole, which communicate with the accommodating room and outside. The rotor includes a rotor body rotatably accommodated in the accommodating room of the pneumatic cylinder, a plurality of grooves parallel provided on the rotor body, a plurality of vanes accommodated in the grooves respectively, and a front axle extended from the rotor body and inserted through the front axial hole. As a result, the pneumatic motor with dual air intake is lowered in friction of the rotor when it rotates, raised in power output, and lowered in vibration when in use.
