linearrotarypiston

For clockwise output, apply pressure to P2, which force the pistons to move together. The volume between the pistons isexhausted atPl. For counterclockwise output, apply pressure to PI, which force the pistons apart. The linear travel of the pistons is converted to a rotation of the drive shaft by the rack to pinion connection. The volume outside each piston is exhausted at P2. NOTE: When required Reverse Rotation the pistons can be inverted in the housing resulting in a clockwise rotation when pressure is applied to PI
