Use compressed air to promote the implementation of the various groups of the combination of cylinder piston, the power of the beam and the identity of the Curves within the orbit of the empty core spindle make rotating movements with the compressed air is discharged through air disk to the cylinder

The multi-groups combine the air cylinder piston motion using the compressed air impetus actuator in, the power transmission for the crossbeam and the inside curve track characteristic, drives the spatial core main axle to make the rotary motion, the compressed air through matches was mad the plate

Using compression air promoted implementation device within more group combination cylinder piston movement, biography force to beam and within curve track of characteristics, led empty core spindle for rotating movement, compression air through distribution gas disc lost to the cylinder, change acc
