ABSTRACT:
An improved piston and driver structure includes a synthetic piston body, a bifurcated piston insert and a driver secured within the insert by means of a pin and by means of frictional engagement of the driver by the piston insert when the insert is assembled to the piston body. The piston insert has an enlarged top for dissipating operating pressures over the piston body.
