ABSTRACT:
A method for assembling a piston on a rod, and resultant piston and rod assembly, uses one or more lock rings that are mechanically deformed radially inwardly into respective locking grooves in the rod, thereby axially locking the lock ring to the rod. The lock ring can function as an axial stop for the piston or can be formed integrally with the piston. The method of assembly minimize unwanted strains and stresses in the piston and rod, while providing a secure and durable joint between the piston and rod.
