PURPOSE:To convert almost all of composite pressure acting on the piston face into the rotation force of a crank by combining a differential gear device as a device to change the force of the circumferential direction of a crank arm with the crank mechanism. CONSTITUTION:When a drive vehicle A turns around a sun gear D fixed by a connecting bar l, the tangential force component of an arm r becomes a gear facial pressure to the sun gear D to turn the sun gear D in the same direction as the arm r. Then, the radial force component of the arm r by connecting bar l becomes a gear facial pressure to another sun gear B. By this, both the sun gears B and D turn in the same direction. If the number of teeth of the sun gear B is equalized with that of the gear D, the angular velocities of both the gears B and D are equalized. Thus, when these are connected by a link F, even the radial force component of the arm r can be returned to an output shaft O3, and therefore, all the pressure acting on the piston P can be taken out of the shaft O3. |
