Plate (32) is mobile, so that piston ring (1) is opened, until when the internal diameter that piston ring (1) opens is greater than the outer diameter of piston crown, note
Under slide plate (32) and fixed plate (31) at this time relative position scale, piston ring (1) is then removed into piston, to make piston ring
(1) it disassembles, finally, opening according to the scale write down by remaining piston ring (1) and removing piston, realizes rapid batch
Removing of piston ring (1).
