ADC AD-410 service manual Tilting Pistons

3.Tilting Pistons

The tilting piston is a double acting cylinder that has a 5-inch bore and an 15-inch stroke. When air is applied to the bottom port of the cylinder, the piston begins to extend and air is exhausted through the top port. Then, if air is applied to the top port, the bottom port will exhaust the air which will cause the piston to retract.
