Abstract
A pneumatic tool is provided with a cylinder assembly. The cylinder assembly includes a cylinder, two steel plates and two covers. The cylinder defines an axial bore, two grooves on an external side and two groups of intakes in communication with the axial bore. Each of the steel plates defines an eccentric opening, two slots and two cutouts in an external edge. The steel plates are located against the cylinder so that the cutouts are in communication with the grooves. Each of the covers defines an eccentric opening and two grooves extending on a side to an external edge. The covers are attached to the cylinder so that the grooves of the cylinder are in communication with the slots through the cutouts and the grooves of the covers.
