ABSTRACT:
A power tool in the form of a fluid pressure cylinder utilizing multiple movable pistons coupled for contemporaneous pressure-responsive working movement, as well as for return to no-load position. Individual pressure buildup on each pressure chamber is controlled by pre-selected imput and exhaust orifice sizes for each chamber, which also permit better control of lubricant dispersal to the successively more remote chambers.
