ABSTRACT:
A piston/piston rod assembly. The piston is an annular member which is provided with a longitudinal bore therethrough having internal threads therein. A transverse opening is provided through the piston. The piston rod is provided with a threaded end for threaded engagement with the threaded portion of the piston. A transverse opening is provided through the piston rod. A pin is seated in the transverse openings of the piston and piston rod, responsive to assembly of the piston and piston rod, to retain the piston securely on the piston rod. The transverse openings are disposed to retain the pin therein to prevent movement of the piston on the piston rod, but yet allow a certain amount of adjustment of the piston relative to the piston rod during the assembly thereof.
